ncurses: remove builtin Interix support

ncurses: Put back fake ncurses.pc handling.

Fixes build of e.g. editors/mg on macOS using builtin ncurses.

ncurses: Remove faked-up files.

Some of this has already been moved to mk/curses.buildlink3.mk, and the
rest is obsolete now that this file will only be included if we are
specifically using ncurses and not some other implementation pretending
to be ncurses.

ncurses: Remove USE_NCURSES support.

This was superseded by USE_CURSES many years ago.  If this file is being
included then we are already using ncurses.

This only removes support for the variable, removing it from individual
packages will come later.

ncurses: Remove USE_TERMINFO.

This is a long-obsolete variable, support was moved to
mk/terminfo.buildlink3.mk many years ago.

ncurses: Remove INCOMPAT_CURSES.

This was moved to mk/curses.builtin.mk over 10 years ago.

ncurses: Remove NetBSD builtin hack.

If this file is being included, then the package has specifically
requested ncurses.  This code was committed in 2005 and since then the
pkgsrc curses handling has been revamped significantly.

ncurses: Remove pointless comment.

*/builtin.mk: Use ${_CROSS_DESTDIR:U} for build-time file checks.

These are questions about the target system, whose files at
build-time are all relative to ${_CROSS_DESTDIR} if it is defined,
i.e., if USE_CROSS_COMPILE is set to yes.

No change to native builds because ${_CROSS_DESTDIR:U} is empty in
them.  (Possible minor change by adding :Q to ${H_FOO} in command
lines, but if this makes a difference it likely fixes problems.)

ncurses: update to 6.4.

   The   most  important  bug-fixes/improvements  dealt  with  robustness
   issues.  The  release notes also mention some other bug-fixes, but are
   focused  on  new  features and improvements to existing features since
   ncurses 6.3 release.

  Library improvements

    New features

   There are no new features in this release.

    Other improvements

   These are improvements to existing features:
     * modify  delscreen  to  more  effectively delete all windows on the
       given screen.
     * modify  wnoutrefresh  to  call  pnoutrefresh if its parameter is a
       pad,  rather than treating it as an error, and modify new_panel to
       permit its window-parameter to be a pad
     * modify  curses_trace()  to  show  the trace-mask as symbols, e.g.,
       TRACE_ORDINARY, DEBUG_LEVEL(3).
     * improve  checks  for valid mouse events when an intermediate mouse
       state is not part of the mousemask specified by the caller
     * allow extended-color number in opts parameter of wattr_on.
     * improve _tracecchar_t2 formatting of base+combining character.
     * trim  out some unwanted linker options from ncurses*config and .pc
       files seen in Fedora 36+.
     * improve shell-scripts with shellcheck
     * improve use of "trap" in shell scripts, using a script.
     * modify make-tar.sh scripts to make timestamps more predictable.

   These are corrections to existing features:
     * modify  misc/gen-pkgconfig.in  to  allow  for  the  case where the
       library  directory  does  not  yet  exist, since this is processed
       before doing an install
     * set trailing null on string passed from winsnstr to wins_nwstr.
     * modify  waddch_literal  to  allow  for double-width base character
       when merging a combining character

  Program improvements

   Several improvements were made to the utility programs:

   infocmp

          + rewrite  canonical_name  function of infocmp to ensure buffer
            size
          + improve  readability  of  long parameterized expressions with
            the  infocmp  "-f"  option  by  allowing  split before a "%p"
            marker.
          + modify   verbose-option   of  infocmp,  tic,  toe  to  enable
            debug-tracing if that is configured.

   tabs
          limit tab-stop values to max-columns

   tic
          add   consistency   check   in   tic  for  u6/u7/u8/u9  and  NQ
          capabilities.

   tput
          corrected use of original tty-modes in init/reset subcommands

    Examples

   Along  with  the  library and utilities, improvements were made to the
   ncurses-examples.  Most  of  this  activity  aimed  at  improving  the
   test-packages:
     * add  minimal  -h  (usage)  and  -V  (version)  getopt logic to all
       ncurses-examples programs.
     * fix an error in "@" command in test/ncurses.c F-menu
     * add curses_trace to ifdef's for START_TRACE in test/test.priv.h
     * improve pthread-configuration for test/worm.c
     * add setlocale call to several test-programs.
     * workaround  in  test/picsmap.c  for  use of floating point for rgb
       values by ImageMagick 6.9.11, which appears to use the wrong upper
       limit.
     * use  static libraries for AdaCurses test-package for Mageia, since
       no gprbuild package is available.
     * install  Ada95  sample  programs  in  libexecdir, adding a wrapper
       script to invoke those.
     * install  ncurses-examples programs in libexecdir, adding a wrapper
       script to invoke those.

   There are other new demo/test programs and reusable examples:

   test/combine
          demonstrate combining characters

   test/test_delwin
          demonstrate deleting a window

   test/test_mouse
          observe  mouse  events  in  the  raw terminal or parsed ncurses
          modes

   test/test_unget_wch
          demonstrate the unget_wch and unget functions

  Terminal database

   There are several new terminal descriptions:
     * mosh
     * mosh-256color
     * teken-16color
     * teken-sc
     * teken-vt
     * xgterm

   There  are  many  changes to existing terminal descriptions. Some were
   updates to several descriptions:
     * make description-fields distinct
     * fix errata in description fields
     * add/use several building-blocks:
          + aixterm+sl
          + ansi+cpr
          + apollo+vt132
          + decid+cpr
          + ncr260vp+sl
          + wyse+sl
          + x10term+sl
          + xterm+acs
          + xterm+alt47

   while  others  affected specific descriptions. These were retested, to
   take into account changes by their developers:
     * kitty
     * teken

   while  these are specific fixes based on reviewing documentation, user
   reports, or warnings from tic:

   att610+cvis0
          amended note as per documentation for att610, att620, att730

   kon, kon2, jfbterm
          revise to undo "linux2.6" change to smacs/rmacs/enacs

   st-0.6
          add dim, ecma+strikeout

   foot+base
          add xterm+sl-alt

   dec+sl
          correct dsl in dec+sl

   mintty and tmux
          correct setal in mintty/tmux entries, add to vte-2018

   nsterm
          modify nsterm to use xterm+alt1049

   putty
          modify putty to use xterm+alt1049

   vte-2018
          add blink and setal

   A few entries use extensions (user-defined terminal capabilities):
     * use  ansi+enq  and  decid+cpr in cases where the terminal probably
       supported the u6-u9 extension
     * remove u6-u9 from teken-2018
     * use  NQ  to flag entries where the terminal does not support query
       and response
     * add/use bracketed+paste to help identify terminals supporting this
       xterm feature
     * modify  samples  for xterm mouse 1002/1003 modes to use 1006 mode,
       and also provide for focus in/out responses
     * xterm  patch  #371 supports DEC-compatible status-line. add dec+sl
       to  xterm-new, per xterm #371, add xterm-p371, add xterm-p370, for
       use  in  older  terminals, and set "xterm-new" to "xterm-p370" (to
       ease adoption).

  Documentation

   As usual, this release
     * improves documentation by describing new features,
     * attempts  to  improve the description of features which users have
       found confusing
     * fills  in overlooked descriptions of features which were described
       in the NEWS file but treated sketchily in manual pages.

   In  addition  to  providing  background  information  to explain these
   features   and   show   how   they  evolved,  there  are  corrections,
   clarifications, etc.:
     * Corrections:
          + remove a stray '/' from description of %g in terminfo(5).
          + correct/improve  font-formatting in curs_getch.3x, as well as
            other manual pages.
     * New/improved history and portability sections:
          + add portability notes for delscreen and delwin in manual.
          + improve curs_slk.3x discussion of extensions and portability
     * Other improvements:
          + improve  curs_bkgd.3x,  explaining  that  bkgdset  can affect
            results for bkgd
          + add note on portable memory-leak checking in curs_memleaks.3x
          + expanded description in resizeterm.3x
          + add  section  on  releasing  memory  to  curs_termcap.3x  and
            curs_terminfo.3x manpages.
          + add  clarification  of  the  scope  of  dynamic  variables in
            terminfo(5).
          + improve formatting of ncurses-intro.html and hackguide.html
          + improve curs_clear.3x links to other pages
          + update  ncurses-howto,  making documentation fixes along with
            corrections to example programs.
          + use  newer  version  1.36 of gnathtml for generating Ada html
            files.
          + update external links in Ada95.html

   There  are  no new manual pages (all of the manual page updates are to
   existing pages).

  Interesting bug-fixes

   While  there  were  many bugs fixed during development of ncurses 6.4,
   only  a  few  (the  reason  for  this release) were both important and
   interesting. Most of the bug-fixes were for local issues which did not
   affect  compatibility across releases. Since those are detailed in the
   NEWS file no elaboration is needed here.

   The  interesting  bugs were those dealing with memory leaks and buffer
   overflows.  Although  the utilities are designed for text files (which
   they do properly), some choose to test them with non-text files.
     * Text  files  contain  no  embedded  nulls.  Also,  they end with a
       newline.  Feeding tic non-text files exposed a few cases where the
       program  did  not  check  for  those  issues. As a result, further
       processing  of the input found limit-checks whose assumptions were
       invalid.
     * Fixing  the limit-checks (first) found a problem with tic managing
       the  list  of  strings  in  a terminal description. In merging two
       terminal  descriptions  (i.e.,  the  "use="  feature), tic was not
       allocating  a  complete copy. A quick repair for that introduced a
       memory leak.
     * The  checks  for non-text files are improved (i.e., embedded nulls
       in  the  input  file  will  cause  tic  to  reject  it rather than
       attempting to process it).
     * The string allocations in tic are likewise improved.

  Configuration changes

    Major changes

   There  are  no  major  changes.  No  new  options  were added. Several
   improvements were made to configure checks.

    Configuration options

   There are a few new/modified configure options:

   --with-abi-version
          add ABI 7 defaults to configure script.

   --with-caps
          add   warning   in  configure  script  if  file  specified  for
          "--with-caps" does not exist.

   --with-manpage-format
          bzip2 and xz compression are now supported

   --with-xterm-kbs
          add    check/warning    in    configure    script   if   option
          "--with-xterm-kbs" is missing or inconsistent

  Portability

   Many  of  the  portability  changes  are implemented via the configure
   script:
     * amend  configure option's auto-search to account for systems where
       none of the directories known to pkg-config exist
     * corrected regex needed for older pkg-config used in Solaris 10
     * improve  handling of --with-pkg-config-libdir option, allowing for
       the case where either $PKG_CONFIG_LIBDIR or the option value has a
       colon-separated list of directories
     * if   the   --with-pkg-config-libdir   option  is  not  given,  use
       ${libdir}/pkgconfig as a default
     * improve search-path check for pkg-config, e.g., for Debian testing
       which installs pkg-config with architecture-prefixes.
     * build-fix for cross-compiling to MingW, conditionally add -lssp
     * improve configure check for getttynam
     * fixes to build with dietlibc:
          + add configure check for fpathconf
          + add   configure   check   for  math  sine/cosine,  needed  in
            test/tclock, and eliminate pow() from test/hanoi
          + use wcsnlen as an alternative to wmemchr if it is not found
     * modify  configure macro CF_BUILD_CC to check if the build-compiler
       works,  rather  than that it is different from the cross-compiler,
       e.g.,  to  accommodate  a  compiler  which  can be used for either
       purpose with different flags
     * modify  configure/scripts  to work around interference by GNU grep
       3.8

   Here are some of the other portability fixes:
     * change  man_db.renames  to  template,  to  handle  ncurses*-config
       script with the --extra-suffix configure option.
     * update   CF_XOPEN_SOURCE  macro,  adding  variants  "gnueabi"  and
       "gnueabihf" to get _DEFAULT_SOURCE special case, as well as adding
       GNU  libc  suffixes for "abi64", "abin32", "x32" to distinguish it
       from other libc flavors.
     * work  around  musl's  nonstandard  use  of  feature test macros by
       adding  a  definition  for NCURSES_WIDECHAR to the generated ".pc"
       and *-config files.
     * use  "command  -v"  rather than "type" in Ada95/gen/Makefile.in to
       fix a portability issue.

devel/ncurses: Add fake pc file

Add support for creating ncurses.pc in the buildlink dir, either by
linking to the base one, or creating a fake one.  More or less copied
from ../libuuid/builtin.mk.

   Log Message:
   Recognize libgnuform as valid implementation of a form library to match
   devel/ncurses. This is necessary due to cmake's insistance of scanning
   PREFIX/lib directly. Bump revision.

Drop buildlink-ncurses-fake-libs, it didn't get applied due to a typo
and it doesn't help with the directory scanning of cmake anyway, since
that one only looks in the real prefix.

For the sake of cmake and other tools that like to look for physical
files, create dummy libraries for libform and co.

Rename ncurses's libform, libpanel and libmenu to libgnuform,
libgnupanel and libgnumenu as they overlap with system libraries on
NetBSD, resulting in strange breakage like in devel/cmake's ccmake
frontend.

Remove INCOMPAT_CURSES settings for NetBSD 0.x and 1.x.  Tighten up some
globs to ensure NetBSD 10 is not incorrectly matched when it is released.

Use a (shell) "for" loop to deal with creating the symbolic links for both
include filenames instead of duplicating the code.

Also create "ncurses/ncurses.h" if we are using a builtin curses library.

Some packages (e.g. "cmake" version 3.0.1) automatically discover
"${PREFIX}/include/ncurses/ncurses.h" and derive the include filename
from this path.

Use find-headers instead of find-files to detect builtin header files.

backout solaris ncurses builtin support until /usr/gnu/lib dependencies can be sufficiently worked out

update ncurses builtin.mk for solaris(illumos)

Changes 5.8:
Interface changes
* turn on _XOPEN_CURSES definition in curses.h.
* change _nc_has_mouse to has_mouse, reflect its use in C++ and Ada95.
* add is_pad and is_subwin functions for opaque access to the WINDOW structure.
* add tiparm, based on review of X/Open Curses Issue 7.

Library Improvements
* add a terminal driver for Windows console, which supports a MinGW port to
  Windows.
* add extended functions which specify the SCREEN pointer for several curses
  functions which use the global SP.
* improve the NCURSES_NO_UTF8_ACS feature by adding a check for an extended
  terminfo capability U8.
* improve performance of tigetstr, etc., by using hashing code from tic.
* add WACS_xxx definitions to wide-character configuration for thick- and
  double-lines.
* modify init_pair to allow caller to create extra color pairs beyond the
  color_pairs limit, which use default colors.

Improvements to Programs
* add tabs program.
* modify tic's -I/-C dump to reformat acsc strings into canonical form (sorted,
  unique mapping).
* add checks in tic for inconsistent cursor-movement controls, and for
  inconsistent printer-controls.
* add special case to _nc_infotocap (used by tic and infocmp) to recognize the
  setaf/setab strings from xterm+256color and xterm+88color, and provide a
  reduced version which works with termcap.

Tell location of Haiku's ncurses header.

Fix previous; I did test it, but it seems that under some
circumstances make doesn't like the conditional I wrote.

(also, what the previous log message says about a bump is wrong; I bumped
only ncursesw. but there shouldn't be any need to bump ncurses for this.)

The change in -r1.27 of this file failed to restore the old logic
completely; rectify that. Now setting USE_NCURSES=yes won't install
pkgsrc ncurses on e.g. Linux where it's really built in.

Not sure if a version bump is wanted, but since I just did one we'll
ride that.

oops, the simple case USE_NCURSES=yes got lost, add it as separate
clause for readability

add another optional condition for curses suitability: support
of wsyncup

if terminfo is needed and we don't have it, use pkgsrc ncurses

Make USE_NCURSES more specific. Allow selecting chgat as feature, so
that more packages can work without ncurses on NetBSD 5.99.14+.

Actually, BUILTIN_LIBNAME.ncurses can be empty, but fix the case where
we actually have libnurses in the base system.

+ Always ensure that BUILTIN_LIBNAME.ncurses is defined (this should have
  been the case before, but wasn't due to a missing default vaule.

+ Move the BUILDLINK_TRANSFORM remapping of -lncurses into the section
  which only applies if we're using the built-in ncurses, and map it to
  -l${BUILTIN_LIBNAME.ncurses}.

This should fix the issue reported for Mac OS X where "-lncurses" was
being mapped to nothing by the wrapper scripts.

Backout last change, it breaks the build under NetBSD.

Don't setup bogus remapping of the "ncurses" library if we don't need
to change the name. This fixes the build on platforms which provide
"libncurses" (e.g. Mac OS X).

+ Define BUILTIN_LIBNAME.* unconditionally so that their values can
  always be used in other builtin.mk files.

+ In the USE_BUILTIN.* == "yes" case, set BUILDLINK_LIBNAME.* to the
  corresponding BUILTIN_LIBNAME.* value so that BUILDLINK_LIBNAME.*
  can always be used in other buildlink3.mk files.

Define BUILTIN_LIBNAME.* outside of the CHECK_BUILTIN.*-protected
section to be the name of the built-in library if USE_BUILTIN.* is
"yes".  These variables can be used in other builtin.mk files.

+ The termlib.buildlink3.mk file is meant to be included by packages
  that need basic termlib functionality, i.e. tgetent(), tgoto(),
  tputs(), etc.  Together with the termlib.builtin.mk file, they will
  use either a built-in termcap library, a built-in X/Open "enhanced"
  curses library, or ncurses to provide these functions.

+ Add BUILDLINK_LIBNAME.* definitions to the various curses buildlink3.mk
  and builtin.mk files that give the "base" library name of the curses
  library, e.g. curses, ncurses, etc.  These are used by the termlib
  files to set BUILDLINK_LIBNAME.termlib.

Always make ncurses headers and libraries available as <curses.h> and
-lcurses so that GNU configure scripts that check for those ahead of
<ncurses.h> and -lncurses will still use ncurses instead of picking up
a system curses.

This was a regression introduced by my recent ncurses commits.

whitespace

Add fake seed for ncurses.h with NetBSD's curses.

+ Introduce a way for a user to set the default curses implementation
  used by packages that need curses.  From curses.buildlink3.mk:

  CURSES_DEFAULT
	This value represents the type of curses we wish to use on the
	system.  Setting this to "curses" means that the system curses
	implementation is fine.

	Possible: curses, ncurses, pdcurses

+ Move all code to detect a built-in version of curses into a
  curses.builtin.mk file.

+ Add code to {n,pd}curses/buildlink3.mk so make the headers and
  libraries usable as <curses.h> and -lcurses if _PKG_USE_CURSES is
  defined.  _PKG_USE_CURSES is only defined by curses.buildlink3.mk.

+ Improve the detection of native ncurses in ncurses/builtin.mk and
  allow headers and libraries to be usable as <ncurses.h> and -lncurses.

Renamed BUILDLINK_TRANSFORM.* to BUILDLINK_FNAME_TRANSFORM.*, to make
clear that these variables are completely unrelated to
BUILDLINK_TRANSFORM.

Added a legacy check that catches appearances of BUILDLINK_TRANSFORM.*.

XXX: Where should incompatible changes in pkgsrc be documented?

Over 1200 files touched but no revisions bumped :)

RECOMMENDED is removed. It becomes ABI_DEPENDS.

BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.

BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.

BUILDLINK_DEPENDS does not change.

IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".

Added to obsolete.mk checking for IGNORE_RECOMMENDED.

I did not manually go through and fix any aesthetic tab/spacing issues.

I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.

I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.

As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.

As discussed on tech-pkg.

I will commit to revbump, pkglint, pkg_install, createbuildlink separately.

Note that if you use wip, it will fail!  I will commit to pkgsrc-wip
later (within day).

Export BUILDLINK_LDADD.ncurses, which is the flags to link directly
against the curses library used.

Avoid extra stat() calls by not repeatedly checking whether a file
exists on the disk -- we can just check whether a variable defined by
find-files.mk is "__nonexistent__" or not.

Massive cleanup of buildlink3.mk and builtin.mk files in pkgsrc.
Several changes are involved since they are all interrelated.  These
changes affect about 1000 files.

The first major change is rewriting bsd.builtin.mk as well as all of
the builtin.mk files to follow the new example in bsd.builtin.mk.
The loop to include all of the builtin.mk files needed by the package
is moved from bsd.builtin.mk and into bsd.buildlink3.mk.  bsd.builtin.mk
is now included by each of the individual builtin.mk files and provides
some common logic for all of the builtin.mk files.  Currently, this
includes the computation for whether the native or pkgsrc version of
the package is preferred.  This causes USE_BUILTIN.* to be correctly
set when one builtin.mk file includes another.

The second major change is teach the builtin.mk files to consider
files under ${LOCALBASE} to be from pkgsrc-controlled packages.  Most
of the builtin.mk files test for the presence of built-in software by
checking for the existence of certain files, e.g. <pthread.h>, and we
now assume that if that file is under ${LOCALBASE}, then it must be
from pkgsrc.  This modification is a nod toward LOCALBASE=/usr.  The
exceptions to this new check are the X11 distribution packages, which
are handled specially as noted below.

The third major change is providing builtin.mk and version.mk files
for each of the X11 distribution packages in pkgsrc.  The builtin.mk
file can detect whether the native X11 distribution is the same as
the one provided by pkgsrc, and the version.mk file computes the
version of the X11 distribution package, whether it's built-in or not.

The fourth major change is that the buildlink3.mk files for X11 packages
that install parts which are part of X11 distribution packages, e.g.
Xpm, Xcursor, etc., now use imake to query the X11 distribution for
whether the software is already provided by the X11 distribution.
This is more accurate than grepping for a symbol name in the imake
config files.  Using imake required sprinkling various builtin-imake.mk
helper files into pkgsrc directories.  These files are used as input
to imake since imake can't use stdin for that purpose.

The fifth major change is in how packages note that they use X11.
Instead of setting USE_X11, package Makefiles should now include
x11.buildlink3.mk instead.  This causes the X11 package buildlink3
and builtin logic to be executed at the correct place for buildlink3.mk
and builtin.mk files that previously set USE_X11, and fixes packages
that relied on buildlink3.mk files to implicitly note that X11 is
needed.  Package buildlink3.mk should also include x11.buildlink3.mk
when linking against the package libraries requires also linking
against the X11 libraries.  Where it was obvious, redundant inclusions
of x11.buildlink3.mk have been removed.

Create directories before putting files in them.  This should fix
PR pkg/28480.

Reverse the tests so that we actually check for the existence and not
the non-existence of the library -- this more accurately reflects what
we want to say.

Standardize how we search for libraries in builtin.mk files.  We define
_BLNK_LIB_FOUND.<lib> to "yes" or "no" depending on whether -l<lib> is
found in the base system.

Oy, what a hack.  But then, so is Interix....

On Interix, force inclusion of devel/ncurses/buildlink3.mk from
mk/curses.buildlink3.mk.  This forces inclusion of its builtin.mk too.

In devel/ncurses/builtin.mk, if using Interix's builtin ncurses, always
transform -lncurses to -lcurses.  (-lncurses is static, but -lcurses is
shared; we want the shared version.)

Match the template builtin.mk file in bsd.builtin.mk, and make the two
packages that use builtin.mk files (graphics/xpm and pkgtools/x11-links)
use the new format correctly.

Always create the curses.h -> ncurses.h symlink to match buildlink2
behaviour.

Split out the code that deals with checking whether the software is
built-in or not into a separate builtin.mk file.  The code to deal
checking for built-in software is much simpler to deal with in pkgsrc.

The buildlink3.mk file for a package will be of the usual format
regardless of the package, which makes it simpler for packagers to
update a package.

The builtin.mk file for a package must define a single yes/no variable
USE_BUILTIN.<pkg> that is used by bsd.buildlink3.mk to decide whether
to use the built-in software or to use the pkgsrc software.
