curses: constify newterm() and setterm() arguments

newterm() argument is const in the spec, so this fixes our
conformance.

setterm() is not in the spec, but it's natural and in ncurses its
argument is const too, so follow suit.

Doesn't change the ABI, so no bump required.

ok blymn@

Style fixes most for __CTRACE().

Expand __CTRACE() to __nothing #ifndef DEBUG.

Remove most of #ifdef DEBUG around __CTRACE() calls.

No binary changes, except for line numbers for assert().

Add missing newline to debug trace message

curses: fix ripoffline

When creating stdscr, ensure it's placed and sized in accordance with
lines ripped off.

LINES is no longer adjusted for lines ripped off.
POSIX makes no mention that it should be adjusted.
Bottom lines are now placed correctly.
Lines ripped off are now displayed after calling initscr.

POSIX says that use_env(3) must precede setupterm(3).
The former lives in curses.h, but the latter lives in term.h.

This is solved by moving the function to libterminfo.
Because the environment can affect the terminal capabilities for
lines and columns, it follows that the tty size should affect it to.
So move that code to libterminfo and adjust in libcurses.

Make this compile again (gcc does not like strcmp(maybe-NULL, maybe-NULL);
simplify the life of the {compiler,human eyes}.

Move ESCDELAY to curses.c so all globals are close to each other.
Remove _reentrant and use ESCDELAY and TABSIZE as we're not really
reentrant.

Check _cursesi_term is set in a few places and sprinkle some static.

If either set_escdelay(3) or set_tabsize(3) are called, set _reentrant
to ensure we use the saved value for the sceen.

This effectively makes ESCDELAY and TABSIZE read-only when either
of these functions are called.

Move the ripoffline logic out of screen.c and into ripoffline.c.
Store ripped off lines in the SCREEN structure so we can repaint then
when the terminal is resized.
Fix mvwin(3) so it can move windows in the ripped off area.

Implement POSIX curses function ripoffline(3).

for a reference, the tree before this commit was tagged

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Add TABSIZE, which is derived from terminfo init_tabs.
Use this when processing \t.
If TABSIZE is set in the environment, this takes precedence.

	lib/libcurses/setterm.c: revision 1.51
Fix a NULL dereference if the exit_alt_charset_mode capability is not
defined.
The previous version of this file changed a terminal initialisation test on
the exit_attribute_mode capability, checking for the exit_alt_charset_mode
capability as a substring, rather than performing a search for the
hard-coded
^O character.
That works better on terminals where ^O is not the correct value for
exit_alt_charset_mode.  But it works worse on terminals that don't have a
definition specified for exit_alt_charset_mode.
For example:
% TERMCAP='xterm:me=\E[m:' TERM=xterm vi
segmentation fault (core dumped)  TERMCAP='xterm:me=\E[m:' TERM=xterm vi
The crash can be avoided (without fixing the bug) by defining
exit_alt_charset_mode:
% TERMCAP='xterm|:me=\E[m:ae=:' TERM=xterm vi
ex/vi: Error: xterm: No such process
We now test exit_alt_charset_mode for NULL before continuing with the fatal
test, restoring the original no-crash behaviour.
XXX does_ctrl_o() is now just a naive reimplementation of strstr(), so
should
probably just use strstr() instead.

Add capfile(5) to describe the termcap format.
Adjust various man pages and other documentation to point to capfile(5)
instead of termcap(5).
Remove getcap(3) as curses hasn't been building it for a long time.
Punt wrterm.c as tset no longer uses it.

Move longname(3) from curses to terminfo, pre-cursor to fix PR/43386.

Don't assume the terminal has a description.

Userland now builds and uses terminfo instead of termcap.

OK: core@, jdc@

Prepare curses for the possibility of changing from termcap to terminfo.
term.h #defines lines, pad_char and no_color_video macros which conflict
with existing curses code. We change lines to alines and nlines depending
on use, pad_char to padchar and no_color_video becomes no_color_attributes
but with a strong alias from no_color_video.

Make it build without HAVE_WCHAR

We don't need separate #ifdef's for __ALTCHARSET and WA_ALTCHARSET, as they
are defined to be the same in curses.h.

Merge in wide curses code done as a Summer of Code project by
Ruibiao Qiu.

Change debug code slightly, so that it doesn't confuse __CTRACE().

Apply the changes that add debug "areas" on HEAD to the wcurses branch.
Add correspending changes to the debug code that is only present on the branch.

Add debug "areas" that allow selective debugging by setting the
"CURSES_TRACE_MASK" environment variable.  Postive vales include
debug areas, negative values exclude them.

Pull up revision 1.39 (requested by blymn in ticket #716):

Don't compare a char to NULL.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22280, verified by myself.

Redo the conflict calculation (again).
Assume that "me" clears all attributes apart from acs.
Problem noticed when working on window(1).

Change the way we calculate conflicts when turning off attributes.
We now check the termcap entries for "\E[m" or "\E[0m" or a longer
"\E[ ... m" sequence containing a "0".

Set LINES and COLS here so that __swflags() sets flags on the initial windows.
Remove no longer useful debug output.

Add a hack for xterm-like terminals where "\E[m" will turn off
other attributes.

PR/17352: David Laight: Curses core-dumps on windows > 1024 wide.

Remove extraneous tabs from blank lines.

 * Remove termcap globals from public interface
 * Clean up commented out code

* Major change to add support for the newterm/set_term functions.
* Added fix to getch.c suggested by Gabriel Rosenkoetter (thanks :-)

Revert the change to the `pc' capability from the previous change.  Pointed
out in email by Thomas Dickey.

Rename variables refering to termcap capabilities from NN to __tc_nn.  Case
adjusted to match termcap capability.  A few other variable names renamed too
(ones related to or derived from termcap variables).

Sync w/ netbsd-1-5-base.

Restore changes 1.23->1.24 that were accidently overwritten.

Make sure tspace is large enough to hold all capabilities.

Fix broken getcap call - it was always returning NULL.  Thanks Itojun
for spotting this one!

We already initialize UP and BC when we fire up Curses, so pass a null pointer
to t_goto() to avoid doing it again... and again... and...

Fix pasto.

Speed up refresh in the presence of attributes by precalculating a mask for
each `end' command to turn off other attributes in the case of conflicts.

Background colour erase is 'ut' not 'be'.

* Fixed need for duplicate namp string in setterm.c
* Added meta function (turns meta bit on and off on terminal if supported)
* Added curs_set to control cursor visibility if supported.

Converted all termcap library calls to the "new" interface, this fixes
a problem with curses crashing when the CM capability was larger than
64 bytes and eliminates some possible buffer overflow problems.

Multiple fixes:
* Added Bill's fixes for errors when compiling with WARNS=1
* Incorporated fixes to make usage of unctrl consistent in debug and
  made improvements to ctrace - it now timestamps it's output better.
* Reduced the number of mallocs done by __init_getch by allocating key
  structs in bunches instead of singly.
* Removed the shadowing of global declarations in newwin and subwin
  functions

Added functions to replace what were previously macros in curses.h
(this is a requirement of SUSv2) - the old macro behaviour can be
restored by defining _CURSES_USE_MACROS.
Changed function prototypes to use ANSI style.
All externally visible functions now have ANSI style declarations.

Add colour capabilities.
Increase size of attribute buffers.
Include private header.

Made data structures opaque

Add alternate character set support.

Changes to make libcurses SUS v2 compatible.

Pull up to last week's -current.

Another unctrl() %s fix.

Get rid of the evil trailing spaces and tabs.

Upgrades the standard NetBSD curses library to provide some
of the SYSV curses facilities.  The added features are the collapsing
of arrow and function keysequences (as defined by termcap for the
terminal) into symbolic code returns thus relieving the application of
recognising multi-character key sequences.  Other features are the
capability to perform a timed wait for a key (good for when you are
not sure if there is a keypress ready or not) and the capability for
turning off the inter-key timeout when assembling multi-character
function keys.

this work was done by Julian Coleman <J.D.Coleman@newcastle.ac.uk>
and blymn@baea.com.au (Brett Lymn).  i'm just integrating it.  thanks
HEAPS guys!
