Fix for install/56467

Set x to 0 before calling scroll based on a  proposed fix by RVP (thanks!)
Update check files affected by a fix to addbyte.c in libcurses.

Correct the fd closed check so we actually check the outfd as per
the comment.  Thanks for jdc%netbsd.org@localhost for catching this one.

Expand __CTRACE() to __nothing #ifndef DEBUG.

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

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

Sync with HEAD

Sync with HEAD, resolve a couple of conflicts

Fix for PR lib/52063
Many thanks to  Onno van der Linden (o.vd.linden@quicknet.nl) for providing
the bulk of the patch that fixes the issue.

curses: don't optimize stdout buffer for non BSD platforms

The way BSD setvbuf works is not portable and should not be relied on.
This is only important if curses is started, stopped and started in the
same session which is how portable applications handle terminal resizing.

Sync with HEAD.  (Note that most of these changes are simply $NetBSD$
tag issues.)

KNF.
Normalise coding style.
White space police.
Sprinkle some extra braces to make the flow more clear.

No functional changes.

Implement POSIX Curses typeahead function.

fix placement of lint comment

Fix for systems that don't have TCSASOFT as intended originally. Simplify.

Userland now builds and uses terminfo instead of termcap.

OK: core@, jdc@

Move calls to __restore_termios() into the failing path of the functions
that fail - instead of in most of the callers.
All rather pointless if tcsetattr() fails to set the mode we want we
are very unlikely to be able to restore any later on.

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

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.

Add some more debugging information.

Add some more debugging information.

PR/34011: Julian Coleman: Limit timeout to 25.5 seconds.

Add function descriptions. From Douwe Kiela.

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

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

Adjust layut to put ?: clause on a single line

Add noqiflush() and qiflush()
Fixes PR lib/20037.

Apply patch (requested by jdc in ticket #1244):

Keep the cr->nl translation state in a separate variable, so that we can
do the translation ourselves (if the tty didn't do it for us).
Add debugging to track functions that change tty state.

Keep the cr->nl translation state in a separate variable, so that we can
do the translation ourselves (if the tty didn't do it for us).
Add debugging to track functions that change tty state.

Fixes PR 20834 by Stephen Borrill.

Let's call it 'duration' instead of 'timeout' so that the compiler is happy.

Added halfdelay() function.

handle non-tty cases more gracefully.

Remove extraneous tabs from blank lines.

fix __startwin() so it outputs the init strings to the correct device.

lib/14813: Jason R. Thorpe: worm(6) no longer builds w/ new libcurses
Make baudrate a function, gc old variables, implement ospeed in terms of
baudrate, bump major number to 5, since we don't have __baset anymore.

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

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.

Really fix the __endwin/stop handler problem.

Move setting of __endwin so that we also change it from the stop handler.

Use __restartwin() in reset_prog_mode() and __stopwin() in
reset_shell_mode().

Send, if necessary, 'ks' or 'ke' sequences from keypad() and wgetch().
Fixes PR 10116.

* Made erasechar and killchar into functions
* Modified __init_getch to use termcap handle that has been allocated
  (_cursesi_genbuf) instead of refetching it.
* Make wgetstr support erase - this is not a full blown SUSv2 version
  but it is a start.

No, really, make sure ECHO is cleared in cbreak() mode too.

Don't fiddle with the tty echo state in echo() and noecho(); it should always
remain off.

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 intrflush().
Add def_shell_mode() and reset_shell_mode().
Include private header.

Made data structures opaque

Use fpurge() in flushinp().

Changes to make libcurses SUS v2 compatible.

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!

Pull rev 1.9 up from trunk (phil)

Changes to make endwin() act like a SIGSTP in terms of nicely restarting
curses mode.  Taken from e-mail about PR 3981.  (Still some stuff left
in PR3981 to deal with.)

Make endwin() save state so a subsequent call to wrefresh restores curses
and makes endwin()/wrefresh() act like a SIGTSTP.
