Keyword substitution: kv
Default branch: MAIN

Sprinkle about some cycle wasting checks for the win pointer being
null.  Unfortunately, ncurses does this and there is some sloppy code
out there that relies on the check resulting in segfaults in
NetBSD curses which then, of course, gets blamed for the error.

Make the default colour pair be pair 0 which appears to match other
curses implementations.

Expand __CTRACE() to __nothing #ifndef DEBUG.

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

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

libcurses: fix usage of __warn_references

Since that macro can expand to an empty token list, it adds its own
semicolon as needed.  Removing the extra semicolon fixes the lint
warnings about empty declarations.  These empty declarations are a GCC
extension.

Rework previous fix for getch cursor position when cursor is moved
without refresh.  If the window is not dirty but the window cursor
position does not match curscr then move the cursor.  This fixes
the issues seen in PR lib/54263.

Back out incorrect fix for PR 53617 and fix it in a different way.
Keep track of the cursor location, if getch is called without a refresh
and without pending updates (dirty windows) then move the cursor to the
correct location directly.  Doing this prevents unnecessary refreshes.

Fix warn macro usage.

Thanks to rofl0r.

Sync with HEAD, resolve a couple of conflicts

Drop HAVE_WCHAR ifdefs from code that is not even compiled with !HAVE_WCHAR.

We still try to mainain the ability to build our curses with
!HAVE_WCHAR, but it doesn't make sense to provide stubs for new wide
API functions that just error out when !HAVE_WCHAR.  Any code that
only uses old API (and can work with !HAVE_WCHAR curses) doesn't use
those new functions.  The code that uses new API obviosly cannot work
when all the new API is stubbed out.

So the plan is to drop the stubs.  This commit does that for files
that are not even compiled with !HAVE_WCHAR (not only those stubs are
useless, they were not even there to begin with).

Same object code is generated for the normal HAVE_WCHAR case.  Nothing
is even recompiled for !HAVE_WCHAR.

Ok by blymn@ jdc@ roy@

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.

Make this compile when HAVE_WCHAR is not defined.

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

 * rearrange code to ensure that SET_WCOL() is called after attributes
   are copied/set.

 * fix some instances where attributes were being checked without
   masking with WA_ATTRIBUTES

 * Replace another instance of non-spacing character copying with function
   call.

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.

Merge wide curses.
