Fixes for lib/56926 amongst other things:
- plod now correctly accounts for wide characters when plodding
- use erase line when in color mode if the terminal has the capability
- ensure that the CA_CONTINUATION flag is applied consistently to the
subsequent characters in a wide character.
- fix a bunch of refresh bugs that caused inconsistent placement of
wide characters.

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

Correct (hopefully) the handling of wide characters.

* Remove the WCOL family of macros, these were "stealing" the upper bits
of a character attribute to store the column width of a character. No
warning was given about this in curses.h which meant it was easy to
accidentally reuse the bits in use by the WCOL macros (we already did).
Add couple of 16bit ints to the character structure iff HAVE_WCHAR is
true to hold the display width and wide char related flags (just
continuation at the moment)
* Convert all instances of WCOL macros to just reference the column width
in the char structure so it is not obfuscated.
* Fix cursor positioning so placing a cursor in the middle of a wide char
actually does just that.
* Fix plod so it understands that if the cursor is going to be positioned
in the middle of a wide char it cannot just reprint the char to get there.
* Fix plodput so it correctly counts the number of output characters for
wide characters.
* Fix slk routines to properly size the wctomb() buffer.

Hopefully unbreaks !DEBUG builds.

Fix for PR lib/55433

Correct the behaviour for ins_wstr:
* Properly check the string will fit by processing any special
characters present when preforming the check.
* Simplify the routine by removing code that duplicates the code in
_cursesi_addwchar and just call _cursesi_addwchar.

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

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

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.

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.

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.

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

Implement POSIX Curses functions immedok(3) and syncok(3).

remove bogus malloc casts

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

Observe the following spelling:
- wide character (noun)
- wide-character (adjective)

misc fixes and improvements:
-call setlocale(LC_CTYPE, "") before nl_langinfo(CODESET) if the
locale settings is (still) at "C" - otherwise the CODESET doesn't work
-fix the type of the WACS_* symbols -- this needs to be cchar_t*
-add safeguards where the return value of wcwidth() is used for
loop counters or indexing -- it can be -1
-use more common code in the widechar support case -- in particular
let the wchar functions do the work even if chtype ones were called
-implement wcursyncup/wsyncup/wsyncdown
-somewhat experimental: allow ACS_* variables to refer to WACS_*
table entries -- this way, programs using the old chtype using API
can use UTF8 line drawing on terminals which support UTF8 but not
ACS switching
-fix some logics bugs in UTF8 recognition and ALTCHARSET handling

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.
