blymn ee6c5161ec 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.

blymn a7d2c21606 * Don't redraw the background if the new background character is the
same as the old one.  This prevents excessive redraws in some
   applications.

 * Fix bug introduced when wbkgrndset was fixed, we cannot blindly
   replace any instance of the old background character with the new one
   because some of those characters were put there by the application
   leading to display corruption.  So flag characters as background when
   they are erased and only update the flagged characters when setting
   the background.

blymn 301bf8cc44 Make the default colour pair be pair 0 which appears to match other
curses implementations.

blymn f1942931a2 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.

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

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

blymn 2a780e62ed 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.

blymn e2cfd49c61 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.

roy 43d5eb454b 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.

problem (reported by David Bariod on netbsd-help), where erasing an already

blymn aaf74682b9 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.

mrg 586d4ce109 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!

alm 75de25bb93 added Andrew Chernov's patch set:
Standard curses library use eight bit for standout mode, so
8-bit characters displays like highlighted 7-bit characters.

This patch produce library which is fully compatible with all curses
programs and add 8-bit chars to all input/display functions.
---
I don't think, that any programs wish to use internal curses
attribute _STANDOUT directly, in expressions like:
        addch( ch | _STANDOUT );
        Normal interface use standout() and standend() functions instead.
        Many programs use 'char' type (with sign extention) for input characters
        and sign extention becomes _STANDOUT mode in this case.
        So, I refuse this future and allow 8-bit characters for programs,
        which is designed for 7-bit only ('char' type using instead of
        'unsigned char').
---
This small patch fix unpleasant standard curses bug:
curses can't expand TAB at all (but tries).
A man who wrote this curses misplace SYNC_IN and SYNCH_OUT,
this patch exchange macro calls.

This patch useful for standard 7-bit curses too, for this
you must delete '_' symbol before waddbytes and apply patch.
---
Oh, NO! This curses are really buggy!

This small patch fix following problem:
[ assumed scrollok(stdscr, TRUE) ]
when addch(ch) at lower right corner of screen, curses are realy
gone mad instead if simple scrolling... Curses code assumed that
this will be done correctly, but implement it with two bugs.
