Expand __CTRACE() to __nothing #ifndef DEBUG.

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

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

printw: rework vw_printw so it uses open_memstream rather than funopen2

This makes it more portable as open_memstream is POSIX and fixes a
potential issue with wide characters not fully being printed
due to any buffer overflow.

branches: 1.20.14;
KNF.
Normalise coding style.
White space police.
Sprinkle some extra braces to make the flow more clear.

No functional changes.

It is expensive to open and close files for every printf, keep it around.

branches: 1.18.8;
Note that delwin(3) is a null-op if win is NULL.

branches: 1.17.6; 1.17.12;
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.

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

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

branches: 1.14.4;
When deleting windows and screens, also set to NULL the standard names
that refer to the window or screen just deleted.
Add some more debugging information.

branches: 1.13.6; 1.13.12;
Move UCB-licensed code from 4-clause to 3-clause licence.

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

Remove __winlistp, add *screen to WINDOW and initialise in newwin().
Make delwin() remove window from list of windows on its screen.
Free win->lspace and win->lines for subwins (they only share text space).
Free things in the correct (and same) order if malloc() fails in __makenew().
Adjust delscreen() for delwin() removing itself from winlist.
Fixes potential massive corruptions if delwin() called on a main window.
NB: not responsible for the sysinst core dumps :-(

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.

Made data structures opaque

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
