Expand __CTRACE() to __nothing #ifndef DEBUG.

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

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

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

overwrite() wasn't copying enough lines or columns.
copywin() couldn't seem to decide whether it should work in window or
screen coordinates - and managed to do neither.
Change copywin() to use window relative coords (as ncurses and solaris do),
and change overwrite() and overlay() to use the modified interface.
It is now possible to use overwrite() to save part of curscr while a
temporary window is drawn.
Fixes PR/26506

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

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

Fix resize of windows with subwins.
Let window size be given as a -ver number => lines from bottom.
Fix trace calls of pointers
(approved by Brett Lumn)

More multiple changes:
* Added function derwin.
* Added function copywin.
* Modified both overlay and overwrite to use copywin.
* Updated man page with new functions and fixed minor format glitch.

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
HEAPS guys!

clean up import

repeat after me: "I hate rcs ids"

update to new version from berkeley. doesn't compile yet, nor
does it have rcsid's. this is for diffs.

New version from uunet.

Add RCS identifiers.

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.
