Fix return for mvscanw to return ERR/OK instead of the number of
elements scanned, now matches SUSv2 specification

Bump lib major due to return change.

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

No functional changes.

branches: 1.21.24;
Retire varargs.h support. Move machine/stdarg.h logic into MI
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.

Add vw_printw and vw_scanw as mandated by SUSv2's xcurses. Follow
ncurses and just make the historic vwprintw and vwscanw functions
aliases, ignoring that they should take a varargs.h va_list argument.

Fix some compiler warnings.
Remove shadowed variable declarations when DEBUG is defined.

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

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

PR/17352: David Laight: Curses core-dumps on windows > 1024 wide.

__STDC__ is always defined on NetBSD.

va_list -> _BSD_VA_LIST_ to be consistent with prototype
(doesn't compile on sparc64 otherwise)

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.

Don't wrap declarations of mvwprintw & mvwscanw.

Restore const after the Open Group decided it was OK.
Thanks due to Brett Lymn.

Made data structures opaque

branches: 1.10.6;
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!
