curses: use perror rather than err in initscr

libhack lacks err and perror is more portable.

curses: application should exit if initscr(3) fails

POSIX defines this behaviour here:

curses: fix ripoffline

When creating stdscr, ensure it's placed and sized in accordance with
lines ripped off.
LINES is no longer adjusted for lines ripped off.
POSIX makes no mention that it should be adjusted.
Bottom lines are now placed correctly.
Lines ripped off are now displayed after calling initscr.

Pull down the following from the wcurses branch:
ctrace.c: revision 1.16.2.2
initscr.c: revision 1.27.18.2
Orginal commit message:

Do the debug initialisation only in ctrace.c. Otherwise, it might not
get done, for example, if we start curses with setterm() and not initscr().

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: 1.27.18;
We no longer need <signal.h>.

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 :-(

ARemove (no longer used) __nca.

Remove extraneous tabs from blank lines.

* Major change to add support for the newterm/set_term functions.
* Added fix to getch.c suggested by Gabriel Rosenkoetter (thanks :-)

de-lint:
- bad arithmetic shift
- const castaways.

Rename variables refering to termcap capabilities from NN to __tc_nn. Case
adjusted to match termcap capability. A few other variable names renamed too
(ones related to or derived from termcap variables).

Move setting of __endwin so that we also change it from the stop handler.

branches: 1.18.2;
* Made erasechar and killchar into functions
* Modified __init_getch to use termcap handle that has been allocated
(_cursesi_genbuf) instead of refetching it.
* Make wgetstr support erase - this is not a full blown SUSv2 version
but it is a start.

Add virtual screen for wnoutrefresh()/doupdate().

Multiple fixes:
* Added Bill's fixes for errors when compiling with WARNS=1
* Incorporated fixes to make usage of unctrl consistent in debug and
made improvements to ctrace - it now timestamps it's output better.
* Reduced the number of mallocs done by __init_getch by allocating key
structs in bunches instead of singly.
* Removed the shadowing of global declarations in newwin and subwin
functions

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.

Add a list of windows (used when a colour pair changes).

Initialise colour variable (__nca).
Include private header.

Made data structures opaque

branches: 1.11.6;
Get rid of the evil trailing spaces and tabs.

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
