Sprinkle about some cycle wasting checks for the win pointer being
null.  Unfortunately, ncurses does this and there is some sloppy code
out there that relies on the check resulting in segfaults in
NetBSD curses which then, of course, gets blamed for the error.

Do not compile in whole fileio.c for LIBHACK.

Fix build failure when built as libhack, due to missing fileio.h.

IMO, this should be cleaner than generating fileio.h for {get,put}win(3),
that are useless for install media.

Expand __CTRACE() to __nothing #ifndef DEBUG.

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

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

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.

remove bogus malloc casts

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.
