Allow sys/share/random.c to be included in the build
always, even if USE_ISAAC64 is defined, by making most
of its contents conditional in that case.
That avoids Makefile tinkering when going back and
forth between USE_ISAAC64 and not during testing.
Since no one has come up with a better fix for has_colors() being
implicitly declared, add a hack for suppressing a compiler complaint
about has_colors() on linux and/or sco unix that use sufficiently old
<curses.h>.
Report was right after release of 3.6.0 but my fix at the time broke
compile when using more recent <curses.h>.
Windows build was actually only using a single function
in there, so just add a similar function to sys/winnt/winnt.c
and eliminate the need for including sys/share/pcsys.c in
the build.

Because multiple window ports are supported on Windows
now, even in the same executable and selectable via
config file in some cases, some adjustments became
necessary. There will likely be some further refining
of this over the next day or two.
List of changes:
Move Windows startup from sys/share/pcmain.c and
into its own sys/winnt/windmain.c so that it can
be modified to fix some current breakage, and
allow altering the order of some things.
There is startup processing code that is common to
all of the Windows WindowPorts, but that startup
processing code needs to have no dependency on
any one of those WindowPorts.
Yet, during startup processing, some of the initialization
routines can end up calling NetHack functions that
expect an active Window port underneath, and if there
isn't one, routines like pline, impossible, panic can
end up invoking null function pointers.
Place a new file sys/share/safeproc.c, in which a complete
window port is available for early startup processing
purposes. It's WindowPort name field is set to
"safe-startup" just for reference. The prototypes in
include/winprocs.h require that SAFEPROCS be
Usage:
windowprocs = get_safe_procs(0);
initializes a set of winprocs function pointers that ensure
none of the function pointers are left null, but that's all it does.
windowprocs = get_safe_procs(1);
initializes a set of winprocs functions pointers that ensure
none of the function pointers are left null, but also
provides some basic output and input functionality using nothing
other than C stdio routines (no platform or OS specific code).
The conditional code related to WIN32 has been removed from
sys/share/pcmain.c
The code common to all of the Windows WindowPorts calls
get_safe_procs() almost immediately to ensure that
there is a set of WindowPort winprocs available.
The Windows graphical version in NetHackW.exe is meant to lock
itself to its own windowtype and ignore the OPTIONS=windowtype
setting in the config file, but the code to perform the lock
only did so if (argc > 1).
Moved the code page 437 mapping table to winnt.c so that it could be
used in window and console clients.
Added check that fonts support unicode values we use from code page 437.
Use unicode to draw text if font supports it otherwise use ASCII.
When dgn_comp.l and lev_comp.l are processed by older versions of
flex, 'gcc -Wunused' complains when compiling dgn_lex.c and lev_lex.c
because flex creates 'static void yyunput()' and nethack doesn't use
it. Newer versions honor macro YY_NO_UNPUT to hide the offending
code, but that doesn't help with older versions (like the one
masquerading as 'lex' on OSX). Adding a dummy usage would probably
cause problems with other lexers, so change it from static to
'void yyunput()' as a 'sed' fixup in util/Makefile after flex has
finished. That will be a no-op when yyunput doesn't exist or isn't
static.
In addition to the sys/unix/Makefile.utl change, this checks in new
sys/share/{dgn,lev}_lex.c with the fixup in place.
