removed some HAVE_* symbols from msdos/*.inp, nt/config.nt, src/s/ms-w32.h

[Paul Eggert]

I installed the following further cleanup of unused symbols,
along with the corresponding routine removals from the
MS-DOS / NT / W32 files.

Come to think of it, these cleanup changes to the MS-DOS / NT / W32 files
are not strictly needed -- Emacs should build fine without them --
so it sounds like I should omit them in the future.  That'd be safer, and
less work for me, and Eli can batch the corresponding Windows cleanups if and 
when
it's convenient.  Of course there will be other configure-ish changes that
do require immediate updates to MS-DOS / NT / W32 files, but these
can remain higher priority.
