nethack/sys/windows/windmain.c
nhmall 92340a6827 consolidate some arg processing 
Unix and Windows had diverged significantly for command line
options handling.

This:
   1. uses the the Unix processing as a baseline.
   2. consolidates the code in earlyarg.c, where it can
      be a common copy to be shared.
   3. start converting the Windows command line argument
      processing to the Unix code that now resides in earlyarg.c.
