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.
