Remove optreset from src/port/ implementations of getopt and getopt_long.

Browse Source 
We don't actually need optreset, because we can easily fix the code to
ensure that it's cleanly restartable after having completed a scan over the
argv array; which is the only case we need to restart in.  Getting rid of
it avoids a class of interactions with the system libraries and allows
reversion of my change of yesterday in postmaster.c and postgres.c.

Back-patch to 8.4.  Before that the getopt code was a bit different anyway.
