Subject: add compat getopt implementation, remove patches

This adds a getopt implementation for compatibility where it is not
available, removing a couple of regress patches.

Note, this is a slightly modified copy from OpenBSD libc that doesn't
expose getopt_long, which has dependency conflicts with Windows system
headers and isn't needed anyway.
