Add a test program for getopt(3) that is adequate for manual testing
and a compact test suite for getopt(3) intended automated regression
testing, both written from scratch.
The suite is intended to provide full coverage, except that it doesn't
test manual changes of optind and optreset and except that it so far
avoids the situation where we have a known bug.
