Add a test program for getopt(3) that is adequate for manual testing

and a compact test suite for getopt(3) intended automated regression

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.
