MFS: two more testcases highlighting recently discovered problem with version
comparison routine.

Fix a problem with tests of the form "1.0" vs. "1.0a".
MFC candidate.

Pointed out by: knu

Implement a package number comparison routine for pkg_version(1)
that actually conforms to the Porters Handbook.

Add a -t option to pkg_version(1) for doing comparison testing.

Add a script (and make test target) to do some regression tests on
the package number comparison routine, to help debug future revisions.
