[RFC] lang/python30 (and lang/python*) fixes

[Li-Wen Hsu]

Hi all,

After reviewing python31 port and freebsd-python's PRs,
I propose this patch for lang/python30:

http://people.freebsd.org/~lwhsu/python30.diff

Changes are:

- Honor EXAMPLESDIR, DATADIR and NOPORTEXAMPLES, NOPORTDATA
- Remove bsddb module in pkg-message since it's removed from
  Python default modules
  (python3 user should use databases/py-bsddb3)
- Fix WITH_UCS4 support (ports/133440)
- Mark jobs safe
- Makefile cleanup

If nobody objects, I'll commit it after 24 hours.

For python31, shar is updated at the same place:

http://people.freebsd.org/~lwhsu/bsd.python.mk-python31.diff
http://people.freebsd.org/~lwhsu/python31.shar

For python2*, I'll update them after patches for python3* committed
(of course if nobody objects)
and probably include tmclaugh@'s patch in ports/109550 for python*.  I
think this matches
what bsd.python.mk does.
