[csw-maintainers] checkpkg updates

[Maciej (Matchek) Blizinski]

I spent some more time on checkpkg today.  I removed almost all the
checks from the Korn code and ported them to Python.  I also ported
all the Python checks to the new API.

All the checks are now in this file:
https://sourceforge.net/apps/trac/gar/browser/csw/mgar/gar/v2/lib/python/package_checks.py

The output will be now less verbose, and checkpkg will now run slightly faster.

As always, please report any failures you might encounter.
