net/py-libnet: Update to 3.0rc1, Remove/fix BROKEN_*
Switch port to use autoplist to preclude having to manually
construct shared library names based on ARCH/uname manipulations.
While I'm here:
- Switch to latest upstream release: 3.0rc1, via CHEESESHOP
- Remove patch that was fixed upstream 
- Match COMMENT to setup.py:description
- Strip shared library

powerpc64/mmu: Make moea64_pvo_enter() return if an entry already exists
Instead of searching for a PVO entry before adding, take advantage of
the fact that RB_INSERT() returns NULL if it inserts, and the existing entry if
an entry exists, without inserting a new entry. This saves an extra tree
traversal in the cases where the PVO does not exist.
