Marcelo Matus 55005e98ee Move rename/namewarn engine from parser.y to naming.c. The code was getting
too large to be in the parser.

Centralize the swig keys to avoid replication and wrong spellings.

Use more HashGetAttr where possible and other speed improvements
to compensate for the extra work introduced by the new rename/namewarn
mechanism.
