C++-ify typedef hash

This changes the typedef_hash_table structure to be a C++ class.  It
adds constructors and destructors and changes some functions to be
methods of the class.  Then it changes the various users of this class
to adapt.  This allows for the removal of some cleanups.

Regression tested by the buildbot.
