Subject: Rename the extension registry variables to have leading underscores
 -- this clarifies that they are part of an internal API (albeit shared
 between pickle.py, copy_reg.py and cPickle.c).

I'd like to do the same for copy_reg.dispatch_table, but worry that it
might be used by existing code.  This risk doesn't exist for the
extension registry.
