Revert revision 4550.  As Greg Stein notes:

   We return hash tables in several places. But those hash tables
   should be mapped into Python dictionaries, rather than left as raw
   hash tables.

   For example, see the code in svn_client.i to process the return
   values for svn_client_status() and svn_client_ls().
