- Fix bsddb.dbtables: Don't randomly corrupt newly inserted rows by
   picking a rowid string with null bytes in it.  Such rows could not
   later be deleted, modified or individually selected.  Existing
   bsdTableDb databases created with such rows are out of luck.
 - Use mkdtemp for the test_dbtables test database environment and
   clean it up afterwards using shutil.rmtree.

Fixes http://bugs.python.org/issue1233 - bsddb.dbshelve.DBShelf.append
was useless due to inverted logic.  Also adds a test case for RECNO dbs
to test_dbshelve.

This code was broken if save() returned a negative number since i contained
a boolean value and then we compared i < 0 which should never be true.
