Issue 7975: in python 2.6 bsddb.dbshelve switched from DictMixin to
MutableMapping, and thereby lost functionality because the replacement
functionality was implemented incorrectly or incompletely). Since bsddb
isn't in py3k, this patch just goes back to using DictMixin in order to
correct the regression.
