[issue6045] Fix dbm interfaces

Christopher Lee added the comment: I suspect that for most users, shelve is the main way they will access the dbm.* interfaces. Based on that, the dict methods that are really needed on dbm.* objects are just: __iter__, __len__, __getitem__, __setitem__, __delitem__, __contains__, has_key, and

[issue6045] Fix dbm interfaces

New submission from Georg Brandl : All the dbm.* modules currently have different interfaces, and different levels of supporting the Python3-style dictionary interface -- while the docs claim they all have (most of) the dict interface. For example, both dbm.gnu and dbm.ndbm only have keys() meth
