Summary: iterator for dbm keys

Initial Comment:
if d is a dbm (gdbm, bsddb, shelve, etc.) object, then
"for k in d"
should iterate through the keys of d, like you can do
with dicts.  Alternatively, add a new operation,
d.xkeys(), which returns an iterator that steps through
all the keys in d.  d.keys() is often inappropriate
since dbm databases can be extremely large and d.keys()
tries to read all the keys into memory at once.
