SF patch  [ 545523 ] patch for 514433 bsddb.dbopen (NULL)
closes SF #514433

can now pass 'None' as the filename for the bsddb.*open functions,
and you'll get an in-memory temporary store.

docs are ripped out of the bsddb dbopen man page. Fred may want to
clean them up.

Considering this for 2.2, but not 2.1.
