Bug description:  Revisit locking in DBA for DB4

Description:
------------
The locking for DBA with DB4 needs to be revisited.

The way DB_INIT_LOCK and DB_FCNTL_LOCKING are passed to DB4, and
the use of DBA_LOCK_EXT in dba.c seem to be based on the assumption
that BDB will do locking.  This isn't true with the way BDB is used by
DBA.

See http://bugs.php.net/bug.php?id=45266 for why DB_INIT_LOCK isn't
valid.  DB_FCNTL_LOCKING is undocumented.  It implies that PHP does
locking. It just tells BDB when to release file handles.

Perhaps the easiest solution is for dba.c to use DBA_LOCK_ALL, but
I'm not fully aware of the implications of this flag.
