can use the dav_hooks_locks_generic structure to implement locking in a
non-optimal, but compliant fashion. (Use 'dav-lock', 'generic', '0' to
ap_lookup_provider to retrieve it.)
Use the DavGenericLockDB directive to configure the location of the lock
database (may be server-relative or absolute).
This allows all DAV providers to use a baseline locking API rather than roll
their own.
This code is based mainly off the mod_dav_fs locking code (which uses the
on-disk storage for locking), but removing components that aren't needed in a
non-file-backed repository (such as recording inodes).
