Joe Thornber	f164e6900f	dm btree: add dm_btree_find_lowest_key ... dm_btree_find_lowest_key is the reciprocal of dm_btree_find_highest_key. Factor out common code for dm_btree_find_{highest,lowest}_key. dm_btree_find_lowest_key is needed for an upcoming DM target, as such it is best to get this interface in place.

Joe Thornber	3241b1d3e0	dm: add persistent data library ... The persistent-data library offers a re-usable framework for the storage and management of on-disk metadata in device-mapper targets. It's used by the thin-provisioning target in the next patch and in an upcoming hierarchical storage target.
