dm persistent data: support space map resizing Support extending a dm persistent data metadata space map. The extend itself is implemented by switching back to the boostrap allocator and pointing to the new space. The extra bitmap indexes are then allocated from the new space, and finally we switch back to the proper space map ops and tweak the reference counts.
