this lets us get rid of a lot of extra switch statements - in a lot of
places we dispatch on the btree node type, and then the key type, so

Also improve the on disk format versioning stuff.

This is prep work for using deferred btree updates for inode updates -
the way inodes are done now we're relying on btree locking for ei_inode
and ei_update_lock could probably be removed, but it'll actually be
needed when we switch to deferred updates.

ei_update_lock isn't currently needed for write inode (but it will be
needed again when deferred btree updates are used for inode updates)
