[XFS] implement generic xfs_btree_update
From: Dave Chinner <dgc@sgi.com>
The most complicated part here is the lastrec tracking for the alloc
btree. Most logic is in the update_lastrec method which has to do some
hopefully good enough dirty magic to maintain it.
[hch: split out from bigger patch and a rework of the lastrec
logic]
