xfs: introduce rmap btree definitions
Originally-From: Dave Chinner <dchinner@redhat.com> Add new per-ag rmap btree definitions to the per-ag structures. The rmap btree will sit in the empty slots on disk after the free space btrees, and hence form a part of the array of space management btrees. This requires the definition of the btree to be contiguous with the free space btrees.
