[XFS] kill struct xfs_btree_hdr
This type is only embedded in struct xfs_btree_block and never used directly. By moving the fields directly into struct xfs_btree_block a lot of the macros for struct xfs_btree_sblock and struct xfs_btree_lblock can be used for struct xfs_btree_block too now which helps greatly with some of the migrations during implementing the generic btree code.
