[XFS] kill struct xfs_btree_hdr

Browse Source 
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.
