xfs: split out on-disk transaction definitions
There's a bunch of definitions in xfs_trans.h that define on-disk formats - transaction headers that get written into the log, log item type definitions, etc. Split out everything into a separate file so that all which remains in xfs_trans.h are kernel only definitions. Also, remove the duplicate magic number definitions for XFS_TRANS_MAGIC...
