xfs: merge xfs_lrw.c into xfs_file.c
Currently the code to implement the file operations is split over
two small files. Merge the content of xfs_lrw.c into xfs_file.c to
have it in one place. Note that I haven't done various cleanups
that are possible after this yet, they will follow in the next
patch. Also the function xfs_dev_is_read_only which was in
xfs_lrw.c before really doesn't fit in here at all and was moved to
xfs_mount.c.
