[XFS] move xfssyncd code to xfs_sync.c

Move all the xfssyncd code to the new xfs_sync.c file. This places it
closer to the actual code that it interacts with, rather than just being
associated with high level VFS code.

- * When remounting a filesystem read-only or freezing the filesystem,

- * inodes out after we've waited for all the transactions created by

- * to ensure that the inodes are written to their location on disk

- * after a quiesce there is no log replay required to write the inodes
- * to disk (this is the main difference between a sync and a quiesce).
