drop linux/ufs_fs.h from userspace export and relocate it to fs/ufs/ufs_fs.h

Per previous discussions about cleaning up ufs_fs.h, people just want
this straight up dropped from userspace export.  The only remaining
consumer (silo) has been fixed a while ago to not rely on this header.
This allows use to move it completely from include/linux/ to fs/ufs/
seeing as how the only in-kernel consumer is fs/ufs/.

- * Each disk drive contains some number of filesystems.
- * A filesystem consists of a number of cylinder groups.
- * Each cylinder group has inodes and data.
- *
- * A filesystem is described by its super-block, which in turn
- * describes the cylinder groups.  The super-block is critical
- * data and is replicated in each cylinder group to protect against
- * catastrophic loss.  This is done at `newfs' time and the critical
- * super-block data does not change, so the copies need not be
- * referenced further unless disaster strikes.
- *
- * For filesystem fs, the offsets of the various blocks of interest
- * are given in the super block as:
- *      [fs->fs_sblkno]         Super-block
- *      [fs->fs_cblkno]         Cylinder group block
- *      [fs->fs_iblkno]         Inode blocks
- *      [fs->fs_dblkno]         Data blocks
- * The beginning of cylinder group cg in fs, is given by
- * the ``cgbase(fs, cg)'' macro.
- *
- * Depending on the architecture and the media, the superblock may
- * reside in any one of four places. For tiny media where every block
- * counts, it is placed at the very front of the partition. Historically,
- * UFS1 placed it 8K from the front to leave room for the disk label and
- * a small bootstrap. For UFS2 it got moved to 64K from the front to leave
- * room for the disk label and a bigger bootstrap, and for really piggy
- * systems we check at 256K from the front if the first three fail. In
- * all cases the size of the superblock will be SBLOCKSIZE. All values are
- * given in byte-offset form, so they do not imply a sector size. The
- * SBLOCKSEARCH specifies the order in which the locations should be searched.
