[FFS] Remove the FFS/UFS driver

The upstream driver is not maintained and the file system itself
is in a semi-abandoned state.
Originally imported at 3a3ef631d1

The driver is written by Lee Jae-Hong, updated by Bo Brantén.
ReactOS porting made by Peter Hater and Pierre Schweitzer.
Follow updates at http://www.acc.umu.se/~bosse/

FS Recognizer code is left to keep the FS support as an
installable driver.

* A directory consists of some number of blocks of DIRBLKSIZ

*
* Each DIRBLKSIZ byte block contains some number of directory entry
* structures, which are of variable length. Each directory entry has
* a struct direct at the front of it, containing its inode number,
* the length of the entry, and the length of the name contained in
* the entry. These are followed by the name padded to a 4 byte boundary.
* All names are guaranteed null terminated.
* The maximum length of a name in a directory is MAXNAMLEN.
*
* The macro DIRSIZ(fmt, dp) gives the amount of space required to represent
* a directory entry. Free space in a directory is represented by
* entries which have dp->d_reclen > DIRSIZ(fmt, dp). All DIRBLKSIZ bytes
* in a directory block are claimed by the directory entries. This
* usually results in the last entry in a directory having a large
* dp->d_reclen. When entries are deleted from a directory, the
* space is returned to the previous entry in the same directory
* block by increasing its dp->d_reclen. If the first entry of
* a directory block is free, then its dp->d_ino is set to 0.
* Entries other than the first in a directory do not normally have

/*
* Each disk drive contains some number of file systems.
* A file system consists of a number of cylinder groups.
* Each cylinder group has inodes and data.
*
* A file system 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 file system 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.
*
* Unfortunately the UFS2/FFSv2 change was done without adequate consideration
* of backward compatibility. In particular 'newfs' for a FFSv2 partition
* must overwrite any old FFSv1 superblock at 8k, and preferrably as many
* of the alternates as it can find - otherwise attempting to mount on a
* system that only supports FFSv1 is likely to succeed!.
* For a small FFSv1 filesystem, an old FFSv2 superblock can be left on
* the disk, and a system that tries to find an FFSv2 filesystem in preference
* to and FFSv1 one (as NetBSD does) can mount the old FFSv2 filesystem.
* As a added bonus, the 'first alternate' superblock of a FFSv1 filesystem
* with 64k blocks is at 64k - just where the code looks first when playing
* 'hunt the superblock'.
*
* The ffsv2 superblock layout (which might contain an ffsv1 filesystem)
* can be detected by checking for sb->fs_old_flags & FS_FLAGS_UPDATED.
* This is the default suberblock type for NetBSD since ffsv2 support was added.

* necessary. The file system format retains only a single pointer
