6bbcab3ec4 Clean up MFS a bit:
- Remove unused includes.
 - Add include guards to headers.
 - Use unsigned variables in case they're never going to hold a negative
   value. This causes GCC's complaints to disappear and should make flexelint
   a lot happier, too.
 - Make functions private when they're used only within a module.
 - Remove unused variables.
 - Add casts where appropriate.

d5dee93bee Support for larger disks.
- MFS, df(1), fsck(1), badblocks(8), de(1x) now compute the
  superblock's s_firstdatazone value if the on-disk value is zero
- mkfs(1) sets s_firstdatazone in the superblock to zero if the
  on-disk field is too small to store the actual value
- more agressive mkfs(1) inode number heuristic, copied from r5261

a0d8cc0765 - No maximum block size any more.
- If allocation of a new buffer fails, use an already-allocated
   unused buffer if available (low memory conditions)
 - Allocate buffers dynamically, so memory isn't wasted on wrong-sized
   buffers.
 - No more _MAX_BLOCK_SIZE.

c078ec0331 Basic VM and other minor improvements.
Not complete, probably not fully debugged or optimized.
