. add all sys/sys headers not already present to help compiling
. take netbsd dirent.h and struct dirent; main result is
introducing d_type and d_namlen that have to be set by getdents()
in all FS code implementing it
. d_off is gone
. alignment of the struct has become 8 bytes instead of 4
. remove _MAX_BLOCK_SIZE, _MIN_BLOCK_SIZE, _STATIC_BLOCK_SIZE
. libminlib: cleanup unused yet duplicate code
. mfs: throw out the long-broken v1, v2 support
. new test for dirent contents filled by getdents()
Change-Id: I1459755c7ba5e5d1c9396d3a587ce6e63ddc283e
. also implement now-possible fsck -p option
. allows unconditional fsck -p invocation at startup,
only checking each filesystem if not marked clean
. mounting unclean is allowed but is forced readonly
. updating the superblock while mounted is now not
allowed by mfs - must be done (e.g. by fsck.mfs)
on an unmounted fs
. clean flag is unset by mfs on mounting, and set by
mfs on clean unmounting (if clean flag was set at
mount time)

- 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.
- 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
- 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.
