8c21bc6224 Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD. 
- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
    may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
    Snapshots may not be opened for writing and the attributes are read-only.
    Use the mtime as the time this snapshot was taken.
    Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
  one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
  a vnode.
- Add snapshot support to ls, fsck_ffs and dump.

Welcome to 2.0F.

2dc6ea479c Don't use an ffsv1 superblock from 64k (SBLOCK_UFS2) when looking 
for the main filesystem superblock.
64k is the offset of the first alternate if the blocksize if 64k.

fe36fefa1a Oops. The clearinode macro had the UFS2 case reversed, causing it to 
zero out two inodes in the plain FFS case, since UFS2 dinodes are
twice as big.

750ed85d47 Write update some old fields when writing the superblock, similar to 
ffs_oldfscompat_write() in the kernel. Use the old totals when
time < old_time (i.e. an old kernel or fsck wrote the filesystem last).
When setting the date back on a new kernel, that works out ok, since
new kernels always update both fields.

42614ed3f3 Add support for UFS2. UFS2 is an enhanced FFS, adding support for 
64 bit block pointers, extended attribute storage, and a few
other things.

This commit does not yet include the code to manipulate the extended
storage (for e.g. ACLs), this will be done later.

FreeBSD.
