Log Message:
Pull up revision 1.18 (requested by hannken in ticket #334):
ffs/ffs_alloc.c:
- Add a missing ACTIVECG_CLR().
ffs/ffs_snapshot.c:
- Use async/delayed writes for snapshot creation and sync/uncache these buffers
  on end. Reduces the time the file system must be suspended.
- Remove um_snaplistsize. Was a duplicate of um_snapblklist[0].
- Byte swap the list of preallocated blocks on read/write instead of access.
- Always keep this list on ip->i_snapblklist so it may be rolled back when the
  newest snapshot gets removed. Fixes a rare snapshot corruption when using
  more than one snapshot on a file system.
ufs/ufsmount.h:
  - Make TAILQ_LAST() possible on member um_snapshots.
  - Remove um_snaplistsize. Was a duplicate of um_snapblklist[0].
