- Try to keep snapshot indirect blocks contiguous.  This speeds up snapshot
  creation by a factor of ~3 and reduces the file system suspension time by
  a factor of ~5.

- Refine the scope of WAPBL transactions and the limit for deallocations in
  one transaction so we should no longer get a "wapbl_flush: current
  transaction too big to flush" panic when creating or removing snapshots
  on larger logging disks.

- fss(4): Allow FSSIOCSET to set the initial flags.  Add a new flag
  "FSS_UNLINK_ON_CREATE" to unlink the backing store before the snapshot
  gets created.  With this change dump(8) no longer dumps the zero-sized,
  but named snapshot it is working on.
