 Log Message:
 Pull up following revision(s) (requested by hannken in ticket #169):
        sys/ufs/ffs/ffs_snapshot.c: revision 1.87
 ffs_copyonwrite():   Only use si_snapblklist if it is already allocated.
 ffs_snapshot_read(): Use IO_ALTSEMANTICS to allow reading a snapshot vnode
                      beyond file system size.  Needed to read the snapblklist
                      on mount.
 Persistent snapshots work again.
 Should fix PR kern/37425: fss_snapshot_mount panic during fsck.
