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.
