Pull up following revision(s) (requested by riastradh in ticket #725):

        etc/rc.d/mountall: revision 1.12
        external/cddl/osnet/dist/uts/common/fs/zfs/zfs_vnops.c: revision 1.59
        external/cddl/osnet/sys/kern/misc.c: revision 1.8
        external/cddl/osnet/dist/uts/common/fs/zfs/spa_history.c: revision 1.5
        external/cddl/osnet/dist/uts/common/fs/zfs/spa_history.c: revision 1.6
        external/cddl/osnet/dist/uts/common/fs/zfs/zfs_vnops.c: revision 1.60
        external/cddl/osnet/dist/uts/common/fs/zfs/zfs_vnops.c: revision 1.61

Define VOP_STRATEGY on zfs device nodes too.
Fixes eternal hangs in attempts to do I/O on device nodes on zfs.
XXX pullup

Teach zfs spec nodes to VOP_BWRITE too.
Fixes hang on writing to, e.g., ffs mounted on a device node that
lives on zfs.
XXX pullup

Teach device nodes on zfs to handle fsync by calling spec_fsync too.
If zfs=YES, unconditioally do zfs mount/unmount -a.

If you set zfs=YES, presumably you positively want the automatic rc.d
actions, so if there's no /sbin/zfs or if zfs can't find pools with
/etc/zfs/zpool.cache, presumably you would like feedback about that
in rc.log.

Report the OS name and release appropriately for NetBSD.
We are not OpenSolaris or uts!

Mark previous #ifdef __NetBSD__, per request from hannken.
