    Fix various issues in zfs life cycle, locking, and vop protocol.

    - Restore some zfs locking and unlocking that got lost randomly.

    - Enable use of the BSD vnode lock.  Lock order: all BSD vnode locks
    are taken before all zfs internal locks.  There remains an issue with
    O_EXCL, to be solved later (famous last words).  KASSERT the locking
    scheme up the wazoo.

    - Take our cruft out of zfs_lookup and move it to zfs_netbsd_lookup.
    Restore much of the way zfs_lookup looked to make merging future
    versions easier.  Disable use of the namecache for now because its
    locking dance is too scary to contemplate.

    - Implement BSD semantics for rename, to appease our tests.  This is
    a provisional kludge; eventually we need VOP_RENAME to take a flag
    specifying whether to use BSD semantics or POSIX semantics.

    - Simplify zfs_netbsd_reclaim and make it work.  Now that getnewvnode
    never tries to vclean anything itself, we need not worry about
    recursion of ZFS_OBJ_MUTEX locks.

    - Clarify and fix genfs node initialization and destruction.

    zfs passes most of our atf vfs tests now, including the rename races.

    Still to do:

    - fix the impedance mismatch between our permissions model and zfs's;
    - fix O_EXCL (nontrivial);
    - throw dirconc at it and see how badly it explodes;
    - find why zpool sometimes wedges itself during mkfs; and
    - find why pool caches sometimes seem to get corrupted.
