jtk 6ddae4d140 Implement proper `..' locking in lookup code to avoid many potential
deadlocks.

copy up properly when adding a link to lower-layer only file.
(I believe there are still more deadlocks remaining.)

jtk c9c8daaf7c Add locking code to avoid deadlocks on vnode reclaim, which means the
addition of null_lookup, null_lock, null_unlock, null_islocked.

mycroft fce3e0874f Fix vop_link, vop_symlink, and vop_remove semantics in several ways:
* Change the argument names to vop_link so they actually make sense.
* Implement vop_link and vop_symlink for all file systems, so they do proper
  cleanup.
* Require the file system to decide whether or not linking and unlinking of
  directories is allowed, and disable it for all current file systems.
