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.)

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

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.

e9d17d38b5 avoid unnecessary aging of buffers. This used to make sense, when buffer 
caches were much smaller, but makes little sense now, and will become more
useless as RAM (and buffer cache) sizes grow.  Suggested by Bob Baron.
