  Log:
  Add locking to the kqueue subsystem.  This also makes the kqueue subsystem
  a more complete subsystem, and removes the knowlege of how things are
  implemented from the drivers.  Include locking around filter ops, so a
  module like aio will know when not to be unloaded if there are outstanding
  knotes using it's filter ops.
  
  Currently, it uses the MTX_DUPOK even though it is not always safe to
  aquire duplicate locks.  Witness currently doesn't support the ability
  to discover if a dup lock is ok (in some cases).
