  Log:
  Fix the recent panics/LORs/hangs created by my kqueue commit by:
  
  - Introducing the possibility of using locks different than mutexes
  for the knlist locking. In order to do this, we add three arguments to
  knlist_init() to specify the functions to use to lock, unlock and
  check if the lock is owned. If these arguments are NULL, we assume
  mtx_lock, mtx_unlock and mtx_owned, respectively.
  
  - Using the vnode lock for the knlist locking, when doing kqueue operations
  on a vnode. This way, we don't have to lock the vnode while holding a
  mutex, in filt_vfsread.
