kernel - Record token & mplock collisions in thread->td_wmesg

* Record token & mplock collisions which the lwkt thread schedule spins
  on in the thread wmesg, which will show up in ps, top, etc.

  This makes it a lot more obvious when a thread is stalling on a token
  or the mplock and is generally superior to the old per-cpu collision
  record.
