MPSAFE - mutex - better exclusive lock sequencer, bug fixes, abort
* Redo the exclusive lock chaining algorithm. Use an explicit
link structure and directly pass ownership to the next thread
waiting on an exclusive lock.
* Exclusive locks can be aborted via mtx_lock_ex_link() and
mtx_abort_ex_link().
* Lots of misc bug fixes.
