1.0.10.29: MUTEX refactoring & optimization
* (SETF MUTEX-VALUE) removed entirely. Using it was never sane,
and in the new setup entirely broken.
* On futex platforms, keep track of state of the mutex: free, taken,
or contested (taken and may have one ore more threads waiting).
* On release, if the mutex is not contested, there is no need to
perform the wakeup.
* Document assumptions made by GET-MUTEX & RELEASE-MUTEX better.
* Update FASL version.
