After the dead process is detected, pthread_mutex_consistent() will
be called. After that, the pthread_mutex_unlock() should also be
called to unlock it: "It is the responsibility of the application to
recover the state so it can be reused."

If the code is crashed and the mutex may be in bad status. The user
has to mannually remove it. The fix will remove the shared mutex
if no process is using it.

Previously, when a process holding a shared mutex was killed,
the next time an RSMI application was started, it would not be
able to obtain the mutex--the application would have to exit.
This fix uses pthread_mutexattr_setrobust() to detect this
situation and act accordingingly.
Also, add some missing, needed mutexes and move mutexes
closer to where the protect resource is used.
