Simply and rationalise pthread_mutex implementation, in preparation
for implementation of condition variables.

* Use the native pthread_mutex_t directly; we no longer have our own
  VgMutex type nor a fixed array of them.

* Give ThreadState a new field q_next :: ThreadId, used to make a
  linked list of threads waiting on a mutex, or condition variable.
