Paolo Bonzini a7b91d35ba coroutine-lock: make CoRwlock thread-safe and fair 
This adds a CoMutex around the existing CoQueue.  Because the write-side
can just take CoMutex, the old "writer" field is not necessary anymore.
Instead of removing it altogether, count the number of pending writers
during a read-side critical section and forbid further readers from
entering.
