The waiting requests of one camera should not be able to influence
queuing to another camera. Currently a request that is in the
waitingQueue and waiting for preparation blocks all requests of other
cameras even if they are already prepared. To fix that replace the
single waitingRequests_ queue with one queue per camera.
