Implement a completely new getwork scheduler. 

Stage all work from the one thread, making it possible to serialise all requests minimising the number of getworks requested or local work generated.
Use a pthread conditional to wake up the thread whenever work is removed to generate enough work to stay above the watermark set by opt_queue.
Remove all remnants of the old queueing mechanism, deleting the now defunct queued count.
