score: Move thread queue MP callout to context
Drop the multiprocessing (MP) dependent callout parameter from the
thread queue extract, dequeue, flush and unblock methods. Merge this
parameter with the lock context into new structure Thread_queue_Context.
This helps to gets rid of the conditionally compiled method call
helpers.
