Use generic lock-free queue for async threads

Queues used for communication between async threads and scheduler threads
have been replaced with lock-free queues.

Drivers using the driver_async functionality are not automatically locked
to the system anymore, and can be unloaded as any dynamically linked in
driver.

Scheduling of ready async jobs is now also interleaved in between other
jobs. Previously all ready async jobs was performed at once.
