stream: schedule process from main thread when asked

Browse source 
Use 2 lockfree queues so that we can queue and dequeue from different
threads.
Call the process function from the main thread when requested
Rework the data push and pull logic to go through the queues
Update the examples for this new feature, video-play does not need
to schedule the process in the main thread anymore and block for it
to complete, this avoid a deadlock between the data and mainloop when
shutting down.
