* Add timeouts on recving packets
Add a timeout when recving packets from the worker thread in case it hangs.
Add an exit condition just in case the while loop goes on forever.
* Add a timeout to recorder thread join.
* Wait for recorder thread to be invoked in tests
Remove the while loop and instead wait for segments to be produced by the background worker thread.
* Allow worker to resume before stopping to fix timeouts
* Lower test timeout further
* Remove test_stream_ended since it is flaky
This test doesn't really add additional value on top of other tests.
* Remove dependencies on keepalive from StremaOutput and stream_worker
Pull logic from StreamOutput and stream_worker into the Stream
class, unifying keepalive and idle timeout logic. This prepares
for future changes to preserve hls state across stream url changes.
