aaudio examples: handle disconnect in write_sine_callback
Automatically reopen the stream if we get disconnected.
Add a futex based signaling class so that the error callback can
immediately inform a waiting thread.
This can be used to prevent the system from playing an unpleasant sound
after the stream is disconnected.

We now use the -s option for seconds.

aaudio: fix getXRunCount
Mixer was not advancing FIFO when underflowed so the client could not
detect the xrun.
Also underruns could cause the stream to drift in time relative to other
streams.

Test: trigger underruns by sleeping in a callback

aaudio: add tests for device switch detection and refactor
Add detection for device switch during capture and playback tests:
write_sine, write_sine_callback, input_monitor, input_monitor_callback
Refactor tests and move simple player, simple recorder and utility
methods in separate header files and folder.
