Use a different way to generate the upper bits of the ASYNC mask
instead of undefined shift as warned by sanitizer
Add some unit test for this
See #497
Instead of using a hardcoded value for the minimum delay between writes,
select it according to the mtu/packet size that is currently used.
This is necessary for correct playback with lower mtu values.
Kernel should provide the correct mtu/packet size to use for SCO socket
I/O, but it does not currently appear to (as of linux 5.9), see
https://lore.kernel.org/linux-bluetooth/20201210003528.3pmaxvubiwegxmhl@pali/T/
When using mSBC, instead of using the (incorrect) kernel-provided value,
hardcode mtu to 24, corresponding to ALT1 mode. BT-UART adapters should
not require specific mtu, and it appears most BT-USB adapters only
support ALT1, see
https://lore.kernel.org/linux-bluetooth/20201210012003.133000-1-tpiepho@gmail.com/
This code needs to be revised when the issue is sorted out on the kernel
side.
Add setting bluez5.msbc-force-mtu for easier debugging in special cases.
Leave read_mtu as the detected value --- it does not seem to affect
whether BT-USB can record, but Raspberry Pi BT-UART fails to record if a
different value is used.
Make a new complete event and use it instead of the start event
Use the start event at the start of the cycle
Make the profiler also log incomplete graph cycles
When a stream is marked don't reconnect, clear the target-node so that
it does not accidentally gets linked to a save target. This makes it
kill the monitor stream from pavucontrol after a client disconnects.
Currently alsa_read and alsa_write assumes that all the frames committed
using snd_pcm_mmap_commit are read or written, which is probably true.
However, as it could be some corner cases add a warning to notice this
fact.

Remove the separate error event and merge with the done event with
error code. This then also marks the sample as done when in error
so that it gets cleaned up properly.
Fixes#486
We can't write more to the ringbuffer than its maxsize. Some clients
send more than the negotiated maxsize and cause a crash if we don't
clamp.
See #440
