509152108a sco-source: update clock position and duration at correct rate

rate. Update its position taking this into account.

f1d9b2317c sco-sink: adjust data flush timeout for msbc according to packet size 
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.

4144427655 ofono/hsphfpd: force write_mtu=24 for mSBC codec 
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.

8bc711ce4d bluez5: backend-ofono: Add mSBC support 
oFono tries to use the best codec when setting up the audio connection, so
the codec to use is known during call to `acquire` function, after the
transport has been created.
To get the codec before creating the transport, an audio connection is
set-up and discarded during `ofono_audio_card_found()`. It should return
the best codec available, which should not change during the time the
remote is connected.

mSBC can be enabled by passing "bluez5.msbc-support=true" parameter to
pipewire-media-session.
mSBC is automatically selected if remote device supports it.
