BlueZ may connect transports long after DEVICE_PROFILE_TRANSPORT_SEC has
passed on already existing devices. When this occurs, the bluez5
pipewire device should notify that the profile enumeration has changed.
Ignore these events during A2DP codec switch, and handle any changes
when the switch completes.
Set form factor, name routes based on form factor.
Improve profile names
Make card and node names like pulseaudio, with bt address in them.
Fill in port type in the route info.
Fixes#544
Implement routes on the device. This makes it possible for the
session manager to restore the device volumes.
Use validate_config to get the negotiated channels for the route
volumes.
SCO socket connect may fail with ECONNABORTED if it is done too soon
after previous close. To avoid this in cases where nodes are toggled
between stopped/started rapidly, postpone release until the transport
has remained unused for a time. Since this behavior appears common to
multiple SCO backends, do it for all SCO backends.
Move SCO polling to a single place, and abstract mtu handling.
Autodetect suitable tx packet size based on rx, instead of relying on
the kernel providing correct values.
Backends don't necessarily allow for opening the same device multiple
times, and it shouldn't be necessary.
Since source and sink are not necessarily both running at the same time,
refcount the transport acquire/release so that it knows to close the fd
only when no source/sink is running.
Let the transport manage the fd lifecycle, also closing it once it is
not needed.
Don't return the fd from acquire(), since each transport is associated
with a single socket fd.
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.

mSBC is automatically selected if remote device supports it.
Make the list of supported codecs available.
Register all supported codecs endpoints
Find the codec from the endpoint name
Put the codec on the transport for the sink to find.
As hsphfpd is a prototype and its API subject to change, this backend is
disable by default.
This skeleton connects to hsphfpd daemon and list the managed devices.
Actually compile the codec config and declare the config as extern
or else it's just all 0.
Only acquire the transport when ACTIVE.
Implement transport state_change signal and acquire the transport
when going to pending/active.
Try to acquire the transport before we expose the device if we
can.
Force device expose when we get the device ServicesResolved=1 property
update.
Free transport when the rfcomm is closed.
Implement various DBus signals to detect dynamic property updates.
Use hooks for the implementation of the transport
Add events to the transport
Handle the destroy event of the transport to release the reference
in source and sink.
