Add necessary apis to bluez transport.
Add A2DP(AVRCP) absolute volume support. Source volume can only update to adapter node but not from due to AG nodes don't have route.
Since A2DP/HSP/HFP volume is already percentage itself, it has been mapped to pulseaudio volume then converting to linear volume.
There won't be further battery level updates when RFCOMM connection is
down, so remove the battery then.
Fix minor things with canceling the provider registration.
Auto-connect all paired & trusted devices on startup.
Since devices that already connected or powering off would reject the connecting requests, it should be fine with this behavior.
Also reconnect remaining profiles if only partial profiles are connected.
Implement switching HFP codecs in bluez5-devices, currently only for
backend-native.
Codecs are exposed via profiles similarly as for A2DP.
Some hardware appears to not properly reply to the +BCS message. Catch
these cases with a timeout, in which case we fall back to previously
existing transports.
SCO transports have timer-delayed release, but they need to be released
immediately when changing profiles to close connections before switching
to A2DP.
This does not work as intended, because we no longer do a codec switch
on device connect. It should be done in a different way, but since it's
not used for anything right now, can as well remove it.
This will prevent to run the different backends concurrently.
The native backend will only register to BlueZ if neither oFono nor
hsphfpd are running. If one of them starts, the native backend will be
unregistered and the corresponding backend will register to its daemon.
Make queueing a codec switch work properly. When receiving the dbus
reply, it should move to latest one. Others should be discarded.
Previously, it instead hit an assert, if there were more than two
queued.
Not all devices report their A2DP delay. In those cases, use a fallback
value of 150ms by default.
Make the delay adjustable with a SPA_Prop, and expose it as a part of
the route. Implement the corresponding parts in media-session.
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.

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.
