Subject: [PATCH BlueZ v3 0/4] test-runner: Add support for audio daemons

Those patches add DBus session and an audio card so it should be possible
to start an audio daemon like PipeWire in the VM.

Frédéric Danis (4):
test-runner: Add DBus session support
doc/test-runner: Add audio config options
test-runner: Add audio card support
test-runner: Add udevd and trigger events

Since v2:
- move doc/test-runner changes to its own patch
- replace AUDIO_SUPPORT by TESTAUDIO to be consistent with the other
parameters
Since v1:
- Fix checkpatch errors
