Return -EIO when we can't enumerate the params
Don't check for end-of-params in a2dp-sink, we do that in the codec.

Remove >2 channel support until upstream
Fix availability groups

Wait with inotify until we can access the device node before emiting
the new device.
Clean up alsa-udev and make it more like v4l2-udev

Wait until the device is accessible before exposing it.

See #461

for planar formats, we should not remap twice or we undo the
remapping.

See #461

Fixes first \n

Descend into the type info of the array. Fixes names of channels
in position array.

The codepath `pa_alsa_ucm_add_ports` -> `probe_volumes` ->
`pa_alsa_path_probe` was never called leading to no HW volume being set
up when loading a card through UCM. PulseAudio calls this from
`card_set_profile` -> `pa_alsa_{sink,source}_new`.

data->path (current path for selected profile) is not set yet here
resulting in segfaults. We are not interested in printing that anyway
but instead care about the iterated `path` from data->paths.

Only remap channels on the planar buffers.

See #472

Use the json escape function to escape keys and strings.
Make most put functions accept an optional key
Use flags helper for permissions as well

Dumps the complete object tree as json so that it can be processed
with tools like jq

pulseaudio -> pipewire
PULSE_* -> ACP_*

Hopefully this does not interfere with pulseaudio anymore.

See #436

Use the configured fd in the source for reading and writing because
the transport might be disconnected and cleared from the main thread
at any time.

Config files read from this variable - currently only media-session.d -
do not get copied to the build directory but are only ever copied during
install. In order to have media-session.d/with-pulseaudio detected when
`make run`'ing from the build directory PIPEWIRE_CONFIG_DIR must point
to the source directory containing these files.

The root of the build directory does not contain modules, these reside
in src/modules/.

The null sink pulls in data and provides data after it got the
data in _process.

See #472 #442

We then remap the tmp array to the destination array.

Fixes #477

ldac frames are larger and need more space.

See #449

Fixes #399

For batch devices that are not usb devices, lower the period and
add an extra period of heardoom to avoid xruns.

See !330

Make the format_info const in codec_init, we just need to read the
final negotiated format in some cases.
Add some more ldac bit depths we support.

Don't read too large chunks from the ringbuffer but in minreq
increments. This is more what pulseaudio does.

Fixes #463
