PipeWire 0.3.10

This is a bugfix release that is API and ABI compatible
with previous 0.3.x releases.

- Many improvements to the pulse layer.
  * GStreamer pulsesink element now works.
  * Fixes some segfaults.
  * Enable rtkit for client threads.
  * fixes capture of monitor stream by name
  * implement some more extensions, this makes paman
    work and removes some warnings.

- Many improvements to the GStreamer elements
  * negotiation rework, avoid calling GStreamer methods from
    the PipeWire callbacks because they might block and cause
    deadlocks.
  * Add support for non-string property values.
  * improve stability after buffer and format
    renegotiation.
  * Rework the device provider.
  * pipewiresink can now provide a stream that can
    be consumed by apps like cheese.

- Many improvements to the JACK layer:
  * Rework the buffer_size callbacks. Make sure we call
    the callback from a 'safe' thread and that we don't
    call the process callback while the application is
    handling the callback. This improves stability in
    apps like Carla when PipeWire dynamically changes
    the buffer size.
  * Improve compatibility with apps that call
    get_buffer_frames() with a 0 size (calfjackrack)
  * JACK can now create nodes that can be set as a
    sink/source in PulseAudio/ALSA apps (you can make an
    effects rack and set that as default sink for
    apps).

- Added a group id property for nodes. This makes it
  possible to schedule nodes with the same driver even
  when they are otherwise not linked together. To make
  this work well a new flag needed to be added to nodes
  to signal when they are ready for processing.

  Together with the GStreamer fixes, this makes things
  like:

   gst-launch-1.0 -v pipewiresrc path=51 stream-properties="props,node.group=1" !
         audio/x-raw ! pipewiresink stream-properties="props,node.group=1"

  work as expected with PipeWire managing the resampling
  to keep the clocks of the devices in sync.

  This can later also be used to force devices to be grouped
  together to create a JACK-like scheduling group.

- Streams and filter now use PIPEWIRE_NODE and
  PIPEWIRE_LATENCY env variables as fallback.

- ACP add per device port list. This makes UCM devices
  expose the right ports.

- Fix some segfaults in ACP and UCM.

- make pw-cat use the metadata to find default devices.

- The media session can now save and load audio device
  Profiles and Routes (volumes), stream volumes and
  the default sink and sources.
