PipeWire 0.3.21

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

- Highlights
  - Many PulseAudio compatibility fixes. Handling of corked
    streams, the prebuf setting, seek modes and stream flags
    are now implemented correctly.
  - Ports and Profiles are now managed by the session manager
    and can save and restore previous settings.
  - ALSA device handling has been tweaked for maximum
    compatibility at the expense of latency. There are tuning
    options in the config file.
  - Improved Bluetooth support. HSP is disabled by default
    because it is old and deprecated and in some cases causes
    conflicts with the newer HFP profile. Codec switching is
    now implemented as well.
  - PipeWire accepts donations with liberapay now.

- PipeWire improvements
  - Improve draining in pw-stream.
  - pw-stream now uses busy metadata by default. This makes sure
    that no writer can write to buffers when readers are still
    busy.
  - Fix handling of empty array/choice instead of failing.
  - Fix crashes when creating properties from empty strings.
  - Make it possible to pass an array to module-access
    access.allowed variables
  - Fix small bug in argument parsing in pw-cat

- Session-manager
  - Restore route volumes in all cases, also when switching
    routes.
  - Use a default route volume for unknown routes instead of
    letting the system decide on a default.
  - Improve profile handling. Don't try to restore unavailable
    profiles. Implement the profile switching in the session
    manager now.
  - Fix handling of Virtual sources as defaults.
  - Handle port switching in the session manager. Implement
    save and restore of default ports per profile.

- GStreamer
  - Fix a crash with zero SPA_PARAM_BUFFERS_size

- Device support
  - v4l2-source will now respect the requested memory types.
  - ALSA buffering has been tweaked. USB devices should have
    less XRuns by default. Parameters can be tweaked to
    decrease the latency on capable devices. Also fix a case
    where a quantum change would cause an xrun.
  - Fix mute in bluetooth devices
  - bluetooth devices are not paused in idle anymore for
    improved compatibility.
  - Codec switching for bluetooth is implemented along with
    config options to select the codecs manually.
  - HSP for bluetooth is now disabled by default. Most devices
    support the newer HFP profile and some devices fail when
    both are available.
  - Reduce the amount of events the ALSA plugins emit by bundling
    them.

- PulseAudio server
  - Implement the suspend command
  - Fixes volume in sample info
  - Fix playback of samples, sometimes samples would be clipped
    short. Also implement the target sink for the sample.
  - Use rate match to feed samples. This way the latency can
    be kept to a minimum.
  - Latency has been tuned some more, more closely emulating
    pulseaudio behaviour.
  - Improve default sink/source handling. Make sure all events
    are sent correctly when defaults change.
  - Handle underrun better without causing sync issues. Make sure
    to pause in corked state.
  - Implement rewind due to seeks, fixes GStreamer seeking.
