PipeWire 0.3.20

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

- Highlights
  - Latency was reduced in ALSA and PulseAudio and time
    reporting has improved a lot.
  - Bluetooth now has a native HFP backed, SBC XQ and
    mSBC support.
  - Many bugfixes and improvements, improved device

- PipeWire improvements
  - pw-dump can now dump all objects such as Endpoints
  - pw-dump has a -m option to monitor changes
  - pw-dump can now dump metadata
  - pw-stream can now use the rate-match io to exactly
    produce the required number of samples for the
    current cycle. When using this feature, a stream can
    achieve the same low-latency as pw-filter.
  - spa-acp-tool can now load a custom profile-set and
    correctly parses the volume updates
  - There is now a nofail option when loading modules
  - The connection has been made reentrant to fix some
    strange random problems with metadata.
  - Turn some errors into warnings or simply info.
  - Executables are now built with PIE
  - S24OE formats should work now (MAudio FastTrack Pro)
  - Remove mlock warnings. Add support for mlockall with
    a config option.

- Session-manager
  - There are now config files for bluez and v4l2 modules
  - Improve ALSA device and node properties
  - Bluetooth devices have better properties now.
  - The default device routing has been improved.

- Device support
  - Port priorities are updated for UCM devices
  - ACP devices notify change in routes in all cases
  - There is now RW support in ALSA devices to increase
  - Many improvements to Bluetooth. SBC XQ support can now
    be enabled with a config option. mSBC can be enabled
    with an option.
  - Bluetooth devices not expose Routes so that they look
    more like how PulseAudio handles them
  - Gracefully handle missing profile-sets
  - There is now a native HFP backend
  - Improve card names in some cases.
  - pause-on-idle is now disabled for ALSA devices. This can
    reduce pops and clicks when the device is stopped.

- ALSA plugin
  - Use rate-match to reduce the latency
  - Implement a _delay() function to get smoother timestamps.
  - Fix property parsing. Fixes volume changes in alsamixer.

- PulseAudio server
  - Use rate-match to reduce the latency. This also reduces
    the buffering in audioconvert and improves timestamp
  - Implement rate changes now that we have rate-match
  - pactl stats will now work
  - Fix excessive memory usage when a capture client doesn't
    read fast enough.
