pipewire: update 0.3.67 -> 0.3.68

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

This release contains a huge number of changes, some of which might cause
regressions. Please report anything that seems to fail after the upgrade.
UCM devices in particular might have changed names, profiles and ports that
might require changes in custom scripts.

  - Symbolic links to the pipewire binary are now used instead of recompiling
    the same binary multiple times.
  - Changes to the graph scheduler related to quantum/rate updates and
    calculation of the node states. Things should start and switch between
    quantums and rates more smoothly now and especially virtual devices should
    now only run when required.
  - A new RTP session module was added. This uses the Apple MIDI protocol
    to configure low-latency bidirectional MIDI (and with a PipeWire specific
    extension, also audio) between machines. OPUS encoding was added to the
    RTP formats. The SAP module was separated from the rtp-sink/source module
    to make it more usable.
  - A new runtime debug property was added to all streams and nodes to trigger
    a save of the raw samples to a wav file. Support for this has also been
    added to the echo-canceler to debug potential issues.
  - Module pulse-tunnel has improved rate matching and synchronization
    support. It should also not drift anymore for capture devices.
  - The link-factory now ignores by default the link.passive property. This means
    that tools like pw-link or jack clients and wireplumber can't make passive
    links anymore. The reason is that there is now much more advanced logic in
    PipeWire itself to handle passive links based on node and port properties.
  - The RAOP sink was ported to new OpenSSL functions. Digest passwords are
    handled correctly now and support for more devices was added.
  - The ACP code was updated with new PulseAudio UCM code: "Create multiple
    profiles per verb for conflicting devices". This might change the names
    of devices, profiles and ports so scripts might need to be updated.
  - Upmixing is disabled again by default. We now ship config files that
    distros can install to enable upmixing again. The reason being that PipeWire
    should not apply fancy DSP processing to audio by default.
  - Many cleanups and bugfixes, including some crashes and memory corruption
    bugs.

  - Various FreeBSD compilation fixes.
  - Don't crash when calling _connect twice in stream/filter. (#3091)
  - Links are now installed instead of compiling the pipewire binary
    multiple times.
  - There is now a new core event bound_props that augments the bound_id event
    with the global properties. This can be used to get the global.serial among
    other global properties. It also makes it possible in the future to let the
    server allocate unique names or uuids.
  - Fix a bug where the server could go into an infinite reconfigure loop when
    the samplerate of a driver would change.
  - When a samplerate was forced, restore the previous best samplerate when the
    samplerate is no longer forced. (#2133)
  - Rework how the states of the nodes in the graph are calculated. A more
    refined algorithm is now used that only runs nodes that need to run.
  - Rework how the quantum change is applied to the graph. Drivers are now
    responsible for using the new updated rate/quantum before starting a new
    cycle. This avoids starting a cycle with an old quantum first.
  - pw-stream and pw-filter will now ensure that the Trigger event is called
    from the main thread.
  - node.force-rate=0 will now force the node.rate on the graph, forcefully
    switching the hardware into the new rate if possible. (#3026)
  - Additional checks were added to the thread-loop to check locking order.
  - Additional checks were added to pw-stream and pw-filter to check if methods
    are called from the right thread context.

  - A new RTP session module was added. This uses the Apple MIDI protocol
    to configure bidirectional MIDI (or audio) between machines.
  - SAP support was removed from module-rtp-source and module-rtp-sink and
    moved to a separate module. This makes it possible to use the RTP modules
    without SAP support as well.
  - The echo-cancel module now has support to save the signals to a wav
    file for debugging purposes.
  - The RTP modules now have support for the OPUS codec.
  - The RAOP module was ported to new openssl encryption functions and handles
    digest passwords correctly now.
  - module-raop-discover now has match rules to be able to select the streams
    and set properties.
  - Module pulse-tunnel has improved rate matching and synchronization
    support. (#3093)
  - Fix potential memory corruption and infinite loops because
    module-pulse-tunnel was unloaded from the wrong thread.
  - The link-factory now ignores by default the link.passive property. This means
    that tools like pw-link or jack clients and wireplumber can't make passive
    links anymore. The reason is that there is now much more advanced logic in
    PipeWire itself to handle passive links based on node and port properties.
  - module-echo-cancel will now clear its buffers after a suspend to avoid
    playing stray samples.
  - module-raop-sink will now handle 0 timing_port replies. (#3133)

  - The adapter module now has support for saving the raw audio to a wav
    file for debugging purposes.
  - The ACP code was updated with new PulseAudio UCM code: "Create multiple
    profiles per verb for conflicting devices". This might change the names
    of devices, profiles and ports so scripts might need to be updated.
  - Upmixing was disabled again by default. We now ship config files that
    distros can install to enable upmixing again. (#3081)
  - audioadapter and audioconvert have seen improvements in the experimental
    non-DSP/passthrough mode.
  - Fix a potential race where the dummy drivers could fail to stop a timer
    and cause endless warnings in the logs.
  - The ALSA plugin has experimental support for IRQ based scheduling. This
    should decrease latency for some (mostly USB) drivers. This should bring
    latency within JACK latency. More work on this will be done before the
    1.0 release later this year.
  - Audioconvert now has support for volume ramping. (#3046)
  - A new loop method was added the check if a thread is currently running the
    loop.
  - channelmix.disable and resample.disable now generate an error when true
    and channelmixing or resampling is required in the converter.

  - Fix a crash in some cases when a device was disconnected.
  - Support async transport state changes. This avoids some lockups when the
    bluetooth backend is having issues. (#3023)
  - Align BAP sinks. This improves synchronization between earpieces.

  - Improve properties in pw-top and pavucontrol.

  - Improve error handling from pulse-tunnel.
  - Generate silence correctly for unsigned formats as well.
  - Review buffer params. The streams should now just work with 1 or 2
    buffers.
  - module-rtp-send and module-rtp-recv now have support for the OPUS codec.

  - Make sure we don't call any callbacks anymore when deactivating. (#2781)

  - Sort the device by priority in deviceprovider. (#3072)
