Add options to change the 'prefix' and 'sysconfdir' values shown in
documentation, e.g. on config file man pages.

Update CI to set them, so that its produced output doesn't show
/builds/pipewire/... on man pages

Make a rtprio-server and rtprio-client option. Leave the server
priority by default to 88 but lower client priority to 83. JACK
does something similar by setting clients to rtprio-server - 5.

Make module-rt use the client priority by default and bump the server
priority explicitly in the config file.

Leave the pulse-server to the default rtprio-client, there is no reason
to lower this any further because it is really just a regular client.

Bump the ffado packetizer thread to rtprio-server + 5 because that is
also what JACK does.

88 is still much higher than the value of 60 that JACK uses in
Fedora but now this is at least configurable.

SNAP containers have two main "audio" security rules:

 * audio-playback: the applications inside the container can
   send audio samples into a sink

 * audio-record: the applications inside the container can
   get audio samples from a source

Also, old SNAP containers had the "pulseaudio" rule, which just
exposed the pulseaudio socket directly, without limits. This
is similar to the current Flatpak audio permissions.

In the pulseaudio days, a specific pulseaudio module was used
that checked the permissions given to the application and
allowed or forbade access to the pulseaudio operations.
With the change to pipewire, this functionality must be
implemented in pipewire-pulse to guarantee the sandbox
security.

This patch adds support for sandboxing permissions in the
pulseaudio module, and implements support for the SNAP audio
security model, thus forbiding a SNAP application to record
audio unless it has permissions to do so.

The current code for pipewire-pulseaudio checks the permissions
of the snap and adds three properties to each new client:

 * pipewire.snap.id: contains the Snap ID of the client.

 * pipewire.snap.audio.playback: its value is 'true' if the client
   has permission to play audio, or 'false' if not.

 * pipewire.snap.audio.record: its value is 'true' if the client
   has permission to record audio, or 'false' if not.

These properties must be processed by wireplumber to add or
remove access permissions to the corresponding nodes. That
code is available in a separate patch: https://gitlab.freedesktop.org/pipewire/wireplumber/-/merge_requests/567

Passing strings has been deprecated:

Use (fixed-up) Doxygen manpage output for all program & module manpages.

This also allows formatting the manual pages properly in the HTML docs.

The Markdown pages work properly only with Doxygen >= 1.9.7, older
versions put them to wrong place in the HTML docs.

Enable LE Audio support by default if liblc3 is present, the Pipewire
implementation should be OK. Remove unused HAVE_BLUETOOTH_BAP define,
we don't have any #ifdefs for this.

The feature is still disabled by default in BlueZ, which also now takes
care of necessary hardware feature checks, and should be safe to enable
on Pipewire side.

* Add support for running the sink as a driver
* Detect which compressed formats are actually supported
* Correctly open/close/start/stop device according to the node commands
* Shift away from tinycompress and use Compress-Offload ioctls directly
  to be able to access various caps information (including fragment sizes)
  which are unavailable in the tinycompress API
* Implement SPA_PARAM_PropInfo and SPA_PARAM_Props support

This commit implements generating /etc/security/limits.d/20-pw-defaults.conf and
/etc/security/limits.d/25-pw-rlimits.conf files. The numbering is arbitrary and
may very well warrant being in the reverse order, however `man 5 limits.conf`
does not appear to specify the parsing order or even say exactly how multiples
matches will resolve, so the value can be adjusted later, if required.

The actual limit values, the match rule and even whether each file is to be
installed can be changed via the build system before compilation. Likewise
the files can be modified or (re)moved during distro package building phase.

The 20-pw-defaults.conf should only be installed on legacy systems lacking both
a modern kernel and up to date systemd, because all it does is set the current
Linux default. Accordingly its not installed by default.

Many distributions provide outdated libcamera versions. This change should also help making changes to libcamera itself.

System libcamera is kept a default to avoid breaking existing build processes relying to packaged libcamera.

SOFA is a file format used for storing and accessing spatial audio data, namely head-related transfer functions. These can be used to create binaural spatial sound using head- or earphones.

This commit introduces libmysofa as an optional dependency for loading SOFA files and creates a spatializer plugin for the filter-chain

ci: install libmysofa-devel for full build

ci: bump FDO_DISTRIBUTION_TAG

* Decouple FFmpeg integration in pw-cat from the ffmpeg option; if
  one wants to use Compress-Offload but not the ffmpeg SPA plugin,
  it is then possible to just pass -Dpw-cat-ffmpeg=enabled to meson.
  Likewise, this also makes it possible to build the ffmpeg plugin
  without extending pw-cat.
* tinycompress does not need to be detected in the root meson.build,
  since it is only needed by the alsa plugin.

This makes paprefs work.

The volume plugin was an experiment that's not really used anywhere
that we're aware of. As such it makes sense to switch the default to
disabled state and skip building something no one probably needs.

The RTKit module is being replaced by the RT module. Currently, it is
always built if D-Bus is present. For packagers, it can be beneficial to
be able to disable the legacy module. Add a Meson option to allow for
exactly that. Make it enabled by default to not change default behavior.

Since XFixes version 6[1] it is possible to mark
