Remove group permission on the system manager socket so that restricted
clients cannot use it to get unrestricted access. It is assumed that the
session manager system service (wireplumber) is running as pipewire user
and will get access to the manager socket, while other clients are
members of the pipewire group and will only get access to the normal
socket.
Modern heterogenous multiprocessor systems rely increasingly on
scheduler hinting for efficiency gains and system optimisation.
This is especially true on embedded systems, where background
tasks such as audio daemons should be consigned to the most
power-efficient core in the system. Left to its own devices, the
Linux Completely Fair Scheduler tends to migrate Pipewire to
more performant cores, even when this is unnecessary.
Luckily, CFS can be told by a task to clamp its utilisation values.
Coupled with energy-aware scheduling, this allows the scheduler to
make better informed decisions about where tasks should be placed,
and what pstate to set for the CPU it is running on.
Enable the user to configure UCLAMP_MIN and UCLAMP_MAX values via
arguments to libpipewire-module-rt.

In JSON, the colon actually is used for assignment, but in spa_type_info
the colon is used as a separator. To properly parse and pass the
properties to the videotestsrc, the key has to be enclosed by quotation
marks to prevent splitting by the JSON parser.
Commit 9b29bcd4e8 ("conf: set description for test nodes") set the
description only for the minimal.conf and pipewire.conf and skipped the
pipewire-vulkan.conf.
Set the description for pipewire-vulkan.conf, too.
Add access.socket option, which sets PW_KEY_ACCESS based only on which
socket the client connected from.
Remove the executable-based permissions and all old options. Add
access.legacy=true option that enables the old default behavior. The
legacy mode cannot be used together with the socket-based access.
Emit warnings if any of the removed old options have been set.
Set pipewire.sec.flatpak=true for Flatpak applications.
The socket-based access ignores PW_KEY_CLIENT_ACCESS and the Flatpak
status when setting PW_KEY_ACCESS. Dealing with them becomes
responsibility of the session manager (or equivalent) which processes
the permission rules.
Make the default access.socket value compatible with the
module-protocol-native default two-socket configuration.
However, if neither access.socket or access.legacy is specified, we will
for now use the legacy mode for backward compatibility.
If no socket configuration specified for a server, create two sockets,
"CORENAME" and "CORENAME-manager" where CORENAME is the value computed
by get_server_name.
Add nofail flags to some filter-chain examples to avoid aborting on
startup and leaving the system in a silent state.
Add some more comments to guide people to change the paths to the
filters and config files where needed.
`wpctl status` shows the description of device nodes. Therefore, the
videotestsrc and audiotestsrc are listed as "(null)" if the example
configuration of the sources is used.
Set the description in the example for how to configure the audiotestsrc
and the videotestsrc.
JACK does not automatically generate aliases, so don't do that either.
The problem is that no new ports can be created if one already exists
with the same name or any of the aliases. This causes problems when a
port is renamed and a new port is created with the old name because the
alias might still be the old name and port creation fails.
Add a jack.fill-aliases for this purpose.
Fixes#3154
Add a condition to load the session manager and pipewire-pulse. This
makes it possible to disable the exec based on a context.properties
override.
Add a condition to load the access module. This makes it possible to
disable the default access behaviour and override with a custom one.
Fixes#3160
Make an option to allow link.passive properties and set it to false by
default.
This effectively ignores the link.passive properties from the session
manager, jack clients and pw-link when set. This is a good idea because
the logic for making passive links is better handled in the core.
These drop-ins are not meant to be enabled by default, so let's move
them to fontconfig style *.conf.avail/ subfolders from which they can
be copied or symlinked to a location that will get merged into the
corresponding configuration file.

But instead ship config override files to enable it again.
The idea is that distros can make extra packages that can than be
installed to enable the upmixing.
Also ship a config file to enable more samplerates.
Fixes#3081
Executables are installed in the bindir by default. And
furthermore if the directory is explicitly specified, then
the target won't be considered when setting up $PATH in the devenv.

Currently, among others, the `pipewire-pulse` executable is an
exact copy of the `pipewire` executable. Use meson's
`install_symlink()` to avoid the need for compiling the same thing
multiple times. Also use `custom_target()` so that the aliases
are available in an uninstalled environment.
Do the same for `pw-cat`. The benefit is that all aliases
of `pw-cat` are now available in an uninstalled environment.
This commit increasese the minimum meson version to 0.61.1
as that is needed for `install_symlink()`.
The reason for using 0.61.1 instead of 0.61.0 is the following bug:
https://github.com/mesonbuild/meson/issues/9820
Now that always-process nodes (the default for jack clients) can never
idle (even with passive nodes), force the qsynth client to
node.always-process = false
We can then also use the new node.passive = out handling to only idle
and suspend when nothing is linked on the input ports.
Make it possible to conditionally load modules, objects and exec by
adding match rules for context properties.
This makes it possible to only load a module when property is set,
which makes it possible to unset a property in a local config to disable
module loading. One example is the x11 modules, which can then be
disabled on a per user bases based on config overrides.
Add support for using other clocks.
clock.id can be used to set one of the system clocks.
clock.device can be used to open a clock device such as a PTP clock
device.
Use a dll to track the progress of non-monotonic clocks.
Make jack.merge-monitor true by default because this is what JACK also
does.
Add an exception for Mixxx because that makes it easier to select the
capture/monitor ports.
Fixes#1760
