This allows closures to be properly unrefed when they are no longer
used instead of staying alive until wireplumber exits

Because GClosure has no weak references, we are now sharing the
GPtrArray that holds these references among all the active closures
and each closure is responsible for removing itself from the array
when it is finalized. The lua engine holds a reference to a "store"
object that also has a pointer to the array and when this "store"
is finalized, all closures are invalidated and removed. Even if they
stay alive afterwards, they are only holding a ref to an empty array

This script takes links that are created by policy-endpoint-client
and activates only the ones that should be active based on role
priorities

Useful to tag objects with their creation time

As with endpoint streams, there is not much use for endpoint links
in this updated design. This will be re-evaluated.

Instead of adding Props on endpoints again and syncing with the associated
node, it is easier to just use the volume controls of the associated node

This is mainly for security reasons. This way, we can limit the
permissions of wpexec without limiting wireplumber, for instance
with pipewire's default module-access, which limits apps based on
their executable name

Links between endpoints and device nodes are done externally in LUA

This is also what pulseaudio uses, so now the volumes in wpctl match what
pulseaudio tools report and they make a lot more sense from the user's POV

* Fixes set-volume & set-mute
* Re-enables volume & mute status printout for audio nodes

and optimize a little bit so that can stop iterating params
as soon as the info is known

Prints a table recursively with print()

This function loads and enables "api" plugins and makes them
available in the specified callback. This is intended to be used
by interactive scripts in order to get access to "api" plugins
such as the new "default-nodes-api" and "mixer-api"

This module provides an API to get/set volume controls on nodes,
using the same logic as pipewire-pulse, which means it will use
the device Route props when a node is associated with a device
that has this capability

Links items with media role set to existing endpoints. The target of the
endpoints is also configured.

Allows using the endpoint even if a target is not set.
