[RFC] pipewire: update, add virtual session manager to pull in wireplumber without build cycle

[ahesford]

Note: This is not really intended as an update to 0.3.64; instead, if there is enough support for this proposal, I think #41846 should be merged with an INSTALL.msg warning people that pipewire-media-session will be dropped in the next release and that they should make sure they have a working wireplumber configuration before then.

pipewire will not work without a session manager; the previously included pipewire-media-session has long been deprecated and is now abandoned [1]. Making pipewire depend on wireplumber would create a cycle, so the cycle is broken with a rename and a new metapackage:

1. Rename pipewire -> pipewire-utils to clear the pipewire name
2. New pipewire meta depends on pipewire-utils and wireplumber

The rename is a violation of policy but allows existing pipewire users to see the new meta as an update that will pull in an updated real pipewire alongside the now-required wireplumber.

Continuing the work of #38521.

As per IRC discussion, we can avoid the rename and still break the cycle once #39868 is merged by declaring a pipewire-session-manager virtual that defaults to some dummy package like pipewire-session-manager-bootstrap with repository=bootstrap, than make wireplumber provide pipewire-session-manager.

I would prefer to avoid the renaming scheme if possible. Would the implementation of the alternate proposal make intuitive sense if you generally understand xbps templates?

Also, I recommend adding the following patch, which would replace pipewire-media-session with wireplumber in the default configuration files:

# Removes pipewire-media-session from default configs

This branch has been restructured to use a virtual package to break the pipewire-wireplumber build cycle that would otherwise appear. It should NOT be merged until #39868 is merged and we can add repository=boostrap to the pipewire-session-manager-boostrap template.

[ahesford]

I am not inclined to pull a patch that modifies default paths which seem only to appear in comments. Upstream should fix these paths if necessary because they made the decision to abandon pipewire-media-session and render these paths obsolete.
