This avoids creating the playlist from the UI mainloop, which is not
typically a good idea.

pl_Get() does not create a reference to the playlist, so nothing is
leaked if the result is ignored. Calling pl_Get() ensures that the
playlist has been created.

Overwriting *fmt is safe nowadays.

Close #6105

Due to mismatched "resource" and "hold" locks, this introduced a race
where more than one audio output gets created.

This reverts commit 4e57bd05.

This should make volume work.
Patch welcome to make hardware volume work instead where available.

Before setup(), opaque is not defined.

xdg-screensaver has higher priority, so xscreensaver was never used.

When the service is absent, the error message is NULL anyhow.
