Audacious 3.5 entering Rawhide

[Michael Schwendt]

With the fresh release of Audacious 3.5 final [1], I'm going to push this
new release also to Rawhide. It has been available via Copr [2] since
alpha1 already, and although I've not received any user feedback on the
pre-releases at all, I've evaluated it personally and also followed
upstream activity.

Relevant for the Fedora packages:
 - plugin package rebuilds will be needed due to a new Plugin API version
 - the Plugin API version has moved into header api.h, so package spec
   files that grep the version need to be adjusted
 - the API changes may require minor modifications to external plugins

I'll rebuild xmp-plugin-audacious as necessary unless there will be
a request not to do that yet.
