output/raop: delete the RAOP plugin
This plugin is horrible code, I mean it. Last year, I tried hard to fix it, but I figured would take less time to do a full rewrite. Given that I don't even have any device that supports RAOP, I can't do that properly. After 16 months, nobody volunteered for fixing it. Hereby, I delete it, because having no RAOP plugin is better than having this mess. Sorry.
