Overview
Comment:Remove extraneous class wrapper action.action. Start to regroup listformat mapping (pls-url → m3u-fn rewrites). Will need some heuristics, as depending just on the channel.listformat assumption won't work in practice (some .pls servers actually host direct server links, or occasionally .m3u references even). Currently does nothing, just returns the pls/etc URL.

Consolidate listformat types to just "pls", "m3u" and "srv". Probe for direct ICY server contact in action.playlist_convert(), unify extraction methods. check-in: 85313637a3 user: mario tags: action-mapfmts

# Each channel plugin has a .listtype which describes the linked

# but sometimes url/direct if the entry[url] directly leads to the
# streaming server.
#
# As fallback there is a regex which just looks for URLs in the
# given resource (works for m3u/pls/xspf/asx/...). There is no
# given resource (works for m3u/pls/xspf/asx/...).
