edl: accept arbitrary paths

Browse Source 
Until now, .edl files accepted only "simple" filenames, i.e. no relative
or absolute paths, no URLs. Now that the origin bullshit is a bit
cleaned up and enforced in the EDL code, there's absolutely no reason to
keep this.

The new code behaves somewhat similar to playlists. (Although playlists
are special because they're not truly recursively opened.)

@ -254,6 +254,3 @@ header, the syntax is exactly the same. It's far more convenient to use ``;``
instead of line breaks, but that is orthogonal.
Example: ``edl://f1.mkv,length=5,start=10;f2.mkv,30,20;f3.mkv``
As a quirks, mpv will accept arbitrary paths in EDLs originating from
``edl://``, while ``.edl`` does not. This makes no sense.
