Thomas Petazzoni 2c2fd3c257 package/ffmpeg: Add Kodi patchset
In the past xbmc delivered its own ffmpeg source code with specific patches to
address bugs found during the use of xbmc. For Helix the ffmpeg source code was
removed, Helix uses a vanilla ffmpeg source tarball and applies this patchset
on top of it.
