Parse metadata blocks when handling unparsed flac in push mode. This works around a bunch of issues with the flac decoder when handling metadata blocks that are larger than the max. flac framesize, which coverart blocks often are. We need to have all the data for these blocks available when we pass data to libflac. http://gstreamer-devel.966125.n4.nabble.com/Flac-files-that-will-playback-but-not-stream-td3338198.html#a3395276 https://bugzilla.gnome.org/show_bug.cgi?id=566769
