Well, we clearly can't choose an extension based on the codec used
during muxing, but we can make libavformat default to flac when no
codec is specified and oga output is requested, much like we do
with Speex when using .spx and Opus when using .opus, both also
non enforced recommendations.
It's not like it forbids the use of other codecs, like it evidently
happens with video codecs in patch 3.
