I'm guessing because the API change is binary compatible.
vorbis_encode_ctl has been around before. It's a "swiss army knife"
function similar to ioctl; you give it a function number and a generic
pointer to a parameter structure. The new version has new function
numbers, and the old ones are deprecated in favor of the new ones, but
the old ones still work.
