I have a follow-up CL which plumbs the audio encoder factory all the way to
PeerConnectionFactory and also moves the requisite headers etc. into api/.

   # We allow .cc files in webrtc/api/ to #include a bunch of stuff
   # that's off-limits for the .h files. That's because .h files leak
   # their #includes to whoever's #including them, but .cc files do not
   # since no one #includes them.
