Doesn't this need USE_QUIC or HAVE_QUIC as well (and the class reference above)?

It's possible that this is NULL when it's needed. So you need an equivalent of
DataChannelProviderInterface in order to tell a QuicDataChannel when the
underlying transport channel is created or destroyed.

 
   // Called when voice_channel_, video_channel_ and data_channel_ are created
   // and destroyed. As a result of, for example, setting a new description.
