> A simple sdp parsing operation shouldn't be so difficult anyway

I find it a little disappointing to me that you cannot implement WHIP
without SDP parsing.

My knowledge of ICE is very superficial, but perhaps we could make the
data optional so that only the data available in the onicecandidate
callback is compulsory?  For example, we could say that:

  - ice-pwd is optional;

  - m-line is optional when mLineIndex is 0.

I'm perhaps wrong, but the ufrag should be enough to discriminate between
generations, and the m-line is not required if we're doing bundling.
