log but process. From fippo/rtcstats#19:

• c= line in any SDP
• a=rtcp line in any SDP
• a=candidate line in any SDP
• any onicecandidate / addIceCandidate event
• getStats

hrm. I just looked at webrtc-internals dumps and it looked like they only put the two higher bytes. Can you check @ggarber? Would solve the getStats problem at least.

     "endTime": "2016-04-15T08:54:03.919Z",
     "values": "[52.58,52.58

not sure whether this is in getstats or the webrtc-internals dump...

turns out to be a bug in webrtc-internals: https://bugs.chromium.org/p/chromium/issues/detail?id=605046

note: I want ip addresses in relay candidates to identify the turn server used
