Nit: Logs...

Done.

Since there is no more DebugEvent in the C-interface, I think we should remove
the DebugEvent message from the protobuf too. Not sure if that is best done in
this or a separate CL.

[ivoc, 2015/09/15 14:55:16]

I agree, let's do that in a follow-up CL.

 
   // Reads an RtcEventLog file and returns true when reading was successful.
   // The result is stored in the given EventStream object.
