platform-external-webrtc/pc/rtcstats_integrationtest.cc
Henrik Boström b619936dee Stats traversal algorithm added. 
This is part of the work to add a selector argument to getStats().

Changes:
- TakeReferencedStats() added, which traverses the stats graph and takes
  any stats from the report that are directly or indirectly accessible
  from the starting stats objects in the stats graph. The result is
  returned as a stats report.
- GetStatsReferencedIds(), an efficient helper function for getting
  neighbor stats object IDs.
- RTCStatsReport::Take(), removed the stats object with the given ID and
  returns ownership of it (so that it can be added to another report).

TakeReferencedStats() is tested with a bunch of sample stats graphs.

GetStatsReferencedIds() is tested in the rtcstats_integrationttest.cc,
making sure the expected IDs are returned. The expected IDs are the
values of the stats object members with the "Id" or "Ids" suffix.
