Jonas Oreland 6c7f98472e WebRTC-DeprecateGlobalFieldTrialString/Enabled/ - part 16/inf
This cl/ adds the feature actually injecting a FieldTrialsView into
PeerConnectionFactory, or into a PeerConnection or both.

The field trials used for a PeerConnection is those specified in
PeerConnectionDependencies. Otherwise will those from
PeerConnectionFactoryDependencies be used (and until we're finished with
this conversion, the global string fallback is used as last resort).

Note that it is currently not possible to create 2 FieldTrials
objects concurrently...due to global string,
so this cl/ is mostly (but entirely) for show, i.e one _can_
realistically inject them into a PeerConnectionFactory.
