This CL moves GetAdaptUpTarget(), GetAdaptDownTarget() and ApplyAdaptationTarget() - and related code - to the VideoStreamAdapter. This includes pieces related to calculating how to adapt, including: - DegradationPreference - BalancedDegradationPreference - AdaptationRequest and last_adaptation_request_ - CanAdaptUpResolution() The VideoStreamAdapter's interface has changed: VideoSourceRestrictor methods are now hidden in favor of methods exposing AdaptationTarget. This CL also does some misc moves: - GetEncoderBitrateLimits is moved and renamed to VideoEncoder::EncoderInfo::GetEncoderBitrateLimitsForResolution. - EncoderSettings moved to a separate file. // For api/video_codecs/video_encoder.[cc/h] changes, which is the // moving of a function.
