a1b4eb2196 generateKeyFrame: add rids argument
and do the resolution of rids to layers. This has no effect yet
since the simulcast encoder adapter (SimulcastEncoderAdapter::Encode), the VP8 encoder (LibvpxVp8Encoder::Encode) and the OpenH264 encoder (H264EncoderImpl::Encode) all generate a key frame for all layers whenever a key frame is requested on one layer.

28e9653b1f Remove dependency on RtpVideoSenderInterface from EncoderRtcpFeedback.
This removes the two step initialization and explicit circular
dependency between the sender and the observer that complicates
construction and making members const that should be.
Moving forward the encoder feedback instance will move to a different
class, so this CL is one part of making that change possible.

Also removing an unnecessary mutex and replacing with a checker.

git grep -l " testing::" | xargs sed -i "s/ testing::/ ::testing::/g"
git grep -l "(testing::" | xargs sed -i "s/(testing::/(::testing::/g"

After this, two .cc files failed to compile and I have fixed them
manually.

14d1c9d968 Rename EncoderKeyFrameCallback back to EncoderRtcpFeedback
The name EncoderRtcpFeedback is more appropriate because:
1. "Callback" implies a single function exposed, which is
   not the case.
2. We intend to add OnLossNotification() to the same class.

d1f7eb6e83 Postpone setting of CpuOveruseOptions.
This will enable changing thresholds when switching between hardware
and software encoders. It is also a partial revert of
https://webrtc-review.googlesource.com/33340: construction of the
OveruseFrameDetector is still in VideoSendStream, but configuration is
moved back to VideoStreamEncoder.

Longer term, information about HW vs SW, or generally, about resources
consumed by the encoder, should be passed in the per-frame callbacks
to OveruseFrameDetector, and then the CpuOveruseOptions could move
back to construction time.

bc900cb1d1 Move rtp-specific config out of EncoderSettings.
In VideoSendStream::Config, move payload_name and payload_type from
EncoderSettings to Rtp.

EncoderSettings now contains configuration for VideoStreamEncoder only,
and should perhaps be renamed in a follow up cl. It's no longer
passed as an argument to VideoCodecInitializer::SetupCodec.

The latter then needs a different way to know the codec type,
which is provided by a new codec_type member in VideoEncoderConfig.
