The original landed cl is in patchset 1. The following patchset fix VideoQualityTest as well as fix the case where max_bitrate is set in the SendParams. A unit test is added for that as well. Original cl description: Let ViEEncoder handle resolution changes. This cl move codec reconfiguration due to video frame size changes from WebRtcVideoSendStream to ViEEncoder. With this change, many variables in WebRtcVideoSendStream no longer need to be locked.
