Reason for revert: Breaks perf tests. Original issue's description: > Extract bitrate allocation of spatial/temporal layers out of codec impl. > > This CL makes a number of intervowen changes: > > * Add BitrateAllocation struct, that contains a codec independent view > of how the target bitrate is distributed over spatial and temporal > layers. > > * Adds the BitrateAllocator interface, which takes a bitrate and frame > rate and produces a BitrateAllocation. > > * A default (non layered) implementation is added, and > SimulcastRateAllocator is extended to fully handle VP8 allocation. > This includes capturing TemporalLayer instances created by the > encoder. > > * ViEEncoder now owns both the bitrate allocator and the temporal layer > factories for VP8. This allows allocation to happen fully outside of > the encoder implementation. > > This refactoring will make it possible for ViEEncoder to signal the > full picture of target bitrates to the RTCP module. > > BUG=webrtc:6301 > > Committed: https://crrev.com/8f46c679d24a05b3f08e02c6d91ec9637f34e24f > Cr-Commit-Position: refs/heads/master@{#14998} TBR=stefan@webrtc.org,perkj@webrtc.org,mflodman@webrtc.org # Skipping CQ checks because original CL landed less than 1 days ago.
