Revert of FrameBuffer for the new jitter buffer. (patchset #9 id:160001 of https://codereview.webrtc.org/1969403007/ )
Reason for revert:
Two tests added by this CL failed in Win DrMemory Full:
TestFrameBuffer2.OneLayerStreamReordered - TestFrameBuffer2.WaitForFrame
See the link here:
https://build.chromium.org/p/client.webrtc/waterfall?builder=Win%20DrMemory%20Full
