This is a mechanical change since it affects so many files. I420VideoFrame -> VideoFrame and reformatted. Rationale: in the next CL I420VideoFrame will get an indication of Pixel Format (I420 for starters) and of storage type: usually UNOWNED, could be SHMEM, and in the near future will be possibly TEXTURE. See https://codereview.chromium.org/1154153003 for the change that happened in Cr. BUG=4730, chromium:440843 R=jiayl@webrtc.org, niklas.enbom@webrtc.org, pthatcher@webrtc.org Review URL: https://webrtc-codereview.appspot.com/52629004 Cr-Commit-Position: refs/heads/master@{#9339}
