* Roll webrtc & libjingle 6346:6352.
* Take remote track's cricket::VideoFrame's elapsed time as media::VideoFrame's timestamp. This elapsed time is computed from the remote video frame's rtp timestamp and starts from 0.
* Use media::VideoFrame's timestamp as video element's currentTime instead of normalize it to 0 everytime. This is to ensure video elements connected to the same track have the same currentTime.

TEST=manually add local and remote mediastreams to different video tags and check the current time
