de9e5fffa2 Add stats for frequency offset when converting RTP timestamp to NTP time. 
- Add histogram: "WebRTC.Video.RtpToNtpFreqOffsetInKhz"

  The absolute value of the difference between the estimated frequency during RTP timestamp to NTP time conversion and the actual value (i.e. 90 kHz) is measured per received video frame. The max offset during 40 second intervals is stored. The average of these stored offsets per received video stream is recorded when a stream is removed.

Updated rtp_to_ntp.cc:
- Add validation for only inserting newer RTCP sender reports to the rtcp list.

- Move calculation of frequency/offset (from RTP/NTP timestamp pairs) to UpdateRtcpList. Calculated when a new RTCP SR in inserted (and not in RtpToNtpMs per packet).

d56d68cd27 system_wrappers: Fix include header guards. 
This should have been a part of https://codereview.webrtc.org/1413333002/

The header guard PRESUBMIT rule is being enabled in
https://codereview.webrtc.org/1419203005 so things like this won't
happen in the future.
