07633bdc6c Rename rtp_header_extension.h to rtp_header_extension_map.h
Move it to include path of the rtp_rtcp module to indicate it is ok to include it outside of the module.

Renamed to match the class it introduce and to reduce confusion with rtp_header_extensions.h

1476a9d789 Only compare sequence numbers from the same SSRC in ForwardErrorCorrection.
Prior to this CL, the ForwardErrorCorrection state would be reset whenever
the difference in sequence numbers of the last recovered media packet
and the new packet (media or FEC) was too large. This comparison did not
take into account that FlexFEC uses a different SSRC for the FEC packets,
meaning that the the state would be reset very frequently when FlexFEC
is used. This should not have led to any major problems, except for a
decreased decoding efficiency.

This CL verifies that whenever we compare sequence numbers in
ForwardErrorCorrection, they do indeed belong to the same SSRC.

0d1e27f00f desktopCapture: scale the cursor image according to screen scale factor on OSX
Before 10.12, OSX may report 1X cursor on Retina screen. (See crbug.com/632995.)
After 10.12, OSX may report 2X cursor on non-Retina screen. (See
crbug.com/671436.) So scaling the cursor if the image size doesn't meet the
expected size on either Retina or non-Retina screen.
Also corrects the cursor caching and change detection, so we can only do scalingat cursor changing for better performance.

As to screen capture on OSX, the captured frame already contains the current
cursor. So the MouseCursorMonitorMac is not needed for ScreenCapture for
performance purpose.

7a2862a933 Fix a bug in RtcEventLogSource
A recent change (https://codereview.webrtc.org/2855143002/) introduced
a bug in RtcEventLogSource::NextPacket(). The rtp_packet_index_ must
be incremented when a valid packet is found and delivered. Otherwise,
the same packet will be delivered over and over again.

The recent change also altered the way that audio packets are sifted out. Now, the RTP header is always parsed before discarding any non-audio packets. This means that RtpHeaderParser::Parse is always called, also with video packets, which sometimes contain padding. When header-only dumps (such as RtcEventLogs) are created, the payload is stripped, and the payload length is equal to
the RTP header length. However, if the original packet was padded, the
RTP header will carry information about this padding length, and the
parser will check that the pyaload length is at least the header +
padding. This is not the case for header-only dumps, and the parser will return an error. In this CL, we ignore that error when a header-only packet has padding length larger than 0.

8fbc765421 Ensure the RtcEventLog parser is backwards compatible
The old video send stream configs could contain multiple SSRCs and RTX SSRCs (in case of simulcast). To ensure that the RtcEventLog parser is backwards compatible, we have to return one config for every SSRC.

Also update the parsing functions for the other config types to return the config instead of passing in an output parameter.

6412e4c85f Drop the rtp_rtcp module's dependency on call.
Also deletes a couple of includes of call.h, which seem
unnecessary.

cff9dfdc4a FecControler disables FEC when *below* threshold
(This CL concerns both the PLR-based as well as the RPLR-based versions of FecController.)
1. Make FecController disable only when below the disabling-threshold, so as to prevent toggling when the enabling-curve and the disabling-curve are identical.
2. Extend unit-test coverage accordingly.
