c69385de8b Add |protected_by_flexfec| flag to VideoReceiveStream::Config.
Use of FlexFEC is known when streams are created in
WebRtcVideoChannel2, so this replaces the code in Call to infer
FlexFEC config of video streams from the configuration of the FlexFEC
stream(s). This also allows us to switch to a more logical creation
order, where media streams are created before the FlexFEC stream.

This is done in preparation for a larger refactoring of the RTP
demuxing done in Call.

0c4b849b27 Pick a matching CN codec, rather than the first CN codec.
It seems to me that we're currently just picking the first CN codec, rather than the one that matches the clock rate of the voice codec. The only test I've gotten to fail by changing this behavior is the one that's also changed in this CL, which explicitly expects a CN codec to be chosen even though there's none matching.

340e3fd59f Split FlexFEC field trial in two.
- The "flexfec-03" codec is advertised in the SDP whenever the
  "WebRTC-FlexFEC-03-Advertised" field trial is enabled.
- Sending FlexFEC packets is enabled whenever the "flexfec-03" codec is
  negotiated, and the "WebRTC-FlexFEC-03" field trial is enabled.

After this CL, the number of calls to
WebRtcVideoChannel2::WebRtcVideoSendStream::SetCodec during renegotiation
will be reduced for cases when only one endpoint has the "WebRTC-FlexFEC-03"
field trial enabled.

off, and later ReconfigureEncoder() is called updating the configuration
but not the encoder instance, causing an inconsistency in the encoder's

The current method with max_pixel_count and max_pixel_count_step_up,
where only one should be used at a time and this first signaling an
inclusive upper bound and other other an exclusive lower bound, makes
for a lot of confusion.

I've updated this to have a desired target and a maximum instead. The
source should select a resolution as close to the target as possible,
but no higher than the maximum.

I intend to also add similar frame rate settings in an upcoming cl.

These structs will be used for ORTC objects (and their WebRTC
equivalents).

This CL also introduces some minor changes to the existing implemented
structs:

- max_bitrate_bps uses rtc::Optional instead of "-1 means unset"
- "mime_type" turned into "name"/"kind" (which can be used to form the
  MIME type string, if needed).
- clock_rate and channels changed to rtc::Optional, since they will
  need to be for RtpSender.send().
- Renamed "channels" to "num_channels" (the ORTC name, which I prefer).

9d58d94585 Fix and improve FlexFEC configuration for RTP/RTCP.
Fix: Order of assignments is now correct, after being incorrect
due to an incorrect merge between
https://codereview.webrtc.org/2617373002/ and
https://codereview.webrtc.org/2589713003.

Improvement: Set parameters in more places, allowing for
correct reconfiguration. Add TODOs to point of minor issues
with current configuration.

TESTED=By locally patching an application using this code.

35fc2aa82f Revert of Drop frames until specified bitrate is achieved. (patchset #12 id:240001 of https://codereview.webrtc.org/2630333002/ )
Reason for revert:
due to failures on perf tests (not on perf stats, but fails running due to dcheck failures), see e.g., https://build.chromium.org/p/client.webrtc.perf/builders/Android32%20Tests%20(K%20Nexus5)

Original issue's description:
> Drop frames until specified bitrate is achieved.

> This CL fixes a regression introduced with the new quality scaler

> code that compares incoming captured frames to the target bitrate,
> and if they are found to be too large, they are dropped and sinkWants
> set to a lower resolution. The number of dropped frames should be low
> (0-4 in most cases) and should not introduce a noticeable delay, or
> at least should be preferrable to having the first 2-4 seconds of video
> have very low quality.

83399caec5 Drop frames until specified bitrate is achieved.
This CL fixes a regression introduced with the new quality scaler
where the video would no longer start in a scaled mode. This CL adds
code that compares incoming captured frames to the target bitrate,
and if they are found to be too large, they are dropped and sinkWants
set to a lower resolution. The number of dropped frames should be low
(0-4 in most cases) and should not introduce a noticeable delay, or
at least should be preferrable to having the first 2-4 seconds of video
have very low quality.

fb45c6c103 Inform jitter buffer about FlexFEC protection.
This CL introduces a way for the VideoReceiveStreams to check whether
they are protected by any FlexfecReceiveStreams. This is done in the
VideoReceiveStream::Start() method, which then propagates this information
down to the jitter buffer adaptation logic.
