This CL adds [[deprecated]] to the old signatures, and uses the new
signatures throughout.

a9d5141367 Rename cricket::RtpParameters and derived classes
Renames
  cricket::RtpParameters
to
  cricket::MediaChannelParameters
in order to distinguish it better from webrtc::RtpParameters.
This involves renaming
  RtpSendParameters -> SenderParameters
  AudioSendParameters -> AudioSenderParameters
  AudioRecvParameters -> AudioReceiverParameters
  VideoSendParameters -> VideoSenderParameters
  VideoRecvParameters -> VideoReceiverParameters

875cd32eac Fix inconsistency with x-goog-max-bitrate and maxBitrate.
In the past, only encodings.size() == 1 was considered singlecast. But
it's possible to have singlecast via {active,inactive,inactive} too so
this condition should be updated.

This CL ignores x-goog-max-bitrate if maxBitrate was specified on *any*
encoding. This fixes the case of {active,inactive,inactive} resolving
the singlecast inconsistency, but it also takes things one step further
and ignores x-goog-max-bitrate in simulcast cases as well (if any
active encoding has a maxBitrate), as it is not clear why simulcast
should behave differently from singlecast with regards to this flag.

b90cd91983 Fix first encoding's maxBitrate being ignored when scalability is set.
EncoderStreamFactory has two code paths for creating a stream: the
"simulcast path" and the "default path". Only the former cares about
encoding paramter's maxBitrate. The latter assumes that
`encoder_config.max_bitrate_bps` already encompasses the maxBitrate of
the first encoding, but this is not always the case.

As of M113, when scalability mode is specified, {active,inactive} does
not count as simulcast stream but as a default stream represented by
encoding[0].

The problem is that `encoder_config.max_bitrate_bps` only includes
`encodings[0].max_bitrate_bps` when `encodings.size() == 1` which isn't
the case here.

This CL fixes the problem by making the "create default stream" code
path look at the first encoding's maxBitrate and remove existing
assumptions that `encoder_config.max_bitrate_bps` encompasses
`encodings[0].max_bitrate_bps`. This is a step in the right direction
since we're trying to remove all special cases and have encodings map
1:1 with SSRCs, so the "max bps of entire stream" should indeed be a
separate limit than the per-encoding limits and it was confusing that
sometimes it included and sometimes it excluded encoding[0]'s limit.

This issue did not happen in {inactive,active} since that code path
counts as "simulcast stream", so "default stream" is only ever
applicable for index 0.

TESTED=Simulcast Playground, see https://crbug.com/1455962.

0145db4091 Recreate the stream when switching from standard to legacy API.
ReconfigureEncoder() is supposed to recreate the send stream when
switching between legacy and standard API paths to ensure that the
upper and lower layers agree on the number of streams that exist
(legacy = 3 encodings but 1 stream, standard = same as encodings).

This successfully happened when going from standard to legacy but due
to a bug in the condition this did not happen when going from legacy to
standard because `scalability_mode_used` is always false here (even
though the standard path does use a scalability mode).

As a consequence, SetRtpParameters()'s call to UpdateSendState()
resulted in a DCHECK-crash. In release builds we still avoid IOOB
because active_modules.size() < rtp_streams.size() but to avoid mistakes
like this happening again in the future, the DCHECK is promoted to a
CHECK.

The fix is to remove the scalability mode condition which didn't make
sense anyway - changing scalability mode does not require recreation but
recreation is necessary when number of streams change, whether or not
scalability mode changed.

TESTED = Using Simulcast Playground and switching back and forth
between standard and legacy and changing scalability modes and
confirming from stats, see https://crbug.com/1467455.

97c9623839 Make a shim object implementing the VideoMediaChannel interface
The intent is that this object can be used instead of VideoMediaChannel,
clearing the way for decomposing VideoMediaChannel into send and
receive classes.

This CL uses it for the "both" role of WebRtcVideoEngine::CreateMediaChannel; a later CL will use it for all roles on all engines.

621cb2943d Fix video version of RTCInboundRtpStreamStats.jitterBufferDelay to obey spec.
Prior to this CL, the video `jitterBufferDelay` stat was the accumulated current delay, which is a smoothened version of the target delay. This is not correct according to the spec [1]. Rather, the stat should be the accumulated time spent in the jitter buffer, for all emitted frames. This CL fixes this spec compliance problem.

Expect changes to test metrics and product monitoring as this CL rolls out.

[1]: https://www.w3.org/TR/webrtc-stats/#dom-rtcinboundrtpstreamstats-jitterbufferdelay

Tested:
1. Go to https://jsfiddle.net/jib1/0L6duga2/show
2. Apply 2.0 seconds of video delay.
3. Notice that "Video jitter buffer delay" is slightly less than 1990ms. (2000ms playoutdelayhint - 10ms render delay - Xms decode delay).

via the SetReceiverFeedbackParams function.

This CL adds caching those parameters so that they are applied
to receive streams created after the SetReceiverFeedbackParams call.

e90d9344b8 Delete the WebRTC-H264Simulcast/Disabled/ field trial.
The field trial has been enabled-by-default for several years, I
suspect it was needed during its development but there doesn't seem to
be any reason to maintain it going forward.

Its very existence blocks our long term objective to have our APIs
behave according to the W3C standards and any apps still depending on
it, if there are any, should make sure to use the APIs correctly
instead. I assume they already do any any references to this is us
forgetting to clean things up.

e32b6228d3 RtpTransportControllerSend::ProcessSentPacket: remove PostTask.
This CL removes a PostTask in response to packet receipt reception.
This is made possible due to PacketRouter lock removal in
https://webrtc-review.googlesource.com/c/src/+/300964.

Depending on how transport code is organized, this may lead to
possibility of packet receipts arriving in
RtpTransportControllerSend which may re-enter the PacingController's
ProcessPackets method, leading to out-of-order packet sends. Fix
this by detecting re-entry and avoiding a second ProcessPackets call
in the TaskQueuePacedSender.

c8c4a282a6 Introduce support for video packet batching.
This CL introduces a new feature enabling video packet send batches.
The feature is enabled via
PeerConnectionInterface
::RTCConfiguration
::MediaConfig
::enable_send_packet_batching.

PacketOptions have been augmented with attribute "batchable" (set for
all video packets) and attribute "last_packet_in_batch" which gives
injected AsyncPacketSockets a chance to understand when a batch begins
and ends.

When the feature is on, packets are collected in RtpSenderEgress. On
reception of OnBatchComplete from PacingController, RtpSenderEgress
sends the collected batch, setting "last_packet_in_batch" to true
in the last packet.
