This CL is partly a test to see if there's an impact on binary size:
- Not a big difference for binaries (decrease): -776b to -4Kb
- For libraries (libwebrtc.a) it actually increases the size: +40Kb
Secondarily this CL is basically to introduce this pattern to the
code base. In terms of LOC, this makes things slightly more compact.
From:
class Foo {

To:

This makes "WebRTC-AllowDisablingLegacyScalability" enabled-by-default,
meaning any app can opt-in to spec-compliant simulcast when
scalabilityMode is specified.
The opt-in criteria is also made more restricitve: you now have to
specify both scalabilityMode and scaleResolutionDownBy to get simulcast,
otherwise you continue to get legacy "single stream" path.
The reason for this is not to cause any surprises in use cases like
[{scalabilityMode:"L1T1", active:true}, {active:false}, {active:false}]
In cases like this where scaleResolutionDownBy is not specified, it
defaults to 4:2:1 if simulcast is used but the legacy path caps it to
one stream, meaning full resolution. By restricing simulcast only to
cases that set scaleResolutionDownBy, we remove the risk of an app
getting a different resolution than expected due to opt-in.

Attempting to ship "WebRTC-AllowDisablingLegacyScalability" revealed a
DCHECK that happens when negotiating 3 VP9 streams prior to the
setParameters() call:
1. By default, `scalability_mode` is missing, so those 3 streams
defaulted to legacy SVC, meaning only a single stream is used.
2. Then, setParameters() was called to make
`encodings[0].scalability_mode = "L2T2_KEY"` and
`encodings[1-2].active = false`. The inactive streams were just
dummies and never expected to exist.
Without simulcast support this is OK, because both 1) and 2) are
interpreted to have a single stream. But with simulcast support, 1) is
interpreted as single stream and 2) as three streams (1 active, 2
inactive). This should be roughly the same setup, but our code treats
them differently.
The DCHECK crash was a mismatch in number of streams in one of the
layers.
The fix is to re-create the streams when the number of streams change
for this reason. The new test revealed other issues and fixes too:
- Support for multiple spatial layers (e.g. "L2T2_KEY") when multiple
encodings exist but only one encoding is active.
- Allow inactive layers not to have a scalability mode set.
A laundry list (https://crbug.com/webrtc/15028) has been created to
update known places doing "if streams == 1" that need to do "if
active streams == 1" instead.

The goal of the VP9 simulcast project is that when `scalability_mode`
is set, multiple encodings are always interpreted as simulcast, even
if VP9 or AV1 is used. This CL makes this so, but only if the flag
"WebRTC-AllowDisablingLegacyScalability" is "/Enabled/". This allows us
to make "SendingThreeEncodings_VP9_Simulcast" EXPECT VP9 simulcast.
When we are ready to ship we will remove the need to use the field
trial, but before we ship this we'll want to revisit if
SvcRateAllocator can be updated to support simulcast. (Today if we use
SvcRateAllocator when VP9 simulcast is used, all encodings except the
first one get bitrate=0, causing the test to fail because media is not
flowing on all layers.) For now, a TODO is added.

This CL updates EncoderSimulcastProxy to respect this info to avoid

Alternatively we can try to get rid of EncoderSimulcastProxy altogether

As part of go/unblocking-vp9-simulcast (Step 1), EncodedImage is being
upgraded to be able to differentiate between what is a simulcast index
and what is a spatial index.
In order not to break existing code assuming that "if codec != VP9,
SpatialIndex() is the simulcast index", SimulcastIndex() has fallback
logic to return the value of spatial_index_ in the event that
SetSimulcastIndex() has not been called. This allows migrating external
code from (Set)SpatialIndex() to (Set)SimulcastIndex(). During this
intermediate time, codec gates are still necessary in some places of
the code, see TODOs added.
In a follow-up CL, after having fixed dependencies, we'll be able to
remove the fallback logic and rely on SimulcastIndex() and
SpatialIndex() actually being the advertised index and "if codec..."
hacks will be a thing of the past!

This is done by allowing implementations of AudioDeviceModule to
implement the GetStats() method. The default implementation returns
nullopt, in which case RTCAudioPlayoutStats will not be visible in the
stats.

Fallback to a default value if the scalability mode is unset or not supported by the codec.
The fallback logic is only enabled if the scalability mode is configured for any of the encodings for now (i.e. initial default values are not set).

With this cl, a packet is only parsed once in RtpTransport::DemuxPacket and the metadata is reused.
Extensions are still identified twice- one for demuxing based on mid. The second time in Channel::OnReceivedPacket in order to use extensions specific to that mid.

This is a reland of commit 81aab488781c1a736c9d85ff1532631be2989523
See diff between Patch Set 1 and latest Patch Set.
The original CL broke this WPT[1] because getStats() with the receiver
as the selector stopped working in the event of unsignalled SSRCs due
to the receiver not knowing what the SSRC was.
This fix is to query media_channel_ for the unsignalled SSRC in the
event that the receiver does not know the SSRC.

Original change's description:
> Remove 'trackId' dependency in stats selector algorithm.
>
> In preparation for the deletion of deprecated 'track' stats, the
> stats selector algorithm needs to be rewritten not to use 'trackId'.
>
> This is achieved by finding RTP stats by their SSRC, as obtained via
> getParameters(). This unfortunately adds a block-invoke (in the sender
> case the block-invoke happens inside GetParametersInternal and in the
> receiver case the block-invoke is explicit at the calling place), but
> it can't be helped and it's just once per getStats() call and only if
> the selector argument is used.
