There is a window inside of SendPacket where the critical section is released
which means that other code could set paused_. This would lead to us hitting
the assertion at the top of SendPacket. Checking paused_ in the while loop
will avoid this. Upstream has fixed this problem in a similar way, but the
code has changed there enough that it doesn't make sense to try to bring in
their fix directly.

This is a partial cherrypick of https://webrtc.googlesource.com/src/+/f89110d67902e787f6745ad2b52f7f09fc808512.
The cropping changes in that revision are problematic on our version of webrtc.org and
result in distorted video, which looks as though there is a stride problem. This takes
the change to try to use PW_RENDERFULLCONTENT and to fall back to the current code if
that fails. This fixes capturing Chrome windows and allows Firefox to properly capture
its own window.
Using PW_RENDERFULLCONTENT can adversely affect performance. Using the
CroppingWindowCapturer can avoid using the WindowCapturer in some circumstances and so
result in better performance. Bug 1586071 tracks switching to the
CroppingWindowCapturer.

This change mainly removes the `mTracks` member from MediaStream and moves all
associated members up a level, so that a MediaStream in practice represents a
single track.
Classes will be renamed in a future patch to reflect this.
Other changes include:
The new `mEnded` member of MediaStream changes meaning to only become true when
all data in the stream has been processed. It stems from
StreamTracks::Track::mEnded which used to become true as soon as the last bit of
data had been added to a track, and there could still be data in the track that
would get processed in future iterations. We are moving towards not having any
future data in tracks, which is why this change is ok to make -- keeping the old
behavior will soon not make sense.
TrackUnionStream is changed to no longer take a list of streams as input and
forward the union of their tracks to itself. Instead it's limited to having one
track as input at a time.
The autofinishing functionality that TrackUnionStream had before has been
transformed into an autoending functionality to allow it to defer ending until
its been told that it's ok to end through the control API. This lets a single
TrackUnionStream span the lifetime of multiple inputs, which will be useful for
making DecodedStream spec compliant with HTMLMediaElement::CaptureStream(), and
for implementing the currently discussed MediaRecorder::ReplaceTrack(), to name
a few potential use cases.
AudioNodeStreams used to only have a track (and thus an AudioSegment) if the
EXTERNAL_OUTPUT flag was enabled on them. With all MediaStreams now representing
a track, AudioNodeStreams inherently have an AudioSegment as a member. It is
however only used with data if the EXTERNAL_OUTPUT flag is enabled.

This adds a reference counted implementation of Telemetry::AutoTimer for use
in timing WebRTC calls. The telemetry is recorded when the reference count goes
from one to zero. This allows capturing the total call duration, rather than
the duration of individual PeerConnections. The timers are stored in a
HashTable, indexed by the Document URI, allowing for call durations to be
calculated individually for separate pages.
This reuses the existing WEBRTC_CALL_DURATION telemetry key. This means we
won't be able to compare telemetry from versions of Firefox with this change
to versions of Firefox without this change. The reason for making this change
is that the telemetry is not very useful in its current form, so I think it
makes sense to do this rather than adding a new key.

We need to join the multicast group on all network interfaces or we may end up

The Telemetry::AccumulateTimeDelta function reports in milliseconds but I had
assumed seconds when I added the hostname obfuscation ICE duration histogram.
This change adjusts the "high" value accordingly.
With the telemetry we've collected to date, 60% of the values are below 600
milliseconds, so I think that setting a high value of 30 seconds should be
sufficient even if there is a long tail. Since this does not change the data
being collected, no additional data-review is required, but it does require
renaming the key.

Freeing the conduits when the transceiver is stopped releases all of the

On my system, with an opt+debug build and 200 stopped transceivers, I see
373.17 MB of memory use in the content process without this patch, and
158.93 MB of memory use with this patch applied.
Going further and calling Shutdown_m as part of Stop() reduces the memory
use to 157.98 MB, which seems like a marginal improvement at the cost of
a much larger risk of introducing bugs.
