Left shifting a negative value results in undefined behaviour. It is safer to
multiply in this case.

Added playout-delay RTP header extension for video to JsepSessionImpl::SetupDefaultRtpExtensions.
This ensures that this extension will be preserved when generating an answer to an offer (by a sending peer) containing it.
Also updated JsepSessionTest to include a test verifying that the expected default audio and video extensions are set.

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.

If there are multiple pending queries, this allows up to five of them to be
sent in a single packet. This also adds a check to ensure we don't already have

We need to join the multicast group on all network interfaces or we may end up
missing packets. There is a limit on the number of groups joinable by a single
socket (20 on my Linux system) but it doesn't seem worth worrying about
hitting that limit at the moment as it seems unlikely that many users would
have more than 20 network interfaces on a system on which they are running
Firefox.

I've reworked the includes in most of the files I've touched since I was adding
GMPLog.h:
- Reordered the includes to better match the Google C++ style.
- Removed includes that are already included from the associated header or
GMPLog.h. I.e. if Foo.cpp includes Foo.h, and Foo.cpp includes other headers
already included in Foo.h, these were removed.

This patch changes instances where the GMP MOZ_LOG is used to prefer using
macros from GMPLog.h:
- Files that don't need their own macros now just directly call
`GMP_LOG_<LEVEL>` as required.
- Files that use their own macros for formatting have had those macro
definitions changes so that the macros have unique names and are expressed in
terms of the macros from GMPLog.h.
I've also made a couple of drive by edits to logs so that they log more than a
couple of words and updated some strings where the incorrect class name was
being logged.
