Originally RtcEventProbeClusterCreated was logged in bitrate prober. This means that anyone who was using GoogCcNetworkControl wasn't logging it, and the NetworkControl wasn't self-contained.
This changes moves the responsibility for logging ProbeClusterCreated to ProbeController (where the probe is created), it also moves the responsibility for assigning probe ids to the probe controller.

PeerConnection::Close() is, per-spec, a blocking operation.
Unfortunately, PeerConnection is implemented to own resources used by
the network thread, and Close() - on the signaling thread - destroys
these resources. As such, tasks run in parallel like getStats() get into
race conditions with Close() unless synchronized. The mechanism in-place
is RTCStatsCollector::WaitForPendingRequest(), it waits until the
network thread is done with the in-parallel stats request.
Prior to this CL, this was implemented by performing
rtc::Thread::ProcessMessages() in a loop until the network thread had
posted a task on the signaling thread to say that it was done which
would then get processed by ProcessMessages(). In WebRTC this works, and
the test is RTCStatsIntegrationTest.GetsStatsWhileClosingPeerConnection.
But because Chromium's thread wrapper does no support
ProcessMessages(), calling getStats() followed by close() in Chrome
resulted in waiting forever (https://crbug.com/850907).
In this CL, the process messages loop is removed. Instead, the shared
resources are guarded by an rtc::Event. WaitForPendingRequest() still
blocks the signaling thread, but only while shared resources are in use
by the network thread. After this CL, calling WaitForPendingRequest() no
longer has any unexpected side-effects since it no longer processes
other messages that might have been posted on the thread.
The resource ownership and threading model of WebRTC deserves to be
revisited, but this fixes a common Chromium crash without redesigning
PeerConnection, in a way that does not cause more blocking than what
the other PeerConnection methods are already doing.
Note: An alternative to using rtc::Event is to use resource locks and
to not perform the stats collection on the network thread if the
request was cancelled before the start of processing, but this has very
little benefit in terms of performance: once the network thread starts
collecting the stats, it would use the lock until collection is
completed, blocking the signaling thread trying to acquire that lock
anyway. This defeats the purpose and is a riskier change, since
cancelling partial collection in this inherently racy edge-case would
have observable differences from the returned stats, which may cause
more regressions.

This function is used to post messages onto rtc::Threads. The thread
invokes the functor without blocking the calling thread. Messages posted
in this way are executed in the order that they were posted. This is
meant to work as the equivalent of "thread->PostTask()" in Chromium.
Note: AsyncInvoker currently does something similar but it is more
cumbersome to use (somebody has to create it and own it and make sure
not to destroy it while tasks are pending or else they're cancelled). It
also comes with a fundamental flaw: You cannot destroy the AsyncInvoker
from within the functor (this results in a neverending Wait). This makes
the AsyncInvoker not suitable for implementing "destructor traits"
amongst other things.
This CL will allow us to easily add "PostTask()" to rtc::Thread or add
support for DestructorTraits, which is especially useful when you have a
reference counted object that is referenced from multiple threads but
owns resources that has to be destroyed on a particular thread.
Blocking invokes are forbidden in Chromium but WebRTC performs them
frequently. Being able to perform the equivalent of PostTask() is a
good thing.

This change adds incoming & outgoing packet rates to the
event_log_visualizer.
The outgoing packet rate is drawn on the graph with outgoing RTP rate,
because we want to see it together with bandwidth estimate and probe
clusters.
The incoming packet rate is drawn separately.
