This cl/ fixes a race condition with the recent additions
to NetworkMonitorAutoDetect (getAllNetworksFromCache).
The getAllNetworksFromCache-feature uses the by the Android team preferred way of
enumerating networks, i.e to register network listeners.
This however introduces a unpleasant race condition like this:
1) network.cc discover rmnet0
2) BasicPortAllocator tries to create UDP port on rmnet0
- This fails as BindSocketToNetwork requires a android handle.
3) NetworkMonitorAutoDetect gets callback with rmnet0
4) BasicPortAllocator tries to create TCP port on rmnet0
- This succeeds.
5) Since rmnet0 has one working port, there will not be
any new ports created on that network
=> We end up with a TCP only connection :(
---
By impl. IsAdapterAvailable, we make sure that the network
will not be used by BasicPortAllocator (or anyone else!)
until we support binding to it.
The IsAdapterAvailable was implemented for IOS,
and has test coverage using FakeNetworkManager.
This cl/ is default enabled with the kill-switch
WebRTC-AndroidNetworkMonitor-IsAdapterAvailable.

Because rtc::Thread inherits from TaskQueueBase, it already implements
a pair of PostTask/PostDelayedTask methods that we want to keep. But in
addition to those, rtc::Thread defines its own PostTask/PostDelayedTask
using templates. These are the versions that we want to deprecate.
They were originally implemented prior to rtc::Thread inheriting from
TaskQueueBase. We want to deprecate them because...
- We don't want to have multiple code paths that do the same thing.
- We want to move away from rtc::Thread to TaskQueueBase long-term.
- These versions are not overridable in Chromium.
- These versions don't have high/low precision versions of PDT.
Helper methods are added to rtc::Thread so that callers don't have to
wrap every lambda in webrtc::ToQueuedTask() and update dependencies.

The default value of sdpSemantics is about to change from PLAN_B to

This is in accordance to the publically announced plans:

While we're at it, we're upgrading almost all unit tests to use Unified

Before this change HardwareVideoEncoder used capture time as frame
timestamp passed to HW encoder. That led to buffer overshoots with
HW encoders which infer frame rate from timestamps when frames were
dropped before encoding (i.e., frame rate decreases according to frame
timestamps) or when FramerateBitrateAdjuster was used.
Fixed this by using synthetic monotonically increasing timestamps
calculated based on target frame rate provided by bitrate adjuster.

This PR add support for the `PeerConnectionObserverJni::OnRemoveTrack()`
event on Java, allowing to be notified when a remote track has been
removed. It's a very thing JNI wrapper on top of C++ API, being mostly
similar to other already available events like `track` and `addTrack`.
In Javascript API, tracks are not "removed" explicitly from the
PeerConnection, but instead receiver PeerConnection gets notified that
they have been removed from the streams they are associated to, and when
no `MediaStream` object has that track, it's considered that the track
has been removed from the PeerConnection. In Java and C++ APIs there's no
`MediaStreamObserver` class, so there's no way to listen to the
`removeTrack` event the same way happens in Javascript API, but instead
C++ API has a `removeTrack` event at PeerConnection level. This patchset
just only wraps and expose this `removeTrack` event from the C++ API to
the Java API.
