This handles a corner case whereby an OnStateChange implementation
synchronously calls UnregisterObserver, which would (before this CL)
delete the observer adapter.

This updates sctp channels, including work that happens between the
data channel controller and the transport, to run on the network
thread. Previously all network traffic related to data channels was
routed through the signaling thread before going to either the network
thread or the caller's thread (e.g. js thread in chrome). Now the
calls can go straight from the network thread to the JS thread with
enabling a special flag on the observer (see below) and similarly
calls to send data, involve 2 threads instead of 3.
* Custom data channel observer adapter implementation that
maintains compatibility with existing observer implementations in
that notifications are delivered on the signaling thread.
The adapter can be explicitly disabled for implementations that
want to optimize the callback path and promise to not block the
network thread.
* Remove the signaling thread copy of data channels in the controller.
* Remove several PostTask operations that were needed to keep things
in sync (but the need has gone away).
* Update tests for the controller to consistently call
TeardownDataChannelTransport_n to match with production.
* Update stats collectors (current and legacy) to fetch the data
channel stats on the network thread where they're maintained.
* Remove the AsyncChannelCloseTeardown test since the async teardown
step has gone away.
* Remove `sid_s` in the channel code since we only need the network
state now.
* For the custom observer support (with and without data adapter) and
maintain compatibility with existing implementations, added a new
proxy macro that allows an implementation to selectively provide
its own implementation without being proxied. This is used for
registering/unregistering a data channel observer.
* Update the data channel proxy to map most methods to the network
thread, avoiding the interim jump to the signaling thread.
* Update a plethora of thread checkers from signaling to network.

The FakePeriodicVideoSource was not actually stopping its repeated
handle, which takes a raw pointer to the task queue. There could be a
race here where a repeated task was being posted at the same time as
the task queue was being destroyed due to the scoped safety flag being
tied to the repeated task rather than the task queue.
I'm still unable to repro locally, so this is a speculative fix.

This updates DataChannelControllerTests to shut down the DCC in the
same way it's shut down by the owning PeerConnection instance:
* Call TeardownDataChannelTransport_n()
* Call PrepareForShutdown()
Also calling PrepareForShutdown() from PC's dtor to be consistent with
how `sdp_handler_->PrepareForShutdown()` is called since it appears
that many tests do not call PC::Close() before destruction.

Only in testing environments are the task queues shut down while sources
still have media flowing. It's still not clear why heap-use-after-free
happens, since it should be enough to close the PC, but it is clear that
the crash is happening due to frames flowing while the test is shutting
down, which is not something happening outside of testing.
In an attempt to deflake, this CL makes sure to manually stop the
test-only sources before closing the peer connection.

If configured, the packet parser will allow packets with
a set checksum of zero. In that case, the correct checksum
will not even be calculated, avoiding a CPU intensive
calculation.
Also, if specified when building a packet, the checksum can
be opted to be not calculated and written to the packet.
This is to be used when draft-tuexen-tsvwg-sctp-zero-checksum
has been negotiated, except for some packets during association
establishment.
This is mainly a preparation CL and follow-up CL will enable
this feature.

The goal is to reduce the amount of time stretching done in response
to network jitter. Specifically, we should be able to “ride” over delay
spikes if the current delay is sufficient, without decelerating
playout. We should also avoid accelerating immediately after a buffer
underrun, until we are reasonably sure that the jitter has passed.
This is achieved by increasing the deadband where we choose to do
normal playout, based on the maximum delay in the short term packet
arrival history.
The buffer level filter is still used to report the average delay for
A/V sync purposes.
The new behavior is behind a flag and will be experimented with before
it is made default.

The tests now have two ways of addressing the channel under test:
* channel_: All SctpDataChannelTest methods. This way calls get
executed as specified by the proxy and more accurately reflects
production.
* inner_channel: For SctpDataChannel methods that are not a part of
the SctpDataChannelTest interface. Use this to invoke event handlers
etc.
Upcoming changes will include threading changes and changes to the
proxy, so it's important to cover both.
