PeerConnection now has a new setting in RTCConfiguration to enable use of
datagram transport for data channels. There is also a corresponding field
trial, which has both a kill-switch and a way to change the default value.
PeerConnection's interaction with MediaTransport for data channels has been
refactored to work with DataChannelTransportInterface instead.
Adds a DataChannelState and OnStateChanged() to the DataChannelSink
callbacks. This allows PeerConnection to listen to the data channel's
state directly, instead of indirectly by monitoring media transport
state. This is necessary to enable use of non-media-transport (eg.
datagram transport) data channel transports.
For now, PeerConnection watches the state through MediaTransport as well.
This will persist until MediaTransport implements the new callback.
Datagram transport use is negotiated. As such, an offer that requests to use
datagram transport for data channels may be rejected by the answerer. If the
offer includes DTLS, the data channels will be negotiated as SCTP/DTLS data
channels with an extra x-opaque parameter for datagram transport. If the
opaque parameter is rejected (by an answerer without datagram support), the
offerer may fall back to SCTP.
If DTLS is not enabled, there is no viable fallback. In this case, the data
channels are negotiated as media transport data channels. If the receiver does
not understand the x-opaque line, it will reject these data channels, and the
offerer's data channels will be closed.

First, the existing configuration parameter (use_datagram_transport) is
now optional.
The new field trial has two flag values:
1. Whether to enable the datagram transport (enabled)
2. Whether to use the datagram transport by default (default_value)
The first is a kill-switch. It disables the datagram transport, even
for applications which inject a datagram transport factory and specify
use_datagram_transport = true. This allows applications which hard-code
a datagram transport to switch it off via field trials.
This flag defaults to true, to avoid breaking downstream projects which
already inject and configure a datagram transport. It may be changed to
false after updating downstream to set this field trial flag to true
when required.
The second provides a default value to be used in case the
aforementioned use_datagram_transport parameter is unset. Applications
which explicitly set use_datagram_transport will use that value.
Applications which do not explicitly specify whether or not to use the
datagram transport will use it (or not) according to the default_value
flag.
One goal of this flag is to simplify rollout in applications which
already set field trials based on configuration, but require code
changes for new RTCConfiguration parameters. A second goal is to
provide platforms with a knob to control whether datagram transport is
"opt-in" or "opt-out".
This flag defaults to false, to prevent downstream projects from
unintentionally enabling the datagram tranpsort.

Integration with datagram transport will come in next CLs.
NOTE that since we now have implemented negotiation for media transport, we can replace configuration flags with field trials, but it will be done later for both media and datagram transports.

This patch makes VideoBitrateAllocatorFactory injectable
by adding to PeerConnectionDependencies instead of allowing it to be
overridden using MediaEngine (on PeerConnectionFactory).
With this patch VideoBitrateAllocatorFactory is owned
by the PeerConnection.
