In the example below, the association is being established between peer
A and Z, and A is the initiating party.
Before this CL, when an association was about to be established, Z would
after having received the INIT chunk, persist state in the socket about
which verification tag and initial TSN that was picked. These would be
re-generated on every incoming INIT (that's fine), but when A had
extracted the cookie from INIT_ACK and sent a reply (COOKIE_ECHO) with
the state cookie, that could fail validation when it's received by Z, if
the sent cookie was not the most recent one or if the COOKIE_ECHO had a
verification tag coming not from the most recent INIT_ACK, because Z had
replaced the state in the socket with the one generated when the second
INIT_ACK chunk was generated - state it used for validation of future
received data.
In other words:
A -> INIT 1
<timeout>
A -> INIT 2 (retransmission of INIT 1)
INIT 1 -> Z - sends INIT_ACK 1 with verification_tag=1, initial_tsn=1,
cookie 1 (and records these to socket state)
INIT 2 -> Z - sends INIT_ACK 2 with verification_tag=2, initial_tsn=2,
cookie 2 (replaces socket state with the new data)
INIT_ACK 1 -> A -> sends COOKIE_ECHO with verification_tag=1, cookie 1
COOKIE_ECHO (cookie 1) -> Z <FAILS, as the state isn't as expected>.
The solution is really to do what RFC4960 says, to not maintain any
state as the receiving peer until COOKIE_ECHO has been received. This
was initially not done because the underlying reason why this is
important in SCTP is to avoid denial of service, and this is why SCTP
has the four-way handshake. But for Data Channels - SCTP over DTLS -
this attack vector isn't available. So the implementation was
"simplified" by keeping socket state instead of encoding it in the
state cookie, but that obviously had downsides.
So with this CL, the non-initiating peer in connection establishment
doesn't keep any socket state, and puts all that state in the state
cookie instead. This allows any COOKIE_ECHO to be received by Z.

This is the first step, which introduces the new name and prefers it if
it is set, but keeps the old name for backwards compat reasons.
Once Chromium has migrated to the new name, we can delete the old name.

This is a replacement for `connections()`, which is const-qualified but
returns a `rtc::ArrayView<const cricket::Connection*>`. Unfortunately,
this is a view of mutable pointers to `const cricket::Connection`
objects: this means that the pointers in `IceControllerInterface`'s
backing store can be reassigned.
Returning `rtc::ArrayView<const cricket::Connection* const>` is more
consistent with how a view returned from a const-qualified method should
behave. Unfortunately, there are downstream overrides of this method, so
instead of just fixing this outright, add a new method with the correct
return type. Once downstream is updated, the old method can then be
removed.

And the same for outstanding items, which become unacked items. The old
names were unfortunate - especially since they were managed by a class
called OutstandingData.
To make this less complicated, these variables have been renamed to
something that is easier to understand; "Unacked bytes/items". Simply
what has been sent but hasn't been acked or nacked yet. So likely what's
in-flight, but could possibly be lost and not found to be lost yet.

A std::map is a fairly inefficient data structure. Accessing an item
is O(log(N)), but as every item is a separate allocation, iterating it
and searching for items is not very kind to the data caches.
As the outstanding data is a contiguous list (no gaps) where you only
append to the end and remove from the front, use a std::deque instead.

This change ensures that the FCA now is informed about a new max fps
when VideoStreamEncoder::OnVideoSourceRestrictionsUpdated is called.
The latest restricted frame rate which is provided to the FCA will
only affect the cadence of repeated non-idle (quality has not
converged) frames and the main goal is to ensure that the FCA reduces
its repeat rate in situations where the video source is constrained.
UpdateVideoSourceRestrictions is added to the FrameCadenceAdapter API
and it is called from the VideoStreamEncoder when its source
parameters (resolution and/or frame rate) are restricted.
This modification has no effect on the flow driven by
ProcessOnDelayedCadence (non repeated frames).
