The current send queue implements SCTP_SS_FCFS as defined in
https://datatracker.ietf.org/doc/html/rfc8260#section-3.1, but that has
always been known to be a temporary solution. The end goal is to
implement a Weighted Fair Queueing Scheduler (SCTP_SS_WFQ), but that's
likely to take some time.
Meanwhile, a round robin scheduler (SCTP_SS_RR) will be used to avoid
some issues with the current scheduler, such as a single data channel
completely blocking all others if it sends a lot of messages.
In this first commit, the code has simply been renamed and is still
implementing first-come-first-served. That will be fixed in follow-up
CLS.

This should avoid the situation where WebRTC's GN check is green and
Chromium (which turns it ON for //third_party/webrtc) fails.

This completes the basic implementation of the dcSCTP library. There
are a few remaining commits to e.g. add compatibility tests and
benchmarks, as well as more support for e.g. RFC8260, but those are not
strictly vital for evaluation of the library.
The Socket contains the connection establishment and teardown sequences
as well as the general chunk dispatcher.

This is merely a container of components that have their lifetime
bound to when the socket is connected. If the socket gets disconnected
or restarted, this object (and everything it holds) will be released.

The Stream Reset handler handles a limited subset of RFC6525, but all
the parts necessary to implement "Closing a Data Channel", which is done
by sending an Outgoing SSN Reset Request.
There can only be a single "Stream Reconfiguration Request" on the wire
at any time, so requests are queued and sent when a previous request -
if any - finishes. Resetting a stream is an asynchronous operation and
the receiver will not perform the stream resetting until it can be done,
which is when the currently partly received message has been fully
received. And the sender will not send a request until the currently
fragmented message (on that stream) is still sent.
There are numerous callbacks to make the client know what's really
happening as these callbacks will result in Data Channel events.

It's responsible for answering incoming Heartbeat Requests, and to
send requests itself when a connection is idle. When it receives
a response, it will measure the RTT and if it doesn't receive a response
in time, that will result in a TX error, which will eventually close
the connection.

In the Socket module, there are a few (two, to be exact right now, but
the goal is to have even more) separate "handlers" that are responsible
for a feature set. These handlers must have an API to interact with
the rest of the socket - and this is the API.
Mocks are also added.
