dcsctp: Add strong typed identifiers

There are numerous identifiers and sequences in SCTP, all of them being
unsigned 16 or 32-bit integers.

  * Stream identifiers
  * Payload Protocol Identifier (PPID)
  * Stream Sequence Numbers (SSN)
  * Message Identifiers (MID)
  * Fragment Sequence Numbers (FSN)
  * Transmission Sequence Numbers (TSN)

The first two of these are publicly exposed in the API, and the
remaining ones are never exposed to the client and are all part of SCTP
protocol.

Then there are some more not as common sequence numbers, and some
booleans. Not all will be in internal_types.h - it depends on if they
can be scoped to a specific component instead. And not all types will
likely become strong types.

The unwrapped sequence numbers have been renamed to not cause conflicts
and the current UnwrappedSequenceNumber class doesn't support wrapping
strongly typed integers as it can't reach into the type of the
underlying integer. That's something to explore later.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
