New port: net/sctplib

The SCTPLIB library is a prototype implementation of the Stream Control
Transmission Protocol (SCTP), a message-oriented reliable transport protocol
that supports multi-homing, and multiple message streams multiplexed within an
SCTP connection (also named association). SCTP is described in RFC 4960. See
https://www.uni-due.de/~be0001/sctplib/ for details. The API of the library is
modeled after Section 10 of RFC 4960, and most parameters and functions should
be self-explanatory to the user familiar with this document. In addition to
these interface functions between an Upper Layer Protocol (ULP) and an SCTP
instance, the library also provides a number of helper functions that can be
used to manage callbacks and timers, as well as UDP sockets for simple IPC.
Furthermore, SCTPLIB provides support for UDP encapsulation, making it possible
to co-exist with kernel SCTP implementations.
