I was notified by Randy Stewart that lksctp claims to be
"the reference implementation". First of all, "the
refrence implementation" was the original implementation
of SCTP in usersapce written ty Randy and a few others.
Second, after looking at the definiton of 'reference implementation',
we don't really meet the requirements.

When we recieve a FWD-TSN (meaning the peer has abandoned the data),
we need to clean up any partially received messages that may be
hanging out on the re-assembly or re-ordering queues. This is
a MUST requirement that was not properly done before.

This option was introduced in draft-ietf-tsvwg-sctpsocket-13. It
prevents head-of-line blocking in the case of one-to-many endpoint.
Applications enabling this option really must enable SCTP_SNDRCV event
so that they would know where the data belongs. Based on an
earlier patch by Ivan Skytte Jørgensen.
Additionally, this functionality now permits multiple associations
on the same endpoint to enter Partial Delivery. Applications should
be extra careful, when using this functionality, to track EOR indicators.

During association restart we may have stale data sitting
on the ULP queue waiting for ordering or reassembly. This
data may cause severe problems if not cleaned up. In particular
stale data pending ordering may cause problems with receive
window exhaustion if our peer has decided to restart the
association.

- added typedef unsigned int __nocast gfp_t;
- replaced __nocast uses for gfp flags with gfp_t - it gives exactly
the same warnings as far as sparse is concerned, doesn't change
generated code (from gcc point of view we replaced unsigned int with
typedef) and documents what's going on far better.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
