Randall Stewart f42a358a6f - Copyright updates (aka 2007) 
- ZONE get now also take a type cast so it does the
  cast like mtod does.
- New macro SCTP_LIST_EMPTY, which in bsd is just
  LIST_EMPTY
- Removal of const in some of the static hmac functions
  (not needed)
- Store length changes to allow for new fields in auth
- Auth code updated to current draft (this should be the
  RFC version we think).
- use uint8_t instead of u_char in LOOPBACK address comparison
- Some u_int32_t converted to uint32_t (in crc code)
- A bug was found in the mib counts for ordered/unordered
  count, this was fixed (was referencing a freed mbuf).
- SCTP_ASOCLOG_OF_TSNS added (code will probably disappear
  after my testing completes. It allows us to keep a
  small log on each assoc of the last 40 TSN's in/out and
  stream assignment. It is NOT in options and so is only
  good for private builds.
- Some CMT changes in prep for Jana fixing his problem
  with reneging when CMT is enabled (Concurrent Multipath
  Transfer = CMT).
- Some missing mib stats added.
- Correction to number of open assoc's count in mib
- Correction to os_bsd.h to get right sha2 macros
- Add of special AUTH_04 flags so you can compile the code
  with the old format (in case the peer does not yet support
  the latest auth code).
- Nonce sum was incorrectly being set in when ecn_nonce was
  NOT on.
- LOR in listen with implicit bind found and fixed.
- Moved away from using mbuf's for socket options to using
  just data pointers. The mbufs were used to harmonize
  NetBSD code since both Net and Open used this method. We
  have decided to move away from that and more conform to
  FreeBSD style (which makes more sense).
- Very very nasty bug found in some of my "debug" code. The
  cookie_how collision case tracking had an endless loop in
  it if you got a second retransmission of a cookie collision
  case. This would lock up  a CPU .. ugly..
- auth function goes to using size_t instead of int which
  conforms to socketapi better
- Found the nasty bug that happens after 9 days of testing.. you
  get the data chunk, deliver it and due to the reference to a ch->
  that every now and then has been deleted (depending on the postion
  in the mbuf) you have an invalid ch->ch.flags.. and thus you don't
  advance the stream sequence number.. so you block the stream
  permanently. The fix is to make local variables of these guys
  and set them up before you have any chance of trimming the
  mbuf.
- style fix in sctp_util.h, not sure how this got bad maybe in
  the last patch? (aka it may not be in the real source).
- Found interesting bug when using the extended snd/rcv info where
  we would get an error on receiving with this. Thats because
  it was NOT padded to the same size as the snd_rcv info. We
  increase (add the pad) so the two structs are the same size
  in sctp_uio.h
- In sctp_usrreq.c one of the most common things we did for
  socket options was to cast the pointer and validate the size.
  This as been macro-ized to help make the code more readable.
- in sctputil.c two things, the socketapi class found a missing
  flag type (the next msg is a notification) and a missing
  scope recovery was also fixed.

* Routine Description:
*
* Computes the CRC32c checksum for the specified buffer using the slicing by 8
* algorithm over 64 bit quantities.
*
* Arguments:
*
* p_running_crc - pointer to the initial or final remainder value
* used in CRC computations. It should be set to
* non-NULL if the mode argument is equal to CONT or END
* p_buf - the packet buffer where crc computations are being performed
* length - the length of p_buf in bytes
* init_bytes - the number of initial bytes that need to be procesed before
* aligning p_buf to multiples of 4 bytes
* mode - can be any of the following: BEGIN, CONT, END, BODY, ALIGN
*
* Return value:
*
* The computed CRC32c value
