This one will implement all the interface of inet_diag, inet_diag_handler.
which includes sctp_diag_dump, sctp_diag_dump_one and sctp_diag_get_info.
It will work as a module, and register inet_diag_handler when loading.
v2->v3:
- fix the mistake in inet_assoc_attr_size().
- change inet_diag_msg_laddrs_fill() name to inet_diag_msg_sctpladdrs_fill.
- change inet_diag_msg_paddrs_fill() name to inet_diag_msg_sctpaddrs_fill.
- add inet_diag_msg_sctpinfo_fill() to make asoc/ep fill code clearer.
- add inet_diag_msg_sctpasoc_fill() to make asoc fill code clearer.
- merge inet_asoc_diag_fill() and inet_ep_diag_fill() to
inet_sctp_diag_fill().
- call sctp_diag_get_info() directly, instead by handler, cause the caller
is in the same file with it.
- call lock_sock in sctp_tsp_dump_one() to make sure we call get sctp info
safely.
- after lock_sock(sk), we should check sk != assoc->base.sk.
- change mem[SK_MEMINFO_WMEM_ALLOC] to asoc->sndbuf_used for asoc dump when
asoc->ep->sndbuf_policy is set. don't use INET_DIAG_MEMINFO attr any more.

sctp_init_cmd_seq() and sctp_next_cmd() are only called from one place.
The call sequence for sctp_add_cmd_sf() is likely to be longer than
the inlined code.
With sctp_add_cmd_sf() inlined the compiler can optimise repeated calls.

This patch implement sctp association probing module, the module
will be called sctp_probe.
This module allows for capturing the changes to SCTP association
state in response to incoming packets. It is used for debugging
SCTP congestion control algorithms.
Usage:
$ modprobe sctp_probe [full=n] [port=n] [bufsize=n]
$ cat /proc/net/sctpprobe
The output format is:
TIME ASSOC LPORT RPORT MTU RWND UNACK <REMOTE-ADDR STATE CWND SSTHRESH INFLIGHT PARTIAL_BYTES_ACKED MTU> ...
The output will be like this:

This puts CONFIG_PROC_FS defines around the proc init/exit functions
and also avoids compiling proc.c if procfs is not supported.
Also make SCTP_DBG_OBJCNT depend on procfs.

The crc32c library used an identical table and algorithm
as SCTP. Switch to using the library instead of carrying
our own table. Using crypto layer proved to have too
much overhead compared to using the library directly.

This patch implements the internals operations of the AUTH, such as
key computation and storage. It also adds necessary variables to
the SCTP data structures.

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!
