0e229f343f Hide struct socket and struct unpcb from the userland.
Violators may define _WANT_SOCKET and _WANT_UNPCB respectively and
are not guaranteed for stability of the structures.  The violators
list is the the usual one: libprocstat(3) and netstat(1) internally
and lsof in ports.

In struct xunpcb remove the inclusion of kernel structure and add
a bunch of spare fields.  The xsocket already has socket not included,
but add there spares as well.  Embed xsockbuf into xsocket.

Sort declarations in sys/socketvar.h to separate kernel only from
userland available ones.

cc65eb4e79 Hide struct inpcb, struct tcpcb from the userland.
This is a painful change, but it is needed.  On the one hand, we avoid
modifying them, and this slows down some ideas, on the other hand we still
eventually modify them and tools like netstat(1) never work on next version of
FreeBSD.  We maintain a ton of spares in them, and we already got some ifdef
hell at the end of tcpcb.

Details:
- Hide struct inpcb, struct tcpcb under _KERNEL || _WANT_FOO.
- Make struct xinpcb, struct xtcpcb pure API structures, not including
  kernel structures inpcb and tcpcb inside.  Export into these structures
  the fields from inpcb and tcpcb that are known to be used, and put there
  a ton of spare space.
- Make kernel and userland utilities compilable after these changes.
- Bump __FreeBSD_version.

edc9c7fc7c This patch fixes two bugs:
* sctp46, tcp46, and udp46 sockets are displayed as such and not as
  sctp4 6, tcp4 6, udp4 6. This bug was introduced in
  http://svnweb.freebsd.org/base?view=revision&revision=187915
* For SCTP sockets, the the -4 and -6 flags are honoured as much as
  possible. This means IPv4 sockets are handled correctly,  IPv6
  sockets are displayed as sctp46, since it is currently not possible
  to distinguish between sctp6 and sctp46.

f03482d48e When using -L the code skips a socket if the local or foreign
address is loopback. So it is shown if both are not loopback.
The man page says that it is shown if the local or foreign
address is not loopback. Change the man page to reflect the
code.

09fe63205c - Updated TOE support in the kernel.
- Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs.
  These are available as t3_tom and t4_tom modules that augment cxgb(4)
  and cxgbe(4) respectively.  The cxgb/cxgbe drivers continue to work as
  usual with or without these extra features.

- iWARP driver for Terminator 3 ASIC (kernel verbs).  T4 iWARP in the
  works and will follow soon.

Build-tested with make universe.

30s overview
============
What interfaces support TCP offload?  Look for TOE4 and/or TOE6 in the
capabilities of an interface:
# ifconfig -m | grep TOE

Enable/disable TCP offload on an interface (just like any other ifnet
capability):
# ifconfig cxgbe0 toe
# ifconfig cxgbe0 -toe

Which connections are offloaded?  Look for toe4 and/or toe6 in the
output of netstat and sockstat:
# netstat -np tcp | grep toe
# sockstat -46c | grep toe

003e7e4928 Try to avoid ambiguity when sysctl returns ENOMEM additionally
checking the returned oldlen: when ENOMEM is due to the supplied
buffer being too short the return oldlen is equal to buffer size.

Without this additional check sockstat gets stuck in loop leaking the
memory if the returned ENOMEM was due the exceeded memorylocked
limit. This is easily can be observed running `limits -l 1k sockstat'.
