sockstat can "hang" on getpwuid() calls in situations when FreeBSD
is joined to a directory service (AD/LDAP etc) and the directory
service fail to answer in a timely manner when trying to resolve
numeric UIDs to user names.

Attach sockstat -j to the specified jail if the jail is in a new vnet.
Otherwise we do not see all sockets belonging to the jail.

Replace size_t members with ksize_t (uint64_t) and pointer members
(never used as pointers in userspace, but instead as unique
idenitifiers) with kvaddr_t (uint64_t). This makes the structs
identical between 32-bit and 64-bit ABIs.
On 64-bit bit systems, the ABI is maintained. On 32-bit systems,
this is an ABI breaking change. The ABI of most of these structs
was previously broken in r315662. This also imposes a small API
change on userspace consumers who must handle kernel pointers
becoming virtual addresses.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
No functional change intended.
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.

addresses have to be printed.
While there, document the -v option in the man page.

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.

* 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.

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

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.
