arpa: garbage collect ns_newmsg/ns_rdata decls

These were brought in by the libbind import, but these functions were
never actually implemented anywhere, only header declarations and symbol
map entries were imported.

SPDX: license IDs for some ISC-related files.

include: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

include: minor spelling fixes.

No functional change.

Bring final version of libbind:

From
http://www.isc.org/downloads/libbind/

The libbind functions have been separated from the BIND suite as of BIND
9.6.0. Originally from older versions of BIND, they have been continually
maintained and improved but not installed by default with BIND 9. This
standard resolver library contains the same historical functions and
headers included with many Unix operating systems. In fact, most
implementations are based on the same original code.

At present, NetBSD maintains libbind code, now known as "netresolv".

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Remove clause 3 from Berkeley copyrights. Add a few $FreeBSD$'s.

Merge the resolver part of BIND 9.4.3 into HEAD.
It includes the following fix:

2426. [bug] libbind: inet_net_pton() can sometimes return the
wrong value if excessively large netmasks are
supplied. [RT #18512]

Reported by: Maksymilian Arciemowicz <cxib__at__securityreason.com>

Import the resolver part of BIND 9.4.3.

- Import the HEAD csup code which is the basis for the cvsmode work.

Merge BIND 9.4.1 into main chunk.

MFC after: 2 weeks

Vendor import of BIND 9.4.1

Upgrade res_update(3) and the friends to BIND9's one excluding TSIG
support.

X-MFC after: never

Update the resolver in libc to BIND9's one.

Since, res_sendsigned(3) and the friends use MD5 functions, it is
hard to include them without having MD5 functions in libc. So,
res_sendsigned(3) is not merged into libc.

Since, res_update(3) in BIND9 is not binary compatible with our
res_update(3), res_update(3) is leaved as is, except some
necessary modifications.
The res_update(3) and the friends are not essential part of the
resolver. They are not defined in resolv.h but defined in
res_update.h separately in BIND9. Further, they are not called from
our tree. So, I hide them from our resolv.h, but leave them only
for binary backward compatibility (perhaps, no one calls them).

Since, struct __res_state_ext is not exposed in BIND9, I hide it
from our resolv.h. And, global variable _res_ext is removed. It
breaks binary backward compatibility. But, since it is not used from
outside of our libc, I think it is safe.

Vendor import of BIND 9.3.2

ns_name_skip was not prefixed by `__'.

Obtained from: BIND9

Breath deep and take __P out of the system include files.

# This appears to not break X11, but I'm having problems compiling the
# glide part of the server with or without this patch, so I can't tell
# for sure.

Implement EDNS0 support, as EDNS0 support will be made mandatory for
IPv6 transport-ready resolvers/DNS servers. Need careful configuration
when enable it. (default config is not affected).
See manpage for details.

XXX visible symbol __res_opt() is added, however, it is not supposed to be
called from outside, libc minor is not bumped.

$Id$ -> $FreeBSD$

Change an internal variable from "class" to "ns_class" for C++'s benefit.
Apparently BIND-8.2.1 uses ns_class.

Submitted by: John Plevyak <jplevyak@inktomi.com>

Update nameserver interface to bind-8.1.2 levels. We do not use IRS (yet?)
since it has far wider impact than hostname lookups (including passwords).
Note that this has more ugly symbol hiding and binary compatability hacks
that can go away the second we bump majors.

Obtained from: Mostly from diff against ISC bind-8.1.2 sources

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Update 4.9.4-P1 -> 4.9.5-P1
Included here are definitions for the DNSSEC key management stuff.

Hand merge in the bind-4.9.4-P1 resolver updates.

Fix a bunch of spelling errors in the comment fields
of a bunch of system include files.

Update resolver include files to bind-4.9.3-rel level

Update the resolver include files to bind-4.9.3-beta24 level (from beta9p1)
Note: this was done by selective patching from diffs by hand, in order
to not conflict with the 4.4BSD base code. Beta9 was done the same way.

Remove trailing whitespace.
