The new directive and role "iscman" allow to tag & reference man pages in
our source tree. Essentially it is just namespacing for ISC man pages,
but it comes with couple benefits.
Differences from .. _man_program label we formerly used:
- Does not expand :ref:`man_program` into full text of the page header.
- Generates index entry with category "manual page".
- Rendering style is closer to ubiquitous to the one produced
by ``named`` syntax.
Differences from Sphinx built-in :manpage: role:
- Supports all builders with support for cross-references.
- Generates internal links (unlike :manpage: which generates external
URLs).
- Checks that target exists withing our source tree.

After some back and forth, it was decidede to match the configuration
option with unbound ("so-reuseport"), PowerDNS ("reuseport") and/or
nginx ("reuseport").
(cherry picked from commit 7e71c4d0cc)
Previously, the option to enable kernel load balancing of the sockets
was always enabled when supported by the operating system (SO_REUSEPORT
on Linux and SO_REUSEPORT_LB on FreeBSD).
It was reported that in scenarios where the networking threads are also
responsible for processing long-running tasks (like RPZ processing, CATZ
processing or large zone transfers), this could lead to intermitten
brownouts for some clients, because the thread assigned by the operating
system might be busy. In such scenarious, the overall performance would
be better served by threads competing over the sockets because the idle
threads can pick up the incoming traffic.
Add new configuration option (`load-balance-sockets`) to allow enabling
or disabling the load balancing of the sockets.

Historically, the inline keyword was a strong suggestion to the compiler
that it should inline the function marked inline. As compilers became
better at optimising, this functionality has receded, and using inline
as a suggestion to inline a function is obsolete. The compiler will
happily ignore it and inline something else entirely if it finds that's
a better optimisation.
Therefore, remove all the occurences of the inline keyword with static
functions inside single compilation unit and leave the decision whether
to inline a function or not entirely on the compiler
NOTE: We keep the usage the inline keyword when the purpose is to change
the linkage behaviour.

Previously, the unreachable code paths would have to be tagged with:
INSIST(0);
ISC_UNREACHABLE();
There was also older parts of the code that used comment annotation:
/* NOTREACHED */
Unify the handling of unreachable code paths to just use:
UNREACHABLE();
The UNREACHABLE() macro now asserts when reached and also uses
__builtin_unreachable(); when such builtin is available in the compiler.
(cherry picked from commit 584f0d7a7e)
Gcc 7+ and Clang 10+ have implemented __attribute__((fallthrough)) which
is explicit version of the /* FALLTHROUGH */ comment we are currently
using.
Add and apply FALLTHROUGH macro that uses the attribute if available,
but does nothing on older compilers.
In one case (lib/dns/zone.c), using the macro revealed that we were
using the /* FALLTHROUGH */ comment in wrong place, remove that comment.

The named-checkzone(1) and named-compilezone(1) manual pages used to

Remove outdated command references from ARM section
3.3.1. Tools for Use With the Name Server Daemon
and replace them with links to man pages.
Fixes: #2799
(cherry picked from commit 2d2d87a615)
Both utilities were included as one man page, but this caused a problem:
Sphinx directive .. include was used twice on the same file, which
prevented us from using labels (or anything with unique identifier) in
the man pages. This effectivelly prevented linking to them.
Splitting man pages allows us to solve the linking problems and also
clearly make text easier to follow because it does not mention two tools
at the same time.
This change causes duplication of text, but given the frequecy of changes
to these tools I think it is acceptable. I've considered deduplication
using smaller .rst snippets which get included into both man pages,
but it would require more sed scripting to handle defaults etc. and
I think it would be way too complex solution for this problem.

Add a note to the DNSSEC guide and to the ARM reference that A ZSK/KSK
pair used for signing your zone should have the same algorithm.
This commit also updates the 'dnssec-policy/keys' example to use the
slightly more modern 'rsasha256' algorithm.

For users it's not really important if a RFC is Internet Standard,
Proposed Standard, or Experimental. RFCs are now regrouped by
"Protocol", Best Current Practice, and "catch all" category FYI.

In 2022, IPv6 is not anything unusual, and it was really odd
to have it in a separate section next to a huge list of RFCs.
Fixes: #1918
(cherry picked from commit 2774b497a6)
There is little point of listing all of the obsolete RFCs. I think it is
more likely confuse people than to do anything useful.
