sbin/routed: Remove unused code for sgi and NetBSD.

MFC after: 2 weeks

General 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.

Fix userland tools that don't check the format of routing socket
messages before accessing message fields that may not be present,
removing dead/duplicate/misleading code along the way.

Document the message format for each routing socket message in
route.h.

Fix a bug in usr.bin/netstat introduced in r287351 that resulted in
pointer computation with essentially random 16-bit offsets and
dereferencing of the results.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

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.

Add some consts, remove some unused stuff and other attempts to calm
FlexeLint down.

Modernize prototypes (ie: no extern)

Make lots of stuff static.

Kick WARNS level up to 6 by fixing various trivial warnings.

Use <sys/queue.h> to manage the interface list.

This main goals of this project are:
1. separating L2 tables (ARP, NDP) from the L3 routing tables
2. removing as much locking dependencies among these layers as
possible to allow for some parallelism in the search operations
3. simplify the logic in the routing code,

The most notable end result is the obsolescent of the route
cloning (RTF_CLONING) concept, which translated into code reduction
in both IPv4 ARP and IPv6 NDP related modules, and size reduction in
struct rtentry{}. The change in design obsoletes the semantics of
RTF_CLONING, RTF_WASCLONE and RTF_LLINFO routing flags. The userland
applications such as "arp" and "ndp" have been modified to reflect
those changes. The output from "netstat -r" shows only the routing
entries.

Quite a few developers have contributed to this project in the
past: Glebius Smirnoff, Luigi Rizzo, Alessandro Cerri, and
Andre Oppermann. And most recently:

- Kip Macy revised the locking code completely, thus completing
the last piece of the puzzle, Kip has also been conducting
active functional testing
- Sam Leffler has helped me improving/refactoring the code, and
provided valuable reviews
- Julian Elischer setup the perforce tree for me and has helped
me maintaining that branch before the svn conversion

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

Remove #ident directives, they don't exist on the vendor branch anymore.

Ignore kernel routes with the RTF_WASCLONED flag set. This is a slight
modification of a patch which was already applied for BSD/OS in the
Rhyolite.com sources; this file is already off the vendor branch.

Virgin import of rhyolite.com routed v2.27

Correct typos, mostly s/ a / an / where appropriate. Some whitespace cleanup,
especially in troff files.

o Move NTOHL() and associated macros into <sys/param.h>. These are
deprecated in favor of the POSIX-defined lowercase variants.
o Change all occurrences of NTOHL() and associated marcros in the
source tree to use the lowercase function variants.
o Add missing license bits to sparc64's <machine/endian.h>.
Approved by: jake
o Clean up <machine/endian.h> files.
o Remove unused __uint16_swap_uint32() from i386's <machine/endian.h>.
o Remove prototypes for non-existent bswapXX() functions.
o Include <machine/endian.h> in <arpa/inet.h> to define the
POSIX-required ntohl() family of functions.
o Do similar things to expose the ntohl() family in libstand, <netinet/in.h>,
and <sys/param.h>.
o Prepend underscores to the ntohl() family to help deal with
complexities associated with having MD (asm and inline) versions, and
having to prevent exposure of these functions in other headers that
happen to make use of endian-specific defines.
o Create weak aliases to the canonical function name to help deal with
third-party software forgetting to include an appropriate header.
o Remove some now unneeded pollution from <sys/types.h>.
o Add missing <arpa/inet.h> includes in userland.

Spelling, add rcsid, remove unused #includes.
Convert 1000000 usec to 1 sec 0 usec.
Use provided safe malloc (rtmalloc()) instead of malloc(): exit on allocation
failure.
Correct use of .Nm
Add usage() and use errx().

Check if routed had the same problems that route(1) had.
The answer is not really, but almost.
it sent data that was ok, though it was a hack,
but it was bug-compatible with the kernel on receiving them. This also
had been fixed with a hack.. I hacked it better I think.
