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

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.

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.

routed: Fix use after free.

For the multihomed case, ifp be used after being freed. NULL the value
after freeing it and avoid getting into the branch without reassigning
a new value.

routed(8): use NULL instead of zero for pointers.

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.

routed(8)/rtquery(8) bump/demote to WARNS=3 for all archs

- The MACHINE_ARCH check is not exhaustive (missing at least powerpc),
and generally not worth maintaining.
- While here, fix whitespace and ordering of the Makefile

Fix some wrong usages.

Fix casts which are not by definition safe, but which malloc(3)
makes safe for us.

Modernize prototypes (ie: no extern)

Make lots of stuff static.

Convert list of remote interfaces to LIST_* macros

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

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

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

Update routed to use the RFC 3678 protocol-independent multicast API. Use
IP_MULTICAST_IF with struct ip_mreqn (obtained from Linux) to tell the
stack which interface index to use for sending IPv4 datagrams.

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

Don't declare everything we find on a loopback interface for passive:

Only the actual loopback address should be declared passive, other
addresses are very likely to be desirable to announce.

Check for IFF_LOOPBACK instead of IFF_PASSIVE to determine if we have
an unknown interface type.

Replace ROUNDUP/ADVANCE with SA_SIZE

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.

Latest-and-greatest routed.
Includes RIPv2 and Router Discovery.

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.

Quoth Vern:

ftp.sgi.com:sgi/src/routed.tar.Z has a fix that has been cooking for a week
or so and that fixes a problem in the new hash tables for zillions of
interface aliases. The bug was that interfaces that come and go, such
as for SLIP and PPP, would get permanently lost.
