MFC r326276:

various: general adoption of SPDX licensing ID tags.

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.

Add META_MODE support.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to

Still need to add real targets under targets/ to build packages.

Convert usr.sbin to LIBADD
Reduce overlinking

Make SOCK_RAW sockets to be truly raw, not modifying received and sent
packets at all. Swapping byte order on SOCK_RAW was actually a bug, an
artifact from the BSD network stack, that used to convert a packet to
native byte order once it is received by kernel.

Other operating systems didn't follow this, and later other BSD
descendants fixed this, leaving us alone with the bug. Now it is
clear that we should fix the bug.

The last big commit: let usr.sbin/ use WARNS=6 by default.

Add AS lookup functionality. On each hop we query a whois server to
find the corresponding AS for that IP (-a switch).
We can also choose a different whois server with the -A switch. The
default is whois.radb.net.

NOIPSEC -> TRACEROUTE_NO_IPSEC

Update for traceroute 1.4a12

Add '+FreeBSD' to the version string, to reflect that this program
bears little relationship to the one from LBL with the same
name and version number.

Set BINOWN=root explicitly for setuid root binaries.

This is not "useless", as one may have non-default
setting for BINOWN in make.conf, and we still want
these to be installed setuid root in this case.

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

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

Grab traceroute out of src/contrib/traceroute

Change strcpy() to strncpy() in several places, and give gethostname()
the real buffer size. Note that the strncpy(domain, ...) doesn't need to
be a strncpy(), since it is copying from itself to itself, but belts
and suspenders don't hurt and this is not time-critical code.

Decode ICMP_UNREACH_FILTER_PROHIB responses as !F, from RFC1812.
Suggested by: Bill Fenner <fenner@parc.xerox.com>

Additionally, print unrecognised ICMP_UNREACH codes numerically. eg, code
15 would show up as !<15>.

Back out part of my previous commit. The bug was fixed over 12 months
ago in FreeBSD more cleanly.

Fixes from NetBSD:
- inet_ntoa() returns a pointer to a static buffer, dont use it twice
in the same printf().
- prevent the possibility of never timing out
- Report two more ICMP error types (prohibited nets etc)
And some (commented out) enhancements that I use, but some don't like.

Fix last commit (and PR bin/1489) by creating both sockets before
setuid().

Drop setuid ASAP, to minimize code executed as root.
