872b698bd4 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.

7e6cabd06e 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.

df2a89db2b - Add -W flag support for network column in intpr() (-i flag) and
routepr() (-r flag).  It is too narrow to show an IPv6 prefix
  in most cases.

- Accept "local" as a synonym of "unix" in protocol family name.

- Show a prefix length in CIDR notation when name resolution failed in
  netname().

- Make routename() and netname() AF-independent and remove
  unnecessary typecasting from struct sockaddr.

- Use getnameinfo(3) to format L2 addr in intpr().

- Fix a bug which showed "Address" when -A flag is specfied in pr_rthdr().

- Replace cryptic GETSA() macro with SA_SIZE().

- Fix declarations shadowing local variables with the same names.

- Add more static, remove unused header files and variables.

7d73ba1804 Add the ability to set `prefer_source' flag to an IPv6 address.
It affects the IPv6 source address selection algorithm (RFC 6724)
and allows override the last rule ("longest matching prefix") for
choosing among equivalent addresses. The address with `prefer_source'
will be preferred source address.

e7e5b53bf1 Replace index() and rindex() calls with strchr() and strrchr().
The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.

This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.

5d8f0a53a7 Remove the single global unlocked route cache ip6_forward_rt
from the inet6 stack along with statistics and make sure we
properly free the rt in all cases.

While the current situation is not better performance wise it
prevents panics seen more often these days.
After more inet6 and ipsec cleanup we should be able to improve
the situation again passing the rt to ip6_forward directly.

Leave the ip6_forward_rt entry in struct vinet6 but mark it
for removal.

27187e7f6b Restore netstat -M functionality for most statistics on core dumps. In
general, when support was added to netstat for fetching data using sysctl,
no provision was left for fetching equivalent data from a core dump, and
in fact, netstat would _always_ fetch data from the live kernel using
sysctl even when -M was specified resulting in the user believing they
were getting data from coredumps when they actually weren't.  Some specific
changes:
- Add a global 'live' variable that is true if netstat is running against
  the live kernel and false if -M has been specified.
- Stop abusing the sysctl flag in the protocol tables to hold the protocol
  number.  Instead, the protocol is now its own field in the tables, and
  it is passed as a separate parameter to the PCB and stat routines rather
  than overloading the KVM offset parameter.
- Don't run PCB or stats functions who don't have a namelist offset if we
  are being run against a crash dump (!live).
- For the inet and unix PCB routines, we generate the same buffer from KVM
  that the sysctl usually generates complete with the header and trailer.
- Don't run bpf stats for !live (before it would just silently always run
  live).
- kread() no longer trashes memory when opening the buffer if there is an
  error on open and the passed in buffer is smaller than _POSIX2_LINE_MAX.
- The multicast routing code doesn't fallback to kvm on live kernels if
  the sysctl fails.  Keeping this made the code rather hairy, and netstat
  is already tied to the kernel ABI anyway (even when using sysctl's since
  things like xinpcb contain an inpcb) so any kernels this is run against
  that have the multicast routing stuff should have the sysctls.
- Don't try to dig around in the kernel linker in the netgraph PCB routine
  for core dumps.

Other notes:
- sctp's PCB routine only works on live kernels, it looked rather
  complicated to generate all the same stuff via KVM.  Someone can always
  add it later if desired though.
- Fix the ipsec removal bug where N_xxx for IPSEC stats weren't renumbered.
- Use sysctlbyname() everywhere rather than hardcoded mib values.
