Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

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.
Initially, only tag files that use BSD 4-Clause "Original" license.

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.

contain kernel pointers, and instead has interface index.
Bump __FreeBSD_version for that change.
o Now, netstat/mroute6.c no longer needs to kvm_read(3) struct ifnet, and
no longer needs to include if_var.h
Note that this change is far from being a complete move of IPv6 multicast
routing to a proper API. Other structures are still dumped into their
sysctls as is, requiring userland application to #define _KERNEL when
including ip6_mroute.h and then call kvm_read(3) to gather all bits and
pieces. But fixing this is out of scope of the opaque ifnet project.

necessary symbols needed per subsystem. Main kvm(3) init is now delayed
as much as possbile. This finally fixes performance issues reported in
kern/167204.
Some non-working code (ng_socket.ko symbol addresses calculation) removed.
Some global variables eliminated.

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.

Change wording of comments to reflect the fact we should unconditionally
use KVM if the -M option is used to specify a core file.
Add comments to document the fact that IPv6 multicast forwarding
information display still relies on KVM for gathering information.

extensions in both the C language and the bitwidth of kernel counters.

1) Include arpa/inet.h for ntohs.
2) Constness fixes.
3) Fix shadowing except for "sin" which shouldn't be in scope.
4) Remove register keyword.
5) Add missing initialsers to user defined structs.
5) Make prototype of netname6 globally visable.
6) Use right macros for printing syncache stats (even though entrie isn't
a word).
The compatibility glue is still provided.
(This change is not yet reflected in the manpage, nor
in usage(). This will be fixed at a later time today,
with the general manpage cleanup commit.)
This work was based on kame-20010528-freebsd43-snap.tgz and some
critical problem after the snap was out were fixed.
There are many many changes since last KAME merge.
TODO:
- The definitions of SADB_* in sys/net/pfkeyv2.h are still different
from RFC2407/IANA assignment because of binary compatibility
issue. It should be fixed under 5-CURRENT.
- ip6po_m member of struct ip6_pktopts is no longer used. But, it
is still there because of binary compatibility issue. It should
be removed under 5-CURRENT.
