51369649b0 sys: 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.

fbbd9655e5 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.

76b96fbc9e Fix the checksum computation for UDPLite/IPv6. This requires the
usage of a function computing the checksum only over a part of the function.
Therefore introduce in6_cksum_partial() and implement in6_cksum() based
on that.
While there, ensure that the UDPLite packet contains at least enough bytes
to contain the header.

ecade87edf MFp4 bz_ipv6_fast:
Introduce a (for now copied stripped down) in6_cksum_pseudo()
  function.  We should be able to use this from in6_cksum() but
  we should also ponder possible MD specific improvements.
  It takes an extra csum argument to allow for easy checks as
  will be done by the upper layer protocol input paths.

2889eb8bdf MFp4 bz_ipv6_fast:
Optimize in6_cksum(), re-ordering work and limiting variable
  initialization, removing a bzero() for mostly re-initialized
  struct values, making use of the newly introduced in6_getscope(),
  as well as converting an if/panic to a KASSERT().

43bc7a9c62 With exception of the if_name() macro, all definitions in net_osdep.h
were unused or already in if_var.h so add if_name() to if_var.h and
remove net_osdep.h along with all references to it.

Longer term we may want to kill off if_name() entierly since all modern
BSDs have if_xname variables rendering it unnecessicary.

4e6098c6a4 We needn't check "m" for NULL here because "off" should be within
the mbuf chain.  If we ever get a buggy caller, a bogus "off" should
be caught by the sanity check at the function entry.  Null "m" here
means a very unusual condition of a totally broken mbuf chain (wrong
m_pkthdr.len or whatever), so we can just page fault later.

a1f7e5f8ee scope cleanup. with this change
- most of the kernel code will not care about the actual encoding of
  scope zone IDs and won't touch "s6_addr16[1]" directly.
- similarly, most of the kernel code will not care about link-local
  scoped addresses as a special case.
- scope boundary check will be stricter.  For example, the current
  *BSD code allows a packet with src=::1 and dst=(some global IPv6
  address) to be sent outside of the node, if the application do:
    s = socket(AF_INET6);
    bind(s, "::1");
    sendto(s, some_global_IPv6_addr);
  This is clearly wrong, since ::1 is only meaningful within a single
  node, but the current implementation of the *BSD kernel cannot
  reject this attempt.

3384154590 Sync with recent KAME.
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.
