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 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.

Unfortunately filemon/meta mode tracks all indirect dependencies here
since ld(1) is reading libelf when linking in libkvm. Churn would be
reduced if this was able to be limited to direct dependencies.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

code can read the buffer via sysctl or from a core file. In the core file
case there will be no nulterm, and the code copes with that, but now in the
sysctl case there is a nulterm (there didn't used to be). The least
disruptive way to restore the old behavior (and eliminate a spurious '\000'
at the end of the output) is to remove the nulterm (by decrementing the
buffer length) in the sysctl case.
- When operating on a core file (-M) and -c is specified we don't clear
the message buffer of the running system.
- If we don't have permission to clear the buffer print the error message
only. That's what Linux does in this case, where this feature was ported
from, and it ensures that the error message doesn't get lost in the noise.

of <%d> lines more strict.
Also simplify the logic a little:
- Start off by making the buffer linear so that we don't have to
deal with it wrapping around (suggested by bde).
- Process line by line rather than byte at a time.
with a new implementation that has a mostly reentrant "addchar"
routine, supports multiple message buffers in the kernel, and hides
the implementation details from callers.
The new code uses a kind of sequence number to represend the current
read and write positions in the buffer. This approach (suggested
mainly by bde) permits the read and write pointers to be maintained
separately, which reduces the number of atomic operations that are
required. The "mostly reentrant" above refers to the way that while
it is now always safe to have any number of concurrent writers,
readers could see the message buffer after a writer has advanced
the pointers but before it has witten the new character.
