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.

Also add $FreeBSD$ to a few files to keep svn happy.
Discussed with: imp, rwatson
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
Do not exit with status 0 if mkdep(1) cannot create output,
e.g. if .depend is not writable or the FS is readonly mounted.
Store arguments as comments for debugging purpose.
correct for C sources that are compiled by cc, while cpp (/usr/bin/cpp)
is bogus since it invokes /usr/libexec/cpp with different flags.
1.1.5 uses plain cc. This should be equivalent after -M is added, but
cc -M foo.s is completely broken (it invokes the assembler) while
cc -E -M foo.s just does nothing instead of generating a foo.o: foo.s
dependency.
IF $MKDEP_CPP is set, use it as the cpp instead of cc -E. Assembler
sources that are preprocessed using cpp directly should be mkdep'ed
with MKDEP_CPP=cpp. Such sources shouldn't exist but we still have
lots. foo.S should be compiled by cc -traditional (cc will invoke the
preprocessor) and foo.s should be compiled by cc (cc won't invoke the
preprocessor).
