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.

The output file is created as a temporary file that is moved over the
existing file after completion. Thus there is no need to immediately
flush all created db records to the temporary file.
This speeds up creation of the termcap db by a factor of 40 on my
ZFS based /etc filesytem (from 25 seconds to 0.6 seconds).
I have compared multiple output files created with and without O_SYNC
and they came out identical each time. Nonetheless it might be best
to MFC this change and the similar one for services_mkdb (r295465) at
the same time when the changes to hash.c in review D5186 are merged.

Similar fix was done for passwd and group operations in r285050. When a
temporary file is created and then renamed to replace official file there
are no checks to make sure data was written to disk and if a power cycle
happens at this time, system can end up with a 0 length file

Also add $FreeBSD$ to a few files to keep svn happy.
Discussed with: imp, rwatson
which is stat.st_blksize (i.e., PAGE_SIZE).
This change causes the .db files that were cross-compiled on
another platform to be identical to the natively built ones.
Tested on: alpha->amd64 build
of the recent WARNS commits. The idea is:
1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.
