General 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.

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.

libc/db/hash: cap auto-tuned block size with a value that actually works

This fix mostly matters after r206129 that made it possible for
st_blksize to be greater than 4K. For this reason, this change should
be MFC-ed before r206129.
Also, it seems that all FreeBSD uitlities that use db(3) hash databases
and create new databases in files, specify their own block size value
and thus do not depend on block size autotuning.
