feb1d5507e Add casts and L suffixes to libc quad support, to work around various
-Werror warnings from clang 10.0.0, such as:

Some of these routines exist in both lib/libc/quad/ and sys/libkern/.
r325988 ANSIfied sys/libkern.  Update libc/quad to match.

8a16b7a18f 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.

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.

I believe have made all of libc .c's as consistent as possible.
