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.

Note this is in the same time back out of our v1.3

Fix the style of the SCM ID's.
I believe have made all of libc .c's as consistent as possible.

If the string specifying the allowed options starts with a leading `:',
`getopt(3)' should not print a warning for missing argument values.

Don't print an error message if the bad option is '?'. This has been
in my tree for a long time. bde reviewed this once upon a time and
said it was OK, iirc. This also obviates the need to put ? in the
optstring argument to preclude the extra warning message which some
people think confuses users. When I made my getopt cleanups of a long
time ago, this was the compromise reached. I just neglected to commit
it until now.
