Add mkostempsat(3).

This is a variant of mkostemps() which takes a directory descriptor and
returns a descriptor for a tempfile relative to that directory. Unlike
the other mktemp functions, mkostempsat() can be used in capability

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.

Fix a few bugs with the _gettemp() routine which implements mkstemp(),
mkstemps(), and mkdtemp().
- Add proper range checking for the 'slen' parameter passed to mkstemps().
- Try all possible permutations of a template if a collision is encountered.
Previously, once a single template character reached 'z', it would not wrap
around to '0' and keep going until it encountered the original starting
letter. In the edge case that the randomly generated starting name used
all 'z' characters, only that single name would be tried before giving up.
