include: 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 warnings about:

- an old-style function definition (with an empty parameter list)
- a variable that is possibly used uninitialized

"make tinderbox" passes this time, except for a few unrelated

Make use of clang nullability attributes.

Replace uses of the GCC __nonnull__ attribute with the clang nullability
qualifiers. The replacement should be transparent for clang developers as
the new qualifiers will produce the same warnings and will be useful for
static checkers but will not cause aggressive optimizations.

GCC will not produce such warnings and developers will have to use
upgraded GCC ports built with the system headers from r312538.

just enough of _WITH_GETLINE to allow these older source trees to

stdio.h: Fix function-type typedef style and use _types.h __ssize_t

I'm still not sure why only Pypy runs into the error with the function
typedefs. Fix it anyway.

Use __ssize_t instead of ssize_t for the types; it's possible for the size_t
type to not be visible if at the wrong POSIX_VISIBLE level.

A final (crossing my fingers) follow-up to r299456.
