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.

Make stdio deferred cancel-safe.

If used with fopen(3)/fdopen(3)-ed FILEs, stdio accurately uses
non-cancellable internal versions of the functions, i.e. it seems to
be fine with regard to cancellation. But if the funopen(3) and
f{r,w}open(3) functions were used to open the FILE, and corresponding
user functions create cancellation points (they typically have no
other choice), then stdio code at least leaks FILE' lock.

The change installs cleanup handler which unlocks FILE. Some minimal
restructuring of the code was required to make it use common return
place to satisfy hand-rolled pthread_cleanup_pop() requirements.

fputs: Return the number of bytes written.

POSIX.1-2008 requires that successful completion simply return a
non-negative integer. We have regularly returned a constant value.
Another, equally valid, implementation convention implies returning
the number of bytes written.

Adopt this last convention to be in line with what Apple's libc
does. POSIX also explicitly notes:

Note that this implementation convention cannot be adhered to for strings
longer than {INT_MAX} bytes as the value would not be representable in the
return type of the function. For backwards-compatibility, implementations
can return the number of bytes for strings of up to {INT_MAX} bytes, and
return {INT_MAX} for all longer strings.

Developers shouldn't depend specifically on either convention but
the change may help port software from Apple.
