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.

Remove broken support for collation in [a-z] type ranges.
Only first 256 wide chars are considered currently, all other are just
dropped from the range. Proper implementation require reverse tables
database lookup, since objects are really big as max UTF-8 (1114112
code points), so just the same scanning as it was for 256 chars will
slow things down.

POSIX does not require collation for [a-z] type ranges and does not
prohibit it for non-POSIX locales. POSIX require collation for ranges
only for POSIX (or C) locale which is equal to ASCII and binary for
other chars, so we already have it.

No other *BSD implements collation for [a-z] type ranges.

Restore ABI compatibility with unused now __collate_range_cmp() which
is visible from outside (will be removed later).

Remove incorrect __restrict qualifier on several pointers

The typical case was:
static __inline int
convert_ccl(FILE *fp, char * __restrict p, [...])
{
[...]

if (p == SUPPRESS_PTR) {
[...]
} else {
[...]
}

[...]
}

This qualifier says that the pointer is the only one at that time
pointing to the resource.

Here, clang considers that "p" will never match "SUPPRESS_PTR" and
optimize the if{} block out. This leads to segfaults in programs calling
vfscanf(3) and vfwscanf(3) with just the format string (no arguments
following it).

The following softwares were reported to abort with segmentation fault
and this patch fixes it:
o cmake
o smartd
o devel/ORBit2

Previously, vfscanf()'s wide character processing functions were
reading wide characters manually. With this change, they now use
fgetwc(). To make this work, we use an internal version of fgetwc()
with a few extensions: it takes an mbstate * because non-wide streams
don't have a built-in mbstate, and it indicates the number of bytes
read.

vfscanf() now resembles vfwscanf() more closely. Minor functional
improvements include working xlocale support in vfscanf(), setting the
stream error indicator on encoding errors, and proper handling of
shift-based encodings. (Actually, making shift-based encodings work
with non-wide streams is hopeless, but the implementation now matches
the broken specification.)
