Provide a way to ask for an opaque version string for a locale_t, so
that potential changes in sort order can be detected. Similar to
ICU's ucol_getVersion() and Windows' GetNLSVersionEx(), this API is
intended to allow databases to detect when text order-based indexes
might need to be rebuilt.
The CLDR version is extracted from CLDR source data by the Makefile
under tools/tools/locale, written into the machine-generated Makefile
under shared/colldef, passed to localedef -V, and then written into
LC_COLLATE file headers. The initial version is 34.0.
tools/tools/locale was recently updated to pull down 35.0, but the
output hasn't been committed under share/colldef yet, so that will
provide the first observable change when it happens. Other versioning
schemes are possible in future, because the format is unspecified.

newlocale() optionally takes a "base" locale, from which components not
specified in the mask are inherited. POSIX says that newlocale() may
modify "base" and return it, or free "base" and return a newly allocated
locale. We were not doing either, so applications which use newlocale()
to modify an existing base locale end up leaking memory on FreeBSD.
This diff fixes the leak by releasing a reference to the base locale
before returning. This is less efficient than modifying "base"
directly, but is simpler for an initial bug fix. Also, update the man
page to clarify behaviour with respect to "base".

In a single-threaded program pthread_getspecific() always returns NULL,
so the old locale would not end up being freed.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.
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.
Our version of this function currently returns an integer indicating
failure or success, whereas POSIX specifies that this function has no
return value. It returns void. Patch up the header, sources and man page
to use the right type. While there, use the opportunity to simplify the
body of this function.
Theoretically speaking, this change breaks the ABI of this function.
That said, I have yet to find any code that makes use of freelocale()'s
return value. I couldn't find any of it in the base system, nor did an
exp-run reveal any breakage caused by this change.

- Address performance regressions encountered by das@ by caching per-thread
data in TLS where available.
- Add a __NO_TLS flag to cdefs.h to indicate where not available.
- Reorganise the xlocale.h definitions into xlocale/*.h so that they can be
included from multiple places.
- Export the POSIX2008 subset of xlocale when POSIX2008 says it should be
exported, independently of whether xlocale.h is included.
- Fix the bug where programs using ctype functions always assumed ASCII unless
recompiled.
- Fix some style(9) violations.

load of _l suffixed versions of various standard library functions that use
the global locale, making them take an explicit locale parameter. Also
adds support for per-thread locales. This work was funded by the FreeBSD
Foundation.
Please test any code you have that uses the C standard locale functions!
