libc: further adoption of SPDX licensing ID tags.

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.

Implement xlocale APIs from Darwin, mainly for use by libc++. This adds a
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!

Fix PR

Empty string test gone wrong.

Testing this requires that you have a locale that has the sign string
unset but has int_n_sign_posn set (the default locale falls through to
use "()" around negative numbers which is probably another bug).

I created that setup by hand and indeed without this fix negative
numbers are put out as positive numbers (doesn't fall through to use
"-" as default indicator).

Unfixed example in nl_NL.ISO8859-1 with lc->negative_sign set to empty
string:
strfmon(buf, sizeof(buf), "%-8i", -42.0);
==>
example2: 'EUR 42,00' 'Eu 42,00'

Fixed:
example2: 'EUR 42,00-' 'Eu 42,00-'

This file and suggested fix are identical in at least freebsd-8.
Backport might be appropriate but some expert on locales should
probably have a look at us defaulting to negative numbers in
parenthesis when LC_* is default. That doesn't look right and is not
what other OSes are doing.
