Provide thread-safe pg_localeconv_r().
This involves four different implementation strategies:
1. For Windows, we now require _configthreadlocale() to be available
and work (commit f1da075d9a0), and the documentation says that the
object returned by localeconv() is in thread-local memory.
2. For glibc, we translate to nl_langinfo_l() calls, because it
offers the same information that way as an extension, and that API is
thread-safe.
3. For macOS/*BSD, use localeconv_l(), which is thread-safe.
4. For everything else, use uselocale() to set the locale for the
thread, and use a big ugly lock to defend against the returned object
being concurrently clobbered. In practice this currently means only
Solaris.
The new call is used in pg_locale.c, replacing calls to setlocale() and
localeconv().
