Here's a patch set v2.

I changed it so that the pg_locale_t itself a resource kind, rather
than having separate locale_t and UCollator resource kinds. That
requires a bit more care to make sure that the pg_locale_t can be
initialized without leaking the locale_t or UCollator, but worked out
to be simpler overall.

A potential benefit of these changes is that, for eventual support of
multi-lib or an extension hook, improvements in the API here will make
things less error-prone.
