Make some use of anonymous unions [pg_locale_t]
...
Make some use of anonymous unions, which are allowed as of C11, as
examples and encouragement for future code, and to test compilers.
This commit changes the pg_locale_t type.

Change wchar2char() and char2wchar() to accept a locale_t.
...
These are libc-specific functions, so should require a locale_t rather
than a pg_locale_t (which could use another provider).

Remove provider field from pg_locale_t.
...
The behavior of pg_locale_t is specified by methods, so a separate
provider field is no longer necessary.

Control ctype behavior internally with a method table.
...
Previously, pattern matching and case mapping behavior branched based
on the provider. Refactor to use a method table, which is less
error-prone.
This is also a step toward multiple provider versions, which we may
want to support in the future.

Use thread-safe strftime_l() instead of strftime().
...
This removes some setlocale() calls and a lot of commentary about how
dangerous that is. strftime_l() is from POSIX 2008, and on Windows we
use _wcsftime_l().
While here, adjust error message for strftime_l() failure: it does not
in practice set errno (even though POSIX says it could), so no %m.

Previously, behavior branched based on the provider. A method table is

The ctype behavior will be addressed in an upcoming commit.

buffer. Then, move provider-specific logic into pg_locale_builtin.c,
pg_locale_icu.c, and pg_locale_libc.c as appropriate.
