Add --list-archive FILE support to localedef.
This feature largely supports the integrated work
for InstLang support, and does not explicitly change
any help text or behaviour at the API level for these
routines. The basic purpose is to allow a file name to
propagate to through the internal APIs to be used instead
of the default locale archive. Given that build-locale-archive
links against copies of the internal API it can use these
non-public APIs without problem.

Fix failure load locale template.
The call to open_tmpl_archive was being passed a pointer to an
object allocated on the stack. The object on the stack is not
guaranteed to be initialized to zero so we need to minimally
initialize `fname' in the struct locarhandle to ensure that
open_tml_archive loads the default tempalte.
This error was seen while debugging glibc installs in a qemu
VM where it is more likely the stack pages were dirty. It has
not been reported on non-VM systems.

Allow fill_archive to be called with NULL fname.
The fill_archive function should support being
called with a NULL fname argument. A NULL fname
argument indicates that the default archive should
be opened. We enable this by setting ah.fname to
NULL before initializing ah or calling open_archive.
This way if fname is NULL then ah.fname remains NULL
and open_archive opens the default archive.

[snip]
- Support `--list-archive FILE' in localedef utility.
This landed upstream in:
commit 484c12fb1e3664fb434291234ea5787c5e3df4f5
Author: Carlos O'Donell <carlos@redhat.com>

Enhance localedef --list-archive option.
The localedef --list-archive option claims that it can
accept a [file] argument and list the contents of that
archive. The support was never implemented. This patch
adds that support and allows --list-archive to work as
expected. You can now use localedef to list the contents
of arbitrary locale archives by using:
./localedef --list-archive file
The defaultfname flag was removed there, see
<https://sourceware.org/ml/libc-alpha/2013-10/msg00127.html>.
