`standard::name` must be available for `g_file_enumerator_get_child()`
to work. Emit a critical warning and return if it’s not. This is similar
to the existing behaviour in `g_file_enumerator_iterate()`.
Improve the documentation to mention this.

Fixes: #2507
The code cannot function correctly if the `standard::name` attribute is
not present, so upgrade the existing warning to a critical warning and
return if it fails in `g_file_enumerator_iterate()`.

Helps: #2507
It was Red Hat specific when it was introduced in 2004, was never
supported by mount(8) upstream, and was removed entirely in 2008.
It’s confusing for GLib to keep references to it around.
Thanks to Karel Zak for digging up the history of it:

And thanks to Xidorn Quan for looking into it in the first place (see
!2298).

The "recursive:" kwarg is available in the targeted minimum version of
meson, and is basically required if you want to not emit warnings and
maybe error with --fatal-meson-warnings.
There are two basic solutions to this problem:
- The current default behavior is false, so explicitly opt in to that
value. None of these internal libraries use recursive objects anyway.
- Use link_with to link to the static library directly, rather than the
extracted objects.
Option 2 is what used to be done before commit
62af03bda8, but it only works with meson
>=0.52 and previously had buggy behavior.
Since the minimum version of meson is now 0.52, it is safe to revert
that commit and go back to using link_with, and therefore option 2 is
chosen.

Despite their type, the values returned will always be ≥ 0. It’s
unfortunate they weren’t declared with an unsigned type, but we can’t
change that now without breaking API.
