This fixes commit cdcb179808.
`dn_comp()` is needed to build fake DNS records for most of the tests in
this file. The new ownership test is no exception.

fb58d55187 added weak linking for ASAN,
skipping it for MinGW because weak symbols are broken there.
The same is true for Cygwin, so skip things there too.
This fixes the following build error under MSYS2:
/usr/lib/gcc/x86_64-pc-msys/13.3.0/../../../../x86_64-pc-msys/bin/ld:
glib/msys-glib-2.0-0.dll.p/gutils.c.o:gutils.c:
(.rdata$.refptr.__lsan_enable[.refptr.__lsan_enable]+0x0): undefined reference to `__lsan_enable'
On Linux the error will be `G_IO_ERROR_CONNECTION_REFUSED`, but on macOS
it will be `G_IO_ERROR_TIMED_OUT`. Both errors seem reasonable to me, so
let’s not specifically require one of them.

There are a couple of places in the code which use `isnan()` and have
platform-specific workarounds for it. Unify those, and extend the
workaround to work for msys2-mingw32.
It seems that msys2-mingw32 can’t automatically use `isnan()` in a wider
mode than `float`:
```
In file included from ../glib/gdatetime.c:60:
../glib/gdatetime.c: In function 'g_date_time_new':

See: https://gitlab.gnome.org/pwithnall/glib/-/jobs/4022715
Using it in float mode on all platforms should not change behaviour, as
a conversion from `(double) NAN` to `float` should still give `NAN`.

This should have been dropped in commit
38faeca62e but somehow that didn’t happen
and somehow it wasn’t caught by the CI until afterwards.

For each test expected to return valid DNS records, test that the
record variants are not floating references.
Also add an test which checks this explicitly for a simple TXT record.
The return value to `lookup_records()` methods is set as `transfer full`
but the code path in `g_resolver_records_from_res_query()` doesn't
sink the GVariant.
Add the `g_variant_ref_sink()` call when prepending the record, so
the list hold a full reference on each records.

It’s deprecated, but I was modifying it anyway and it didn’t have any
coverage, so let’s add a simple test (as suggested by Michael
Catanzaro).

- Add licensing tags
- Tweak spacing, colors, line thicknesses
- Create light-mode version
- Use `<picture>` tag to include appropriate version for each media
color scheme.
Recreate the `menu-model.png` diagram in SVG, with box outlines and
connectors recolored from black to white. This will allow the diagram
to show up better in the dark documentation theme.
gnulib doesn’t work with it, and if we try and enable it then mingw
versions of `signbit()` start causing problems.

While an index greater than `G_MAXINT` can’t be passed to
`g_ptr_array_insert()`, `-1` can be — and if that’s done with an array
which has more than `G_MAXINT` elements in it, the new element will be
inserted part-way through the array rather than being appended.
Spotted by building with `-Wsign-conversion`.

The latter only accepts a `gint` as the number of elements in the array,
which means that its use in `GArray` (and related array implementations)
truncates at least half the potential array size.
So, introduce a replacement for it which uses `size_t` for the number of
elements. This is inline with what `qsort()` (or `qsort_r()`) actually
does. Unfortunately we can’t directly use `qsort_r()` because it’s not
guaranteed to be a stable sort.
This fixes some `-Wsign-conversion` warnings (when building GLib with
that enabled).

GLib now compiles without emitting any float conversion warnings, so
let’s keep it that way.
