These macros wrap functions which were only introduced in certain
versions of GLib. The functions are correctly marked as introduced in
those versions, but the macros aren’t, which can result in not getting
appropriate deprecation warnings if you’re using those APIs when you
have said you’re targeting older GLib versions using
`GLIB_VERSION_MAX_ALLOWED`.

We require a newer SDK version now, so this is not needed.
Specifically, we set _WIN32_WINNT to 0x0601, which sets our SDK
requirement to Windows 7+, and this code is only needed for MSVC 5.0,
which is ancient.
It’s confusing and often doesn’t help the user. Match the error code and
come up with a more UI-appropriate error message.

This fixes use of `GIO_USE_VOLUME_MONITOR=help`, and simplifies the
code. The reason this wasn’t used already seems to just be because it
was missed when `_g_io_module_get_default_type()` was introduced in
2013. The previous `get_default_native_class()` code in
`gunionvolumemonitor.c` was introduced in 2007.

If the dup(stderr) returns '-1' (an error occured), then the program
shouldn't call a 'close(stderr); dup(old_err);' after the exec() failed.
Fix issue #1880
Various memory allocations are still reachable when a process exits, as
they contain type system information which can’t be unloaded. Suppress
those using `glib.supp`.

A static analysis run noted that we weren't freeing the cmdline in the
error path here. We can just make this an assertion instead; I just
checked the kernel code, and it just usees a seq_printf() here which
will NUL terminate.
This fixes the following warning, by making the compiler checks for the
`pop` match those for the `push`:
```

When g_variant_get_child_value() is called for a child whose
serialisation is an empty byte string (which is possible), `bytes_data`
will be non-`NULL`, but `data` may be `NULL`. This results in a negative
offset being passed to `g_bytes_new_from_bytes()`, and a critical
warning.
So if `data` is `NULL`, set it to point to `bytes_data` so the offset is
calculated as zero. The actual value of the offset doesn’t matter, since
in this situation the size is always zero. An offset of zero is never
going to cause problems.

These are copies of the existing tests for `g_time_val_from_iso8601()`,
with the test strings which fail for `GDateTime` commented out. This is
OK, as it’s documented as only accepting a subset of ISO 8601 (and for
some of the test vectors, it’s debatable whether they’re actually valid
ISO 8601, depending on how you interpret the valid bounds of timezone
offsets — some interpretations of the available documentation would say
that timezone offsets should never be ≥24 hours or ≥60 minutes).
There is one test string which is not accepted by
`g_time_val_from_iso8601()` but which is accepted by `GDateTime`, as
`g_date_time_new_from_iso8601()` actually accepts RFC 3339, which is a
little more liberal than ISO 8601. Fun times. See
https://tools.ietf.org/html/rfc3339#section-5.6.

Some malformed ISO 8601 date/time strings were causing an assertion
failure when passed to `g_date_time_new_from_iso8601()`, due to a
mismatch between the bounds checking of timezone offsets in `GDateTime`
and `GTimeZone`. Fix that and add a unit test for it.
