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`.

Closes: #1879
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.

Fixes: #1309
Since we transitioned from Bugzilla to GitLab, we have two forms of bug
references in the GLib source code: old (but still relevant) Bugzilla
links, and newer GitLab links. We can’t use a single base for the two,
so have to either build incorrect URIs, or provide the full URI in
g_test_bug().
It’s always seemed a bit of an over-optimisation to provide the bug base
separately from the bug ID, so relax the assertions and documentation
around g_test_bug_base() so that g_test_bug() can be used on its own.
The old usage patterns are still supported unchanged.
