Creating a `GAppInfo` from a commandline isn’t currently supported on
macOS, but the implementation was incorrectly returning `NULL` without
setting the `GError`.
This was being caught by the new tests in `gio/tests/file.c`.

On macOS the comparison was failing as one of the paths had a trailing
slash while the other didn’t.

In `g_data_remove_internal()`, call the `GDataElt:destroy` functions in the
order that they appear in `keys`, instead of the order that they are found in
`datalist`.

We used to do get and set atomic operations pair, but these may be
unsafe in some cases as threads may rely on data that is changed in
in between them, however this is not a problem if we do exchange the
pointers.
So just use exchange ops, in this way we can avoid lock/unlock mutex
dances
We can use pointer exchange now to avoid doing two operations to switch
to the new data pointer.
Since we're asserting in case of invalid data, we can just do this check
at later point, without involving any different behavior.
This changes in the unlikely case that G_DISABLE_ASSERT is defined, as in such
case we should undo the operation.
Clang seems to apply more rigorous type checks across the different
arguments to the atomic builtins. Fix various
`-Wincompatible-pointer-types`, `-Wpointer-sign` and `-Wint-conversion`
warnings.

This makes calls to g_signal_connect_data() and g_signal_connect_object()
with default flags more self-documenting.

This makes code that sets no flags a bit more self-documenting:
using G_TYPE_FLAG_NONE makes it clearer that no special behaviour is
required than literal 0, and clearer that there is no weird casting
between types than (GTypeFlags) 0.
GTypeFlags and GTypeFundamentalFlags occupy the same namespace and the
same bitfield, so I intentionally haven't added
G_TYPE_FUNDAMENTAL_FLAGS_NONE.

The references to gint and guint were copy/pasted from
g_atomic_int_exchange(), but what we want here is a gpointer, gintptr
or guintptr like the rest of the g_atomic_pointer_ family.

Atomic primitives allow to do conditional compare and exchange but also
to get the value that was previously stored in the atomic variable.
Now, we provided an exchange function that allows to do an exchange if
the atomic value matches an expected value but we had no way to know
at the same time what was the value in the atomic at the moment of the
exchange try, an this can be useful in case that the operation fails,
for example if the current value is still acceptable for us, allowing
to do a kind of "OR" check:
gint old_value;
gint valid_value = 222;
while (!g_atomic_pointer_compare_and_exchange_value (&atomic,
valid_value, 555,
&old_value)
{
if (old_value == 555 || old_value == 222)
valid_value = old_value;
}
