When future porting deprecated code to use
g_file_info_get_modification_date_time() we risk a number of breakages
because the current implementation also requires the additional use of
G_FILE_ATTRIBUTE_TIME_MODIFIED_USEC. This handles that situation gracefully
and returns a GDateTime with less precision.
Applications that want the additional precision, are already using the
additional attribute.
(Minor tweaks by Philip Withnall.)
This should make the code a bit easier to reason about, and squash some
static analysis warnings.

The macros for the probes confuse the static analyser, and are often
called with arguments which the analyser things shouldn’t be used any
more (for example, the address of a block of memory which has just been
freed).

These squash various warnings from `scan-build`. None of them are
legitimate bugs, but some of them do improve code readability a bit.

Instead of letting each directory to find its way to link with libdl,
it is easier to put the check in the top level, so its result can be
used by all directories.
It is a follow-up of https://gitlab.gnome.org/GNOME/glib/merge_requests/810.
The header file was installed when building using autotools, but was
inadvertently omitted in the meson targets.
Luckily, ABI is not impacted, since gnativesocketaddress.c was always
compiled and linked into libgio.

The gobject introspection comments have a reference to an incorrect
class: they have, as 'self', the GSubprocess class instead of
GSubprocessLauncher.
This patch fixes this.
g_settings_backend_watch() uses a weak notify for keeping track of
the target. There's an explanation why this is supposed to be safe but
that explanation is wrong.
The following could happen before:
1. We have the target stored in the watch list
2. The last reference to the target is dropped in thread A and we end up
in g_settings_backend_watch_weak_notify() right before the mutex
3. g_settings_backend_dispatch_signal() is called from another thread B
and gets the mutex before 2.
4. g_weak_ref_init() is called on the target from thread B, which at
this point has a reference count of exactly one (see g_object_unref()
where it calls the weak notifies)
5. Thread A continues at 3. and drops the last reference and destroys
the object. Now the GWeakRef from 4. points to a destroyed object. Note
that GWeakRefs would be cleared before the weak notifies are called
6. At some later point another thread g_weak_ref_get() is called by
g_settings_backend_invoke_closure() and accesses an already destroyed
object with refcount 0 from the GWeakRef created in 4. by thread B (or
worse, already freed memory that was reused).
Solve this by actually storing a GWeakRef of the target in the watch
list and only access the target behind it via the GWeakRef API, and then
pass a strong reference to the notification dispatch code.
The weak notify is only used to remove the (potentially with empty
GWeakRef) target from the list of watches and the only place that
compares the target by pointer instead of going through the GWeakRef
API.

If we fail to create a GWinhttpFile for a URI (for example, because it’s
an invalid URI or is badly encoded), don’t just return NULL. Instead,
fall back to the wrapped VFS which might be able to handle it instead.

It cannot return a NULL value, as none of its callers have error
handlng. Add an assertion to check the values returned by the VFS
implementations.

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.

This fix build error for projects that use gnome.compile_resources()
when glib is built as a subproject and not installed on the build
machine.
Note that this is not working for cross compilation cases, because it
would require to compile everything twice (for host and build machines).
A better solution would be to rewrite those tools in python. See #1859.
