It is cleaner to define glib_typeof() in a header included after
gversionmacros.h so we can use GLIB_VERSION_MIN_REQUIRED directly
instead of doing it everywhere glib_typeof() is used.
The `GApplication` must be registered before calling
`g_application_mark_busy()`. Document that, and add a guard.
The same is true for `g_application_unmark_busy()`, but the existing
documentation and guard for `busy_count > 0` are enough.
If libintl is built statically on macOS, linking it requires passing
"-framework CoreFoundation" to satisfy symbol dependencies. Use the
available osx_ldflags already detected earlier in the process.
Rather than always writing to `out.xbel` in the build directory, which
could cause issues when running tests in parallel, or expecting the
tests to not touch the build directory.

Rewrite bookmark_item_dump to not crash if any of
the timestamps is NULL. Also, avoid some of the gratitious
extra string copying.
Tweaked by Philip Withnall to pass the unit tests.
For the reasons given in the new bit of documentation, GDBusProxy should
not be used for connecting to stateless D-Bus services which may be
restarted at any point.

Include the base URI in the `g_test_bug()` calls instead. This resolves
inconsistencies between the old bug base (bugzilla.gnome.org) and the
new bug base (gitlab.gnome.org). It also has the advantage that the URI
passed to `g_test_bug()` is now clickable in the code editor, rather
than being split across two locations.

Currently, `g_atomic_ref_count_dec ()` does two operations.
We try to get this down to one operation.
Replace `g_atomic_int_dec_and_test ()` with `g_atomic_int_add ()`
Passing -1 as value.
Note: changes current behaviour, checks are now done after decrement.
This seems non-obvious to me. Document it.
It also seems important to know, because it means that the data pointer
might already be destroyed, before the source is unreferenced for good.
For example, if the data pointer keeps a reference to the GSource,
and it might seem sensible to call:
g_source_destroy(data->source);
g_source_unref(data->source); /* <<< data is already destroyed? */
This leads to a crash, if the source was attached to a context.
Since commit ab285899a6 ('gdbusconnection: Document main context
iteration for unsubscript'), we document when the user is guaranteed
that all resources are gone after g_dbus_connection_signal_unsubscribe().
This is not merely an implementation detail, it's something that the
user needs to be able to rely on. It is good that this is documented.
However, libnm does something different ([1]). It registers to several D-Bus
signals without providing a GDestroyNotify. After unsubscription, it schedules
another idle action with lower priority and uses that to know when
cleanup is complete. I think this is a useful alternative and should
also be guaranteed and documented to work.
Also note that this isn't just some implementation detail that currently
happens to work. GDBusConnection tightly integrates with GMainContext and it
works by scheduling idle sources with G_PRIORITY_DEFAULT priority. It needs to
schedule all events with this same priority, otherwise the ordering is not
preserved. At this point, with GDBusConnection working this way, this is no longer
something that can reasonably be any different. It's how GDBusConnection fundamentally
works, and a user must be able to rely on that. As such, this new promise isn't
something that we would want to break in the future.
Thus document it.

Currently, `g_atomic_ref_count_inc ()` does three operations.
We try to get this down to one operation.
Fixed by replacing `g_atomic_int_inc ()` with `g_atomic_int_add ()`
which increments by 1 and returns old value
Note: changes current behaviour, checks are now done after increment.
Closes: #1583
