The main GDK thread lock is not portable and deprecated.
The only reason why gdk_threads_add_timeout() and
gdk_threads_add_timeout_full() exist is to allow invoking a callback
with the GDK lock held, in case 3rd party libraries still use the
deprecated gdk_threads_enter()/gdk_threads_leave() API.
Since we're removing the GDK lock, and we're releasing a new major API,
such code cannot exist any more; this means we can use the GLib API for
installing timeout callbacks.

We need to have two lists: one, with the list of sources that need to be
introspected; and one with the list of sources that contain only private
symbols.
This reduces the amount of source files that the introspection scanner
needs to traverse, and thus the build time.
After commit ffef28a7e8,
gtk-icon-browser was spewing critical warnings when
changing sections. Avoid that by respecting the return
value of gtk_tree_model_get_iter.
GtkGesture is a GtkEventController. gtk_event_controller_dispose() calls
_gtk_widget_remove_controller(). That NULLs the pointer-to-Controller in
our EventControllerData but does not delete said ECData from our GList.
Subsequently, if that same Widget gets unparent()ed, that method calls
unset_state_flags(), which leads to doing reset_controllers() if we are
insensitive. Now, unlike most most other loops over the GList of ECData,
reset_controllers() does not skip nodes whose pointer-to-Controller is
NULL. So, we call gtk_event_controller_reset(NULL) and get a CRITICAL.
This surfaced in a gtkmm program. The Gesture is destroyed before the
Widget. The Widget then gets dispose()d, which calls unparent()… boom.
I didn’t find an MCVE yet but would hope this logic is correct anyway:
The simplest fix is to make the loop in gtk_widget_reset_controllers()
skip GList nodes with a NULL Controller pointer, like most other such
loops, so we avoid passing the NULL to gtk_event_controller_reset().
In other, live cases, _gtk_widget_run_controllers() loops over the GList
and removes/frees nodes having NULL Controllers, so that should suffice.
But this clearly was not getting a chance to happen in the failing case.

Otherwise, gtk_widget_get_window returns NULL and we can't successfully
perform a grab via the later gdk_set_grab call. This fixes the entry
completion in the file chooser not working.
Filter models rely on views taking a ref on every node
they care about. GtkIconView was not doing that. Amazingly,
this has never shown up in a bug so far, until I spotted
the fallout in gnome-font-viewer.
This was causing us to leak, in the following scenario:
1) gtk_widget_destroy is called on a GL area
2) dispose is run and clears the context
3) the GL area is unrealized, but the context is already cleared,
so we leak all the GL buffers
Handle the situation that a GL texture might remain
in use (e.g. by a slow frame, or by the recorder)
In that case, we can't modify it but must use a
new one. Keep a pool of GL textures for this eventuality.
g_list_model_get_item is transfer full, so we need
to drop the references we get from it. This was showing
up while testing the GL texture cache in GtkGLArea.
We already check right before this one whether child->pack != packing
and if so, we continue to the next iteration. So, no need to check again
whether the inverted condition child->pack == packing is true, because
it is.
