Now that roots can have parent widgets, we need to
carefully examine all calls of gtk_widget_get_toplevel,
and replace them with gtk_widget_get_root if we want
the nearest root, and not the ultimate end of the parent
chain.
We now rely on toplevels receiving and forwarding all the events
the windowing should be able to handle. Event masks are no longer a
way to determine whether an event is deliverable ot a widget.
Events will always be delivered in the three captured/target/bubbled
phases, widgets can now just attach GtkEventControllers and let those
handle the events.
And ensure it's still visible before returning the keyboard focus to it.
Because of the extra ref, add a dispose handler that will ensure the
ref is lost (by popping down), although this should be already ensured
through other paths (eg. when the popup widget loses visibility).
This fixes a possible crash in dispose paths, where we might be restoring
focus on an already destroyed widget, and at a time where, if the toplevel
is being itself disposed, no new focus should be set.

Don't make the popup follow the slider while it is open; that
makes interaction with it unnecessarily hard. Also move all the
popups inwards a little bit, so they are not flush with the
scales, which looks untidy.

Use a .activatable style class on the color swatch and tie the
hover effect to it. The color editor simply removes this class
now to get an inert color swatch.
This is more flexible and lets us avoid referring to the
GtkColorEditor type in the theme.
We rename the gtk_widget_class_bind_template_child{_internal}
macros by appending a _private to their name. Otherwise, it
would be too magic to pass the 'public' names as arguments,
but affect a member of the Private struct. At the same time,
Add two new macros with the old names,
gtk_widget_class_bind_template_child{_internal} that operate
on members of the instance struct.
The macros and functions are inconsistently named, and are not tied to
the "template" concept - to the point that it seems plausible to use
them without setting the template.
The new naming scheme is as follows:
gtk_widget_class_bind_template_child_full
gtk_widget_class_bind_template_callback_full
With the convenience macros:
gtk_widget_class_bind_template_child
gtk_widget_class_bind_template_child_internal
gtk_widget_class_bind_template_callback

Using an offset from the struct means you can have children in
both the public and private (via G_PRIVATE_OFFSET) parts of the
instance. It also matches the new private macros nicer.

Deprecate gtk_widget_push_composite_child, gtk_widget_pop_composite_child,
gtk_widget_set_composite_name, gtk_widget_get_composite_name.
This API is just bloat and was never useful, this patch deprecates
it and removes all internal calls to the composite child APIs
In particular gtksettings.h and gtkstylecontext.h needed to be included
in lots of places now.
Also, I order the includes alphabetically in a bunch of headers.
