GtkAssistant supports not showing the sidebar with the page
titles (if the page have no titles). Unfortunately, we were
hiding the sidebar in this case, but still rendering the frame
behind it, leading to a broken appearance.
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.

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.
Make page titles left-aligned again. Changing from misc alignment
to GtkWidget::halign here was a mistake. We can't do that for labels
in a size group, as long as labels still pay attention to misc
alignment.

This has mostly two advantages:
- the most obvious one is the theme can render a border around the
sidebar if it wants to.
- we also can avoid hardcoding a container border width for the sidebar,
and just use a padding from the theme. This also allows different
themes to define a different padding, etc.
The drawback is we must draw the background ourselves, but it's easy
enough.

GtkAssistant is widely recognized as a butt-ugly widget.
This commit changes its style to look more modern. We
deprecate the sidebar and header image properties and
don't show them anymore. Instead, page titles are arranged
in a sidebar, with the title of the current page shown
in highlighted style.
ATK provides macros to the same effect as G_DEFINE_TYPE; using these
macros has the advantage of removing tons of duplicated code and
reducing the maintainership burden.
The widgets with inline accessibility implementation should switch to
these macros, and clean up the code.
