We were not really handling all cases correctly here. We want
the suggested-action style class to only be set on headerbar
buttons, and it should be set on the default widget. Ensure
this by syncing the suggested-action style class with the
default style class. As a side-effect, setting has-default
on an action widget in ui files will now have the expected
effect.

GtkDialog has convenience API for adding action widgets that are
either placed in the action area or the headerbar. This commit
makes the same functionality available from GtkBuilder ui files
by specifying "action" as the child type.

The use of border-width-set here was an attempt to differentiate
between explicitly set (from code / ui files) border width from
theme changes. But when we are calling gtk_window_set_border_width
to apply the theme value, the -set property gets set, and all
further theme changes are ignored. This has the effect of only
letting the default value of these properties get applied.
Fix this by unsetting border-width-set after applying theme values.
This fixes an issue where the theme-provided border-width prevents
dialog contents from lining up properly with the headerbar. To make
this work in message dialogs, we have to explicitly set the border-
width of the action area to 0.
We want to present a clean, rounded top when there is nothing
else to show, but many dialogs in applications rely on showing
information in their title, so add a label and show the title
when it is not empty.
If we aren't using a header bar then put a fake titlebar
box on it so we can round the corners.
One of the advantages of this is so that the styling of the dialog
is completely within one theme framework. This prevents skew between
the theming expectations from the window manager and GTK+.

Try to do a better job of keeping example content
from being too wide. It is often rendered as <pre>
text so the only time we can wrap it is in the source.
It is best to full break lines at all punctuation and
to try to keep the width under 70 chars or so.
This commit introduces a private convenience API that derived
dialogs can call in their instance init. This is necessary to
make the setting work as intended in the face of 3rd party
dialogs derived e.g. from GtkFileChooserDialog, which are
created with g_object_new.
This change makes it possible for GtkDialog to pack
its action widgets into a header bar, instead of the
traditional action area. This change is controlled
by the use-header-bar construct-only property.
