This commit add some more keyboard shortcuts to gtk3-widget-factory,
and adds a help overlay documenting them. This examle uses the
automatic resource loading support in GtkApplication.
GTK cannot depend on libcanberra-gtk which depends on GTK. This causes
a circular dependency and is especially neat if installed GTK is
different enough from uninstalled GTK.
To generate the icon cache files.
We want to avoid a dependency loop if possible; additionally, on some
Debian-based systems gtk-update-icon-cache maps to the GTK2 version of
the utility and the GTK3 version is renamed to
gtk-update-icon-cache-3.0.
To avoid a build dependency on GTK2, use the binary that we just built
in-tree.

As a noinst_PROGRAMS, the libtool generated for cross-compiling will be
used, which will mess up the linking. Create a all-local target instead.
Also ensure that building uses always a native version of the tool by
specifying a GTK_UPDATE_ICON_CACHE automake variable.
Finally "config.h" has been created to work for the target platform and
causes problem when cross-compiling. So we temporarily generate a basic
config.h which contains only the strict minimum.
Otherwise we fail to link, seeing this:
/usr/bin/ld: gtk3_widget_factory-widget-factory.o: undefined reference
to symbol 'gdk_pixbuf_new_from_resource'
