Introduce a 'custom-item-activated' on the widget, which behaves
similairly to GtkEntryCompletion::action-activated, i.e. is emitted when
a custom item is chosen from the dropdown list.
Clients can use the name provided when adding the item as a detail for
the signal, to get notified when that specific item is activated, or use
the signal without details to get notifications for all custom items.
The GtkSwitch widget is a simple UI control that has two states: on and
off. Toggling between the states is possible by clicking the widget or
by dragging the handle.

This commit adjusts the app chooser code to GTK+ coding style:
- line up prototypes
- remove some excess {}
- remove tabs and trailing whitespace
- add docs
It is really bad code, mostly unused and no one stepped up to fix it.
Note that Gtk developers do not object to a ruler widget in priciple,
just to the current implementation. If someone wants to propose a sane
version, please don't hesitate.

Like GtkFileChooser does; GtkOpenWith is a generic interface, which is
now implemented by both GtkOpenWithDialog and GtkOpenWithWidget (and in
the future also by GtkOpenWithComboBox).
This patch adds the GtkScrollablePolicy type property to GtkScrollable
and implements it in all subclasses. GtkScrolledWindow observes this
property to make a good guess about when to show/hide scrollbars for
height-for-width content.
Most scrollable children do not do height-for-width *yet* but
most certainly will (toolpalette, treeview, iconview, textview
widgets all TODO), for scrollable widgets that do have a minimum
and natural size, it's important for them to observe the state
of this property in order to properly drive the scroll adjustments
according to the desired GtkScrollablePolicy. This patch makes
GtkViewport do this.
Patch also adds tests/testscrolledwindow.c to display the effects
of this property.
alignment/margin vfuncs adjust_size_request/allocation
Now get_height_for_width() will internally update the for_width
before passing it to the real height_for_width() vfunc, allowing
margins and extra space for alignments to be stripped, thus requesting
sufficient height for greater than natural widths (and also accounting
for margins properly). Test case adjusted in testadjustsize to ensure
proper behavior.
