Support popping up tooltips on demand

Description
There have been several requests for making it possible to popup tooltips on demand. Examples:
- The tooltip on the "Start" menu in Windows,
- Notification balloons (these are not necessarily tooltips),
- etc. Also see the URLs in http://mail.gnome.org/archives/gtk-devel-list/2006-October/msg00019.html
Especially Windows applications seem to make use of this kind of "tooltips", personally I have never seen this on Mac OS.
We should decide whether we want to support this in GTK+, and whether this is an extension of the tooltips system or something different. Together with this we might want to add support for manual positioning, info banners, etc. Maybe the planned "controller object/interface" stuff will add bring support for this.
