The constant size request mode defines a request mode where
height-for-width geometry is unneeded, thus optimizing GTK+
by reducing the overall amount of requests that need to be
performed and cached while resizing an interface.
I've decided that it is isn't feasible to make cell areas runtime-settable
in the time we have left before 3.0, therefore, I'm going with the
approach to allow init() functions to instantiate the default cell area
and issue a warning if a construct property is ignored.
This is not ideal, but it keeps existing icon view and combo box
subclasses working.

- Removed GtkTreeMenu from gtk-docs.sgml
- Removed GtkTreeMenu from gtk3-sections.txt
- Removed GtkTreeMenu from gtk.symbols
- Make GtkTreeMenu apis prefixed with '_' (including _get_type()).
- Updated GtkComboBox sources to use the private apis
- Updated GtkCellView to not mention #GtkTreeMenu in gtk-doc statements
- Updated tests/testtreemenu to not use a GtkTreeMenu but still
show a very fancy GtkComboBox
- Moved gtktreemenu.h to private headers section in the makefile.
- Removed include of gtktreemenu.h from gtk.h
APIS: gtk_cell_view_get_desired_width_of_row &
gtk_cell_view_get_desired_height_for_width_of_row were introduced in
3.0 only for use from GtkComboBox and now the refactored cellview
does this transparently and just requests the right thing through
GtkWidget apis.
First iteration at implementing combo box using a delegate
treemenu, almost everything is working. Still need to finalize
sensitivity issues in GtkTreeMenu (and should go ahead and pass
through GtkComboBox code with a fine comb...).
- "fit-model" decides that the cellview should request space for
the entire treemodel, this ensures the cell view displayed on
a combo box will not spuriously change size when the selected
item changes.
- "draw-sensitive" forces cell area to render cells sensitive
even if they are insensitive in the model.
When the "row-changed" signal on the model is trapped, if the row which
changed is the displayed row then the context is flushed and sizes are
recalculated for every area in the same context.
Added construct GtkCellArea and GtkCellAreaContext properties,
the context property allows putting multiple cellviews into the
same size request context.
