The with_separators argument does not really make sense
for popovers, it was just copied from the menu implementation.
Drop it now, before it becomes part of the public API.
cairo_rectangle_int_t replaced by GdkRectangle whenever it is used.
Also, rect parameter in public method gtk_popover_set_pointing_to
made const.
Bug #723394
This adds a new function, gtk_popover_new_from_model, which creates
a popover and populates it with suitable content according to the
menu model. The current implementation uses GtkModelButton for the
individual items, and a GtkStack for submenus.

This property is TRUE by default, when a popover is modal, it
will automatically set a GTK+ grab on the popover, and grab
the keyboard focus into the popover.
