Ryan Lortie dd143479fe gtkmodelmenu: simplify logic, expose bind API 
Make the main (and only) entry-point to gtkmodelmenu.c the now-public
gtk_menu_shell_bind_model().

Move the convenience constructors (gtk_menu_new_from_model() and
gtk_menu_bar_new_from_model()) to their proper files.

Remove the private header file.

Simplify the code a bit by making the initial populate part of the
bind() call.
