menu: Add support for user defined item choice function

Browse source 
Selecting menu items is currently done in menu_interactive_choice()
by reading the user input strings from standard input.

Extend menu_interactive_choice() to support user defined function
for selecting menu items. This function and its argument can be
specified when creating the menu.
