menu: add support to check if menu needs to be reprinted

This patch adds a new callback named need_reprint for menu.
The need_reprint will be called before printing the menu. If the
callback exists and returns FALSE, menu printing will be canceled.

This is very useful if the menu was not changed. It can save time
for serial-based menu to handle more input data.
