Jean-Christophe PLAGNIOL-VILLARD a47575911d Menu: add box style entry 
this will allow you to create a box style entry

via C API by specifying the type as

struct menu_entry me = {
	.display "test",
	.type = MENU_ENTRY_BOX,
	.box_state = 1,
	.action = action_to_run,
}

and via shell
menu -e -a -m <menu> -c <command> [-R] [-b 0|1] -d <description>
menu -e -a -m <menu> -u submenu -d [-b 0|1] <description>

-b with 0 for not selected and 1 for selected
and -c for the command to run when changing state

Sascha Hauer 0d35c3c8a0 menu: simplify usage for clients 
Clients now only have to call menu_add_submenu or menu_add_command_entry
instead of allocating many strings.
This also fixes some problems in the menu code. The priv field in struct
menu_entry was a pointer to struct menu or a pointer to an allocated string.
It was never freed, only had to be freed when it was an allocated string.
The reference to a submenu is now kept as a string and not to the menu
itself. The code checked the existence of the submenu when creating it, but
crashed when the submenu was removed and referenced afterwards. Now the
code hapily allows references to nonexistant menus but complains during
runtime when the menu is not there.

menu -a -m boot -d "Boot Menu"
menu -a -m network -d "Network settings"
menu -e -a -m network -u boot -d "Back"
menu -e -a -m boot -u network -d "Network settings ->"
menu -e -a -m boot -c reset -R -d "Reset"
menu -e -a -m boot -c clear -d "Exit"
menu -s -m boot

in C

struct menu m_boot = {

	.display = "Boot Menu",
};

struct menu m_network = {
	.name = "network",
	.display = "Network settings",
};

struct menu_entry e_to_network = {
	.display = "Network settings ->",
	.action = menu_action_show,
	.priv = &m_network,
};

struct menu_entry e_to_boot = {
	.display = "Back",
	.action = menu_action_show,
	.priv = &m_boot,
};

struct menu_entry e_reset = {
	.display = "Reset",
	.action = menu_action_run,

};

void menu_test(void)
{
	menu_add(&m_boot);
	menu_add(&m_network);
	menu_add_entry(&m_boot, &e_to_network);

Jean-Christophe PLAGNIOL-VILLARD b712b26632 Add Menu Framework 
Introduce a menu framework that allow us to create list menu to simplify
barebox and make it more user-frendly

This kind of menu is very usefull when you do not have a keyboard or a
serial console attached to your board to allow you to interract with
barebox

For the develloper part,
The framework introduce two API

1) C
that allow you to create menu, submenu, entry and complex menu action

2) Command
that allow you as the C API to create menu, submenu, entry and complex
menu action but this time the actions will be store in a function and
then be evaluated and excecuted at runtime.
