output: use '[0m' to reset colors ...

'[m' is supposed to have the same effect as '[0m'. However, some EFI
implementations seem to ignore '[m', so use '[0m' everywhere to avoid
rendering issues.

menu: sanitize menu_add_title ...

passing a string to menu_add_title() which then gets free by this
function is just plain ugly. Pass it a const char * which gets
duplicated in menu_add_title() when necessary.

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.
