menu -e -a -m <menu> -c <command> [-R] [-b 0|1] -d <description>

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.

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.

[Patch 02/17] U-Boot-V2: Handle case of clock rollover for get_time_ns
get_time_ns does a simplistic delta = cycle_now - cycle_last. It is possible that the h/w counter reached max and reset back to 0.
This patch addresses this issue by checking for rollover condition.
NOTE 1: This does not guarentee that you cannot confuse get_time_ns. You could possibly wait for two reset cycles and then get a messed up value.
To fix that we may need interrupt mode timer tick - something on the lines of jiffies on linux.
NOTE 2: the question of cs->mask is not clear. if the mask is for the tick, then it is better done with (cycle_now & cs->mask) - (cs->cycle_last & cs->mask).
