$(DEFAULT_ENVIRONMENT_PATH) expands to 'defaultenv "" '
The "" would cause every single file found in $(srctree) to be included in
$(ENV_FILES). This would then cause scripts/mod/sumversions.c to get
recompiled using $(CC) and fail compilation if $(CC) points to a newlib
cross compiler

Barebox does not have interrupt functionality. Nevertheless it's
sometimes useful to periodically call functions, like for example
a heartbeat LED or watchdog reset. Instead of cluttering the code
with calls to these functions this patch adds a generic polling
infrastructure. Code which might run for longer now can call
poller_call() periodically which in turn will call all registered
pollers.
This patch adds a call to poller_call in two generic pathes. First
of them is getc() which covers waiting for uart input. Second is
ctrlc() which should be called anyway from code which might run
for longer. So instead adding poller_call directly to your code,
consider checking ctrlc instead which also gives additional
convenience to the user.
The poller code is safe against reentrancy which means that it's
safe to call poller_call inside a poller.

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.
