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.

Change device parameters so that the memory management is in generic
code. This also removes the need of storing statically initialized
parameters as they are stored in a struct list_head for each device.

v2: Do not exit from all scripts but only the current one
This fixes the case:
barebox:/ cat /test
if [ 0 = 0 ]; then
exit 1
fi
barebox:/ /test
barebox:/ echo $?
0
barebox:/
Also, remove code to not allow exit from main shell. The for(;;) loop
in common/startup.c will bring us back anyway.

The correct config variable is CONFIG_MODULES, so tweak any references
to the incorrect CONFIG_MODULE.

Memory allocation is very simple in u-boot-v2. So, it makes also sense to
add the "operating system" emulation layer into the main memory management
source file, to keep them at one place and simple.

Don't try to be smarter than GCC. There are various better optimizations
available than to write our own. So, use the globaly available string
functions instead.

When assert() is always defined to do nothing, the debug functions makes no
sense, because they also do nothing. Removing them shrinks the code.

Use a function prototype style as used in all other u-boot-v2 sources, too.
Also remove C++ support. We do not use C++ in this project.

This feature is provided, to support more than u-boot-v2. But its more
confusing than helpful. Remove it and do it straight forward like all other
sources in this tree, too.

Include the board config first to be able to configure the memory management
in the documented way. If not used, the defaults are used.
On the other hand, there is no need to pollute the other source files with
these local management settings. So, move them from the header into the
C source file.

There is no need to init variables with 0. So, move them to the bss and let
the C runtime does this job for us.

Any wrong or unknown command will result into the output:
Unknown command '<some text>' - try 'help'
If the command 'help' is disabled, this will end up in:
Unknown command 'help' - try 'help'
which is for blondes. Suppress the "try 'help'" for the case the 'help'
command is disabled.

We accidently have two list implementations in the tree:
include/list.h and include/linux/list.h. This patch moves
the latter (newer one) to include/linux/list.h.

No need to check for maximum argument counts. The commands are
safe to be called with more arguments, so lets safe some bytes.

This allows us to return COMMAND_ERROR_USAGE for
a failed command which will then print the usage,
a very common case for commands.
