add dummy_malloc functions ...

For some environments the dummy malloc functions offer a very small
alternative implementation. malloc will get its memory from sbrk()
and never frees memory again.
This of course is not suitable for interactive environments and thus
depends on CONFIG_SHELL_NONE

add noshell support ...

Some scenarios like initial bootloaders do not need interactive shell
support, so make this optional. Without a shell a board must provide
its own run_shell function.

This adds a simple block layer to barebox. Reading and writing

kallsyms/printk: enable symbol printing support (%pS) ...

With this kallsyms finally start working at least on ARM. This
enables us resolving addresses into symbols which is particularly
useful in combination with stack unwinding support. As kallsyms
now compile and work we can remove the depends on BROKEN.

Add generic poll infrastructure ...

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.

hush: implement getopt builtin ...

Positional parameters are not nice, so implement a getopt
function. This has to be done as a builtin because otherwise
we have no access to the parents argc/argv.

getopt works as expected, here is a little example:

while getopt "hs:" OPT
do
        if [ $OPT = h ]; then
                echo "usage"
                exit 1
        else
                echo "scr: opt: $OPT optarg: $OPTARG"
	fi
done

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.
