This adds a simple block layer to barebox. Reading and writing
to block devices can be painfully slow without caching, so
add a simple caching layer here.

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.

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.

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

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.

Memory layout can now be specified via kconfig options. Two
possibilities exist: default layout means the layout is stack

for each TEXT_BASE / stack / malloc heap.

This patch makes TEXT_BASE a consistent per-arch config switch.
Additionally, it converts all TEXT_BASE occurences from string to hex.

- do more POSIX:
- use DIR instead of struct dirent
- use (struct dirent)->d_name instead of (struct dirent)->name
- switch to a new layout for U_BOOT_CMD:
- use C99 initializers to be able to add more fields to the
command struct
- add aliases for commands (needed mainly for help -> ? and test -> [
- This is not done for all commands yet, but the compiler will tell you ;)
some main.c cleanup:
- move the parser used when hush is disabled to parser.c
- move readline related functions to readline.c (with cmdline editing)
and readline_simple.c (no cmdline editing)
