Fix usage of __LITTLE_ENDIAN macro.
Both __LITTLE_ENDIAN and __BIG_ENDIAN are always defined by
include/linux/byteorder/generic.h, checking for their existence is
pointless.

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.

Currently we have duplicated all the information that appears online in
'help <command>' and in the doxygen documentation. This patch adds some
infrastructure to specify help texts only once and re-use them for the
integrated help as well as for the manual.

Don't let doxygen parse the command magic, which leads to these warnings:

The function names do not make it clear what return value
is expected and do not save a single line of code. Put
the code inline and unbreak the wrong checks introduced
with a3c1e5d888.

this will allow you to create a box style entry
via C API by specifying the type as
struct menu_entry me = {
.display "test",
.type = MENU_ENTRY_BOX,
.box_state = 1,
.action = action_to_run,
}
and via shell
menu -e -a -m <menu> -c <command> [-R] [-b 0|1] -d <description>
menu -e -a -m <menu> -u submenu -d [-b 0|1] <description>
-b with 0 for not selected and 1 for selected
and -c for the command to run when changing state
