The idea is to panic() when there is no memory available for normal
operation. Exception: code which can consume arbitrary amount of RAM
(example: files allocated in ramfs) must report error instead of panic().
This patch also fixes code which didn't check for NULL from malloc() etc.
Usage: malloc(), memalign() return NULL when out of RAM.

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.

2) Command

The old network stack has some bad limitations:
- network commands are required to call NetLoop() which only returns when
the network layer wants to. Instead we now use a net_poll() function which
returns after handling one packet (or immediately if no packet is
available).
- There can be only one packet handler which makes it impossible to handle
multiple connections
- CamelCaseMakesItHardToRead
The new network stack is implemented as a parallel universe. Currently all
commands still use the old stack. They are converted in subsequent patches.

We used to eth_open/eth_halt the network devices during NetLoopInit
which is called whenever the user enters a network command.
Change this behaviour so that the current network device gets opened
when making it the current one.
With this change it's always possible to send packages and we are able
to implement a new network stack in the next step.
