"ifconfig" and "ip" from normal Linux userspace shows ethernet addresses
normally in lowercase. And the %pM format specifier in Linux does that,
too. Conform to this custom formatting.

In barebox network packets always go out at the current ethernet
device and are expected to be received from the current interface.
This has some side effects. When for example an NFS is mounted when
one interface is active and the interface is changed afterwards the
NFS packets leave the new interface, but the NFS server won't be
reachable there.
Instead of changing the whole network traffic to the current ethernet
interface we now initialize a network connection with the current
network interface, but then the connection will continue to use that
interface even when the current interface is changed.

Checksum calculation on data including its own checksum (as is the case with
IP headers) should give 0xffff before bit flipping. Current code works well
for the correct checksum case, but fails to identify errors.

Rather than storing the parameters globally and trying to keep them
in sync with the device parameters, store the parameters in the ethernet
device directly. Also, update to dev_add_param_ip().

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

Reduce confusion by making clear six bytes are passed,
not a string.

'nameserver' and 'domainname' should be globally available variables
specific to networking. Register a 'net' device to store these variables.

Introduce getenv_ip_dns to be able to do not do the resolv when using it in
resolv for the nameserver (Do not loop).

This is not yet used, but with this the different network
commands can get rid of their global data.

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.
xmalloc(), xmemalign() always return non-NULL or panic().

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.

Instead of having a big switch/case for every protocol, do
the right things in the individual functions before callong
NetLoop().
