For net boot setups it is useful to submit boot params like server or
bootfile over dhcp. To distinguish diffrent type of OS running on the same hardware,
a custom vendor id can be sent in dhcp discover/request messages.
E.g. the ISC dhcp server can be configured with
| option client-uuid code 97 = { unsigned integer 8, string };
| class "at91sam9x5ek" {
| match if substring (option vendor-class-identifier,0,20) = "barebox-at91sam9x5ek";

We register a device in eth_register, thus we have to unregister it in
eth_unregister. Also, if the device we unregister is the current device,
we have to set the current eth_device to NULL so that it isn't used anymore.

On my laptop with avahi enabled (linux mdns implementation), the unmount
take quite long, because the avahi daemon tries to resolve the client's
host name. This leads to a delay of about 8 seconds of the unmount reply
messages, so that barebox runs into a timeout. This patch increases the
NFS timeout to 15 to work around the problem.

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().

When retrieving the MAC address from EEPROM, we must notify the networking core
at eth registration time. Otherwise we get the 'No MAC address set' warning on
the first network access, and the MAC address is set to a random value instead
of the real one.

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 writing the MAC address into the hardware on device open time
write it to the hardware when the user changes the parameter. This
way a user can change the MAC address in the hardware without actually
using the device. This helps Linux Network drivers which expect a valid
MAC address on startup.
