This is not yet used, but with this the different network

Krzysztof Halasa c5baa0edc4 Fix error handling with malloc, memalign etc. Introduce xmemalign(). 
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().

Sascha Hauer 57e1fc33bd net: remove old network stack

Sascha Hauer 97070487fa net: Implement a new network stack 
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.

Sascha Hauer 994f95c073 net: remove need for eth_halt/eth_open 
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.
