More patches

[Sascha Hauer]

Hi all,

Here are some more patches, most notably the the possibility to merge
the default environment together from different directories. We can then
introduce a generic default environment which can be used from multiple
boards. Each board can make specific additions to this default environment.

Also, maybe this is controversal, the network stack now generates a random
MAC address if now valid address is found.
