Bridging issues

[nemesisdesign]

Trying different combinations with bridges yelds very strange (and wrong) results.

Generation of bridged interfaces must be improved.

• the whole __find_bridges idea is quite a bad one. It would be better to remove that code altoghether and find a simpler solution.
• bridges should be defined only in /etc/config/network.
• in /etc/config/wireless the attached networks can be defined with a custom attribute, like networks.
• the bridge schema should require the presence of bridge_members

trying to define a bridge interface without specifying "bridge_members" raises this exception:
