Dag-Erling Smørgrav 82835638e1 Tweak the way we determine if an interface needs to have its name translated. 
Add some missing break statements in the socket ioctl switch.
Check the return value from copyin() / copyout().
Fix some disorderings and misindentations.
Support a couple more socket ioctls.
Add missing break statements.
