Remove arc4random() and arc4randbytes() from the kernel API. Replace
arc4random() hacks in rump with stubs that call the host arc4random() to
get numbers that are hopefully actually random (arc4random() keyed with
stack junk is not). This should fix some of the currently failing anita
tests -- we should no longer generate duplicate "random" MAC addresses in
the test environment.

fix an uninitialised variable problem. large-ish function, but i
couldn't see how GCC 4.5 isn't wrong about this one.
