mirror change of -lrumpcrypto ==> -lrumpkern_crypto
rumpusbhc is now ugenhc
The rumpdev_net80211 until-recently-wip component is now rumpnet_net80211.
WARNS + make compile
Add an example program which shows how to do "ifconfig rum0 up".What makes this special is that the USB driver stack, the rumdriver, network subroutines and net80211 are running in userspacein a rump kernel instead of in the host kernel.
