Content distribution via CoralCDN

[Nick Johnson]

We're experimenting with using CoralCDN (http://www.coralcdn.org/) for
distributing kernels and other boot files. Hopefully the improved
latency should improve download speeds for users around the world.

Please let us know how effectively this works for you - or even if it
degrade performance - on the official group at
