Sent again. It seems the previous patch didn't actually apply (I thought
I'd tested applying it to a clean tip, but apparently not).

# HG changeset patch

Move Linux-specific privcmd code into private libxc implementations.
Make header path for kernel's privcmd/evtchn headers generic.
Remove pointless xi_*() interface that was using private libxc
interfaces.
