Add feature flag allowing guest kernel to run in domain 0.

To support this we give kernel GDT entries DPL=0 and use kernel
segment selectors with RPL=0. Xen will crunch these to ring 1 when
they are passed in. When a segment selector is used directly or placed
in a stack frame the guest OS is reponsible for crunching the RPL.
