Rename features->guest_features. This is
what they are, avoid confusion with
host features which we also need to keep around.

Currently we always set the "config space changed" bit to 1 when triggering
any virtio interrupt. While that worked in 2.6.27, newer kernels interpret
that value as "only the config space changed and nothing else happened".
Since we usually trigger interrupts to tell the guest that something did
happen, we just not tell it the config space changed for now until we
implement the correct callback for that.

On S390x we don't want to go through the hassle of emulating real existing
hardware, because we don't need to for running Linux.
So let's instead implement a machine that is 100% based on VirtIO which we
fortunately implement already.
This patch implements the bus that is the groundwork for such an S390x
virtio machine.
