This patch updates the virtio device methods to provide hooks for setting and
getting the config. This is needed for ballooning since the balloon driver
uses config changes to signal changes in the balloon amount. We also add a
method to signal that we have changed the config.

This patch adds a kvm_has_mmu_notifiers routine to libkvm. This allows
userspace to query the existence of mmu notifiers which is important for
ballooning since madvise() is not safe from userspace without it.
