Add a helper function for fetching max cpus supported by kvm.
Make QEMU exit with an error message if smp_cpus exceeds limit
of VCPU count retrieved by invoking this helper function.

Hi folks,

This patchset adds vhost-blk support. vhost-blk is a in kernel virito-blk

Start with a clean slate, a virtio-blk device that supports virtio

The I/O is going to happen in a separate optimized data plane thread.
