[libvirt] [PATCH RFC] Add support for QEMU vhost-user feature

Howdy! This patch adds support for the QEMU vhost-user feature to Libvirt. vhost-user is an efficient interface between guests and userspace network stacks (vswitches). Our goal is to have vhost-user supported in the OpenStack Juno release. We hope it is okay to start code review on qemu, Libvirt, and OpenStack in parallel. We understand that code will have to be merged first into QEMU and then into Libvirt and then into OpenStack.
