[PATCHv4 0/6] qemu-kvm: vhost net support

["Michael S. Tsirkin" <mst@redhat.com>]

This adds support for vhost-net virtio kernel backend.

This is not intented for merge.  See vhost net patch description for
details.  This applies on top of commit
47e465f031fc43c53ea8f08fa55cc3482c6435c8 in Avi's tree.  It won't apply
to tree tip. TODO: rebase.

The patchset also includes raw socket backend since I find it useful for
testing vhost. When we get to merging, there's no reason to merge these
features together, and dependency between patches is minimal.

Changes since v3:
- changed option syntax
- filled in feature negotiation
Changes since v2:
- minor fixes
- added patch to build on RHEL5.3
Changes since v1:
- rebased on top of 9dc275d9d660fe1cd64d36102d600885f9fdb88a
