This is version 2 of the modern virtio support for kvmtool.

Since v1 [1]:
* Repaired vhost-net for pci-modern, by adding patches 4 and 5
* Added patch 6 that extends the feature fields and simplifies modern
  features handling
* Added patch 12, a small cleanup

Since vsock and scsi devices have been broken for a while, this series
doesn't attempt to make them work but I have another series [2] to fix
the vhost support, that I will send later.
