Implement the virtio-iommu driver, following specification v0.9 [1].

Only minor changes since v5 [2]. I fixed issues reported by Michael and
added tags from Eric and Bharat. Thanks!

You can find Linux driver and kvmtool device on v0.9 branches [3],
module and x86 support on virtio-iommu/devel. Also tested with Eric's
QEMU device [4].
