[PATCH V2 0/6] introduce basic facilities for virito live migration

[Zhu Lingshan <lingshan.zhu@intel.com>]

This series introduces basic facilities to support
virtio live migration, includes:

1)a new SUSPEND bit in the device status
Which is used to suspend the device, so that the device states
and virtqueue states are stabilized.

2)virtqueue state and its accessor, to get and set last_avail_idx
and last_used_idx of virtqueues.

3)dirty page tracking

Changes from V1:
1)move vq state defination from content.tex to splited/packed.tex(Michael)
2)"the device should ignore resetting vqs when suspended" ==> "the driver should not reset vqs when suspended"(Michael)
3)add dirty page tracking facility
