2020-11-27rename to libvfio-user (#128)John Levon6-177/+178
The muser name no longer reflects the implementation, and will just serve to confuse. Bite the bullet now, and rename ourselves to reflect the actual implementation.

2020-10-29support for live migration region and dirty page loggingThanos Makatos2-61/+214
This patch adds support for the live migration region and dirty page logging following VFIO. Live migration is NOT yet functional as handling accesses to the migration region is not yet implemented. Currenty the live migration region is fixed at index 9 simply for simplifying the implementation. Dirty page logging is simplified by requiring IOVA ranges to match exactly the entire IOVA range.
