Expose a mechanism to trace block writes
To support live migration without shared storage we need to be able to trace
writes to disk while migrating. This Patch expose dirty block tracking per
device to be polled from upper layer.
Changes from v4:
- Register dirty tracking for each block device.
- Minor coding style issues.
- Block.c will now manage a dirty bitmap per device once
bdrv_set_dirty_tracking() is called. Bitmap is polled by the upper
layer (block-migration.c).
