v3:
1. drop the responsive throttle patchset
2. rename background sync to periodic ramblock dirty sync
3. move the cpu-throttle.* from system to migration
4. remove "rs" parameter in migration_bitmap_sync_precopy
5. implement periodic ramblock dirty sync in cpu-throttle.c
6. move the test change into a separate patch

To simplify the cover letter, i have dropped the test data,
please refer to 
https://lore.kernel.org/qemu-devel/cover.1727630000.git.yong.huang@smartx.com/
for more test details.

Thanks Peter and Fabiano for the suggestions and comments.

Please review.

Yong
