2021-11-01migration/dirtyrate: implement dirty-bitmap dirtyrate calculationHyman Huang(黄勇)1-9/+103
introduce dirty-bitmap mode as the third method of calc-dirty-rate. implement dirty-bitmap dirtyrate calculation, which can be used to measuring dirtyrate in the absence of dirty-ring. introduce "dirty_bitmap:-b" option in hmp calc_dirty_rate to indicate dirty bitmap method should be used for calculation.

2021-11-01migration/dirtyrate: move init step of calculation to main threadHyman Huang(黄勇)1-4/+5
since main thread may "query dirty rate" at any time, it's better to move init step into main thead so that synchronization overhead between "main" and "get_dirtyrate" can be reduced.
