V1-->V2
* expose the counter that logs the times of updating the dirty bitmap to end
user.
a. Optimization the xbzrle remarkable decrease the cache misses.
The efficiency of compress increases more than fifty times.
Before the patch set, the cache almost totally miss when the
number of cache item less than the dirty page number. Now the
hot pages in the cache will not be replaced by other pages.
b. Reducing the data copy
c. Fix two corruption issues.
