Hi all!
v3:
01: drop extra line "+ s->in_flight_bytes -= task->bytes - new_bytes;"
02: add Max's r-b
03: rebased on 01 fix (dropped line not updated now). keep Max's r-b
04: more refactoring:
don't require offset argument of block_copy_task_create being dirty,
use !bdrv_dirty_bitmap_next_dirty_area() in block_copy_task_create()
05: declare block_copy_task_entry (as moving patch dropped)
rebased on 04 changes

block/block-copy: alloc task on each iteration
block/block-copy: add state pointer to BlockCopyTask
block/block-copy: refactor task creation
block/block-copy: use aio-task-pool API
