Hi all. 1. bdrv_dirty_iter_next_area don't use hbitmap_next_zero and uses inefficient loop instead. Let's improve it.
2. bdrv_dirty_iter_next_area don't handle unaligned offset and max_offset correctly. I'm not sure that it is a real bug. But if it is, we need these series in 3.0. Details are in 03 commit message.
