block/dirty-bitmap: add _next_dirty API
We have bdrv_dirty_bitmap_next_zero, let's add corresponding bdrv_dirty_bitmap_next_dirty, which is more comfortable to use than bitmap iterators in some cases. For test modify test_hbitmap_next_zero_check_range to check both next_zero and next_dirty and add some new checks.
