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.
