[PATCH v3 00/10] Further bitmaps improvements

[Vladimir Sementsov-Ogievskiy]

Hi!

The main feature here is improvement of _next_dirty_area API, which I'm
going to use then for backup / block-copy.

v3: rebase on current master. Mirror don't use _next_dirty_area any
more, so mirror chunks dropped (patches 05 and 07) and 07 commit message
changed.

Vladimir Sementsov-Ogievskiy (10):
  hbitmap: assert that we don't create bitmap larger than INT64_MAX
  hbitmap: move hbitmap_iter_next_word to hbitmap.c
  hbitmap: unpublish hbitmap_iter_skip_words
  hbitmap: drop meta bitmaps as they are unused
  block/dirty-bitmap: switch _next_dirty_area and _next_zero to int64_t
  block/dirty-bitmap: add _next_dirty API
  block/dirty-bitmap: improve _next_dirty_area API
  nbd/server: introduce NBDExtentArray
  nbd/server: use bdrv_dirty_bitmap_next_dirty_area
  block/qcow2-bitmap: use bdrv_dirty_bitmap_next_dirty
