[Qemu-block] [PATCH 0/8] backup improvements

Hi all!

There are some fixes and refactorings I need on my way to resend
my backup-top series. It's obvious now that I need to share copying
code between backup and backup-top, as backup copying code becomes
smarter and more complicated. So the goal of the series is to make copying
code more share-able.

It's based on John's bitmaps branch, rebased on master.

Vladimir Sementsov-Ogievskiy (8):
  block/backup: deal with zero detection
  block/backup: refactor write_flags
  block/io: handle alignment and max_transfer for copy_range
  block/backup: improve unallocated clusters skipping
  block/backup: fix backup_cow_with_offload for last cluster
  block/backup: teach backup_cow_with_bounce_buffer to copy more at once
  block/backup: merge duplicated logic into backup_do_cow
  block/backup: backup_do_cow: use bdrv_dirty_bitmap_next_dirty_area
