block/block-copy: use aio-task-pool API

Run block_copy iterations in parallel in aio tasks.

Changes:
  - BlockCopyTask becomes aio task structure. Add zeroes field to pass
    it to block_copy_do_copy
  - add call state - it's a state of one call of block_copy(), shared
    between parallel tasks. For now used only to keep information about
    first error: is it read or not.
  - convert block_copy_dirty_clusters to aio-task loop.
