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.

Coverity found this use after free for task. Please fix.
Oops. Done. Sorry for that :(
