block/block-copy: block_copy(): add timeout_ns parameter
Add possibility to limit block_copy() call in time. To be used in the
next commit.
As timed-out block_copy() call will continue in background anyway (we
can't immediately cancel IO operation), it's important also give user a
possibility to pass a callback, to do some additional actions on
block-copy call finish.
