Wang Xiaoguang dda3245eca btrfs: expand cow_file_range() to support in-band dedup and subpage-blocksize
Extract cow_file_range() new parameters for both in-band dedupe and
subpage sector size patchset.

This should make conflict of both patchset to minimal, and reduce the
effort needed to rebase them.
