Matthew Sakai	b46d79bdb8	dm vdo: add deduplication index storage interface ... This patch adds infrastructure for managing reads and writes to the underlying storage layer for the deduplication index. The deduplication index uses dm-bufio for all of its reads and writes, so part of this infrastructure is managing the various dm-bufio clients required. It also adds the buffered reader and buffered writer abstractions, which simplify reading and writing metadata structures that span several blocks. This patch also includes structures and utilities for encoding and decoding all of the deduplication index metadata, collectively called the index layout.
