SERVER-24418 Make Message and BufBuilder use SharedBuffer for memory management
This makes it possible to get owned BSONObj out of a Message without copying.
Hooked up to the following places:
- Anything using the Fetcher (including oplog fetching on secondaries)
- Anything using DBClientInterface::findOne()
- Anything using CursorResponse (including Sharded queries)
As a simplification, Messages no longer support non-contiguous buffers, or
non-owning buffers. The former wasn't used by anything, and the latter was
only used by mongosniff only for messages that fit in a single packet.
