wireprotov2: update stream encoding specification...

wireprotov2: update stream encoding specification The encoding of data within streams in the frame-based protocol is not yet defined or implemented. This means that all data in wire protocol version 2 is currently being sent out raw, without compression. That's obviously not ideal. This commit formalizes the beginnings of stream encoding support in the protocol. I suspect we'll change behavior substantially in the future. My goal is to get something landed so we can use compression. We can build out more robust support later. Because the frame type ID changed, this is strictly BC. But existing code wasn't using the frame. I'll bump the framing protocol version later once code is introduced to use the new frame. Differential Revision: https://phab.mercurial-scm.org/D4915
