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

Tests for wire protocol version 2 exchange.
Tests in this file should be folded into existing tests once protocol
v2 has enough features that it can be enabled via #testcase in existing
tests.
