internals: extract wire protocol version 2 commands to standalone doc
wireprotocol.txt is a bit long and unwieldy. I think splitting it up
will help aid comprehension.
Let's start by extracting wire protocol version 2 commands to a
standalone document.
As part of the port, I munged with the section titles a bit and
expanded the TODO around node namespaces.
