wireproto: extract HTTP version 2 code to own module
wireprotoserver has generic and version 1 server code. The wireproto
module also has both version 1 and version 2 command implementations.
Upcoming work I want to do will make it difficult for this code to
live in the current locations. Plus, it kind of makes sense for the
version 2 code to live in an isolated module.
This commit copies the HTTPv2 bits from wireprotoserver into a new
module. We do it as a file copy to preserve history. A future
commit will be copying wire protocol commands into this module
as well. But there is little history of that code, so it makes
sense to take history for wireprotoserver.
