Continue the move of existing Documentation/technical/* protocol and file-format documentation into our main documentation space. By moving the things that discuss the protocol we can properly link from e.g. lsrefs.unborn and protocol.version documentation to a manpage we build by default. So far we have been using the "gitformat-" prefix for the documentation we've been moving over from Documentation/technical/*, but for protocol documentation let's use "gitprotocol-*".
