wireprotoserver: rename hgweb.protocol to wireprotoserver (API) The HTTP wire protocol server / response handler is currently defined in the hgweb sub-package. That only kind of makes sense. hgweb does contain most of the HTTP server code. However, hgweb is more tailored for providing HTTP server and WSGI scaffolding and serving hgweb requests. The wire protocol is kind of its own beast. In addition, the code for HTTP and SSH wire protocol handling is actually pretty small and it needs to stay in sync to ensure parity between the transport implementations. We rename mercurial/hgweb/protocol.py to mercurial/wireprotoserver.py. The new module will eventually become the home of the SSH handler as well. .. api:: Content from mercurial.hgweb.protocol has been moved to mercurial.wireprotoserver.
