wireprotoserver: add version to HTTP protocol name (API) This matches what we did for the SSH protocol handler in ac33dc94e1d5. .. api:: HTTP protocol handlers now advertises its internal name as ``http-v1`` instead of ``http``. Differential Revision: https://phab.mercurial-scm.org/D2219

httppeer: remove httpspeer All it did was verify at construction time that Mercurial supports TLS. instance() is what's used to construct peer instances. So we can just inline this check into that function and do away with the type variant. Differential Revision: https://phab.mercurial-scm.org/D2216

httppeer: remove redundant code to fetch capabilities _fetchcaps() is called by httppeer.instance(), which is the only instantiator of httppeer. Since _fetchcaps() always sets self._caps and since 197d10e157ce removed the fallback for cases where the remote doesn't support capabilities, we can remove some dead code from httppeer.capabilities().

httppeer: change logic around argument handling The code to process arguments only makes sense if there are arguments. So change an "else" to "elif args", remove an "if" that isn't necessary, and add some docs for good measure. Differential Revision: https://phab.mercurial-scm.org/D2214
