wireprotoserver: remove support for do_<command> handlers (API) Old versions of wire protocol handlers relied on methods named do_<command> to handle wire protocol commands. The last definition of these methods on sshserver was removed by 9f6e0e7ef828 ~2 years ago. I think it's time to not support this mechanism for defining command handlers. .. api:: sshserver no longers looks for wire protocol command handlers in methods named do_<command>. Use @wireproto.wireprotocommand to declare wire protocol command handler functions. Differential Revision: https://phab.mercurial-scm.org/D1985

wireprotoserver: make attributes private These aren't part of the protocol interface. So they should be _ prefixed. Differential Revision: https://phab.mercurial-scm.org/D1984

wireprotoserver: remove unused response attribute I think the last use of this attribute was removed by 2f8adc60e013 in 2010. Differential Revision: https://phab.mercurial-scm.org/D1983
