wireprotoserver: split ssh protocol handler and server We want to formalize the interface for protocol handlers. Today, server functionality (which is domain specific) is interleaved with protocol handling functionality (which conforms to a generic interface) in the sshserver class. This commit splits the ssh protocol handling code out of the sshserver class. Differential Revision: https://phab.mercurial-scm.org/D2080

wireprotoserver: extract SSH response handling functions The lookup/dispatch table was cute. But it isn't needed. Future refactors will benefit from the handlers for individual response types living outside the class. As part of this, I snuck in a change that changes a type compare from str to bytes. This has no effect on Python 2. But it might make Python 3 a bit happier. Differential Revision: https://phab.mercurial-scm.org/D2091
