protocol: add the abilty to trace the protocol between the client and server This is useful when debugging issues with driving hg via hglib where output and error messages can be lost. Call setprotocoltrace with the name of a trace function or None. If the trace function is None no tracing is done. The trace function is called with the direction, the channel-identified and its data.
