py3: use pycompat.bytestr() to convert str into bytes

the keys of opts are str here, so we have to convert it to bytes before passing

Helper function to run protocol tests against multiple protocol versions.
This is easier than using #testcases because managing differences between
protocols with inline conditional output is hard to read.

A no-op connection performs a handshake

>=0.9.1 clients send a "hello" + "between" for the null range as part of handshake.
Server should reply with capabilities and should send "1\n\n" as a successful
reply with empty response to the "between".
