protocol: introduce protocol extension mechanisms
Create protocol.{c,h} and provide functions which future servers and clients can use to determine which protocol to use or is being used. Also introduce the 'GIT_PROTOCOL' environment variable which will be used to communicate a colon separated list of keys with optional values to a server. Unknown keys and values must be tolerated. This mechanism is used to communicate which version of the wire protocol a client would like to use with a server.
