mod_s2s: Vary log level by remote stream error
Increases log level for stream conditions that could indicate a problem on our end, especially programming errors like invalid XML, or the remote server saying that our certificate is invalid, since these should be investigated. Non-issues like closing of idle streams are lowered to debug since it's mostly noise. Other issues left at info are mostly about changes to the remote server, e.g. complete or partial shutdown.
