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.

Structure of a session:


session {
	-- properties --
	conn -- the tcp connection
	notopen -- true if stream has not been initiated, removed after receiving <stream:steam>
	type -- the connection type. Valid values include:
			-- "c2s_unauthed" - connection has not been authenticated yet
			-- "c2s" - from a local client to the server
	username -- the node part of the client's jid (not defined before auth)
	host -- the host part of the client's jid (not defined before stream initiation)
	resource -- the resource part of the client's full jid (not defined before resource binding)
	full_jid -- convenience for the above 3 as string in username@host/resource form (not defined before resource binding)
	priority -- the resource priority, default: 0
	presence -- the last non-directed presence with no type attribute. initially nil. reset to nil on unavailable presence.
	interested -- true if the resource requested the roster. Interested resources receive roster updates. Initially nil.
	roster -- the user's roster. Loaded as soon as the resource is bound (session becomes a connected resource).
	
	-- methods --
	send(x) -- converts x to a string, and writes it to the connection
	close(x) -- Disconnect the user and clean up the session, best call sessionmanager.destroy_session() instead of this in most cases
}

if session.full_jid (also session.roster and session.resource) then this is a "connected resource"
if session.presence then this is an "available resource" (all available resources are connected resources)
if session.interested then this is an "interested resource" (all interested resources are connected resources)
