MINOR: log: provide a function to emit a log for a session
The new function sess_log() only needs a session to emit a log. It will
ignore the parts that depend on the stream. It is usable to emit a log
to report early errors in muxes. These ones will typically mention
"<BADREQ>" for the request and 0 for the HTTP status code.
