Merge of r4886, r4887, r4894: log variables generalization: *) Log: $apache_bytes_sent removed. It was renamed to $body_bytes_sent in nginx 0.3.10 and the old name is deprecated since then. *) Variable $bytes_sent. It replicates variable $bytes_sent as previously available in log module only. Patch by Benjamin Grössing (with minor changes). *) Variables $connection and $connection_requests. Log module counterparts are removed as they aren't used often and there is no need to preserve them for efficiency.
