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.
