- Use the new trace log facilities for debug logging. - In store_body(), only allocate fd:s on the connection pool when the   pool of the in brigade differs from the request pool. This avoids   accumulating fd:s on a connection when doing keepalive in most cases,   and also avoids the weird Bad File Descriptor error in the corner case.
