For the generic frontend server, the maximum record size is used as maximum
size of incoming packages (SRU + Z39.50). The value until was previously
only used in Z39.50 Init negotiation and, later, in a session controlled
sizes of records returned. This is controlled using -k option. It can be
specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
