    zbxpcp: add derived metrics support
    
    Turns out adding derived metrics support to zbxpcp is trivial.
    
    Based on comments from Ken I think we can ignore errors from
    pmLoadDerivedMetrics, if the configuration file is malformed
    then messages will be logged into the zabbix-agent log file.
    
    Update the man page accordingly.  A small CodingStyle fixlet
    included as a bonus as well.
