developer-guidelines.sgml: Allow special value "U"
Allow a literal "U" to be specified in place of an actual value within the performance data string. An "U" corresponds to RRDtool's "UNKNOWN" value; i.e., it's meant to indicate that data acquisition failed for some reason. PNP4Nagios already supports this extension.
