pmdaSendError - send an error PDU to PMCD

       As  part  of the Performance Metrics Domain Agent (PMDA) API (see PMDA(3)), this routine allows a PMDA to
       send an error PDU to PMCD.  There is presently only one use for this - so the PMDA can inform  PMCD  that
       it is ready (or not ready) to process requests.

       The protocol details are described in pmcd(1) and PMDA(3), but basically if a PMDA starts in the notready
       state  (as  may be specified in pmcd.conf, see pmcd(1)) then PMCD will not send it any requests until the
       PMDA sends an PM_ERR_PMDAREADY error PDU using this function.  This is used by a PMDA  that  may  have  a
       long startup time, e.g. to process a large configuration file or similar.
