pmdaPMID - translate a dynamic performance metric name into a PMID

       The  PMDA  must  be  using  PMDA_INTERFACE_4  or  later,  as  specified  in  the  call  to  pmdaDSO(3) or
       pmdaDaemon(3).

       As  part  of  the  Performance  Metrics  Domain  Agent  (PMDA) API (see PMDA(3)), pmdaPMID is the generic
       callback for translating a dynamic metric name into a PMID (pmid).

       Because implementing dynamic performance metrics requires specific PMDA support, and the facility  is  an
       optional  component  of  a  PMDA  (most  PMDAs do not support dynamic performance metrics), pmdaPMID is a
       skeleton implementation that returns PM_ERR_NAME.

       A PMDA that supports dynamic performance metrics will provide a private callback that  replaces  pmdaPMID
       (by assignment to version.four.pmid of the pmdaInterface structure) and implements the translation from a
       dynamic performance metric name into the associated pmid.

pmdaPMID returns PM_ERR_NAME if the name is not recognized or cannot be translated, else returns 0.
