pmaSameInDom - check if two observations of an instance domain are the same`

       This documentation is intended for internal Performance Co-Pilot (PCP) developer use.

       These  interfaces  are  not part of the PCP APIs that are guaranteed to remain fixed across releases, and
       they may not work, or may provide different semantics at some point in the future.

       Checks two observations of the same instance domain are identical.  The code assumes  (a)  old->indom  ==
       new->indom  and  (b)  both  the  instance  domains  are  sorted in ascending internal instance identifier
       sequence; see pmaSortInDom(3) to see how to make the second condition true.

       pmaSameInDom returns 1 if they are the same, returns 0 otherwise.

       The instance domains are considered different if any of the following hold:

       1.  old->numinst != new->numinst

       2.  For some i, old->instlist[i] != new->instlist[i]

       3.  For some i, the strings pointed to by old->namelist[i] and new->instlist[i] are not identical

       For Version 3 archives with "delta indom" support, it is more likely that pmaDeltaInDom(3) is more useful
       than pmaSameInDom, as the former combines the check for two observations of an instance domain being  the
       same with the optional creation of the "delta indom" format if that is the most efficient encoding.
