vpSetClientData - define a client data pointer

vpc    VolPack context from vpCreateContext.client_data
              Pointer to application-specific client data.

vpSetClientData  is  used  to store a pointer to application-specific client data in the VolPack context.
       This pointer is passed to some of the callback routines (see vpSetCallback(3)) to allow  the  application
       to define its own state variables.  The pointer is not used by VolPack.

       The return value is always VP_OK.
