#153: linearsolverloader pardiso interface out of date

 PARDISO has a new interface (as of v4.0.0?) that contains additional
 arguments to the old interface.

 The HAVE_PARDISO_NEWINTERFACE macro is used to establish this existence at
 compile time if --have-pardiso= is used at configure. Otherwise the old
 interface is assumed.

 Further, the linear solver library loader interface still uses the old
 version.

 Looking at Ipopt/configure.ac it seems that the new interface can be
 differentiated from the old one as defines the symbol
 pardiso_ipopt_newinterface. This could be exploited by the linear solver
 loader to use the correct interface.

 I suspect that the new interface should be made the default in
 IpPardisoSolverInterface and the logic inverted so that ONLY if the old
 interface is detected at configure time does IpPardisoSolverInterface use
 the old interface. This then allows linear solver loader to detect the old
 interface at runtime and just ignore the additional arguments (note: I
 have not checked if this can be done safely).

 Jonathan.
