Added Reverse-Cuthill-McKee reordering into INNER_MPTILUC preconditioner
as default reordering when Metis_NodeND is not provided. On the tests
RCM shows 10% more fill-in in inverse factors then with Metis_NodeND,
but the RCM reordering procedure is 4 times faster then Metis_NodeND and
overall computational time decreases with RCM.
