PVODE library doesn't compile on Cray XT-5

[bendudson]

Can't compile PVODE on HECToR: Makefile uses $(CC) to compile, but include file llnltyps.h contains a namespace statement.

[bendudson]

To fix:

In Makefile:

BOUT_TOP = ../../.. include $(BOUT_TOP)/make.config

change $(CC) to $(CXX)

Insert "mpi.h" as the FIRST include (otherwise SEEK_SET defined) in cvode.c, nvector.c , cvspgmr.c, cvdiag.c

Add newlines to the end of cvode.h, llnlmath.c, cvspgmr.h, smalldense.c

[bendudson]

Same changes needed in precon/Makefile

"mpi.h" also needed at top of pvbbdpre.c, band.c

PVODE library in repository (for now) with changes so compiles
