Parameterize Julienne's multi-image support to allow expansion to other SPMD multi-process models beyond Fortran's built-in SPMD features. Now when HAVE_MULTI_IMAGE_SUPPORT is enabled and JULIENNE_PARALLEL_CALLBACKS is defined, Julienne will no longer directly invoke the Fortran multi-image features. Instead it will invoke client-provided procedure pointer callbacks that implement the necessary features. This allows the client to swap in another SPMD multi-process interface, for example PRIF or MPI. Fixes issue BerkeleyLab#57
Also tweak ifx to provide better crash output
