- context (and other variables) passing between C-C. Can now passed by value.
- removed unnecessary Fortran C-interface; trailing underscore in C-function no longer necessary
- renamed C-function and Fortran-interface to C-function from qmckl_sherman_morrison_c_/qmckl_sherman_morrison to qmckl_sherman_morrison/qmckl_sherman_morrison
- removed unneccesary artificial pointer variables in qmckl_sherman_morrison and pass them by value.
