- Codegen.mo, for external functions:

  + Previosuly, if the order of outputs are different from the one in the call mapping, it would write the results in the incorrect order.
  + Added testcase for external C functions, where 4 outputs are mapped in different orders.
  + External Java functions use the same mapping as C functions, and do not need testing.
  + Test cases were also added for external FORTRAN 77 functions since the code path for code generation of F77 functions is different. However, the code actually calls the same function as in the C example (the function prototype is identical).
