- added functions for simplified debugging

- changed functions to pass pointers instead of structs and using realloc
  instead of malloc to reduce memory overhead/usage
- changed functions to return opensc-errors to pass printout-debugging to the
  top level
- included functionality of get_RDR_to_PC_Parameters in
  perform_PC_to_RDR_GetParamters
