eliminate WHO arguments from interpreter-private functions
* interpreter-private.h, inpterpreter-private.cc (__get_interpreter__,
__get_dynamic_loader__, __get_error_system__, __get_gh_manager__,
__get_help_system__, __get_input_system__, __get_load_path__,
__get_load_save_system__, __get_event_manager__,
__get_output_system__, __get_type_info__, __get_symbol_table__,
__get_current_scope__, __require_current_scope__, __get_evaluator__,
__get_bp_table__, __get_child_list__, __get_cdef_manager__,
__get_display_info__, __get_gtk_manager__): Eliminate WHO argument.
Previously, it was never displayed by __get_interpreter__. And, as
pointed out by Petter Tomner in patch #10216, passing a std::string
object could have performance issues.
(__get_interpreter__): Eliminate useless call to error. Display
message to std::cerr then abort.
