(encode_invocation_designation): Use macro

CODING_SPEC_ISO_NO_REQUESTED_DESIGNATION.
(encode_designation_at_bol, setup_coding_system): Likewise.
Fset_terminal_coding_system_internal): Renamed from
Fset_terminal_coding_system.  Make it non-interactive.  Do not
call Fredraw_display ().
(Fset_keyboard_coding_system_internal): Renamed from
Fset_keyboard_coding_system.  Make it non-interactive.
