The checks for reserved names are spread far and wide.  Move one from
add_name() to new check_defn_name_str().  This is a first step towards
collecting them all in dedicated name checking functions next to
check_name().

While there, drop the quotes around the meta-type in
check_name_str()'s error messages: "'command' uses ... name 'NAME'"
becomes "command uses ... name 'NAME'".
