Three more: in qobject-input-visitor.c's
qobject_input_type_number_keyval(), cutil.c's do_strtosz(), and
json-parser.c's parse_literal().
The latter doesn't check for errors since the lexer ensures the input is
sane. Overflow can still happen, and is silently ignored. Feel free
not to convert this one.
