pack.c: avoid signed integer overflowwip-topic/pack-integer-overflow
* pack.c (pack_pack, pack_unpack): Use strtol() instead of strtoul(), as
the length must be in the range of long. This suppresses the implicit
type conversion and let it raise a better exception for too large
length.
* pack.c (pack_unpack): Fix 'b', 'B', 'h', 'H', 'u', 'm' format. Ensure
that multiplying does not cause integer overflow.
