* Add tests for name decoding corner cases * Modify name.decode to throw an error in the following cases: * Not enough data for reading the full label * The label is too long (over 253 characters when dots are included) * A label must be either <= 63 bytes or a pointer * Pointers can only point to prior data (see RFC 1035, section 4.1.4) In addition pointer jumps don't add extra dots in the names anymore. * Make name_decoding tests more specific * Make name.decode non-recursive * Ensure name.decode can read the label header * Fix name.decode error messages
