conf: Safer parsing of MAC addresses
In conf() we parse a MAC address in two places, for the --ns-mac-addr and the -M options. As well as duplicating code, the logic for this parsing has several bugs: * The most serious is that if the given string is shorter than a MAC address should be, we'll access past the end of it. * We don't check the endptr supplied by strtol() which means we could ignore certain erroneous contents * We never check the separator characters between each octet * We ignore certain sorts of garbage that follow the MAC address Correct all these bugs in a new parse_mac() helper.
