Several improvements in the parsing of UDP/Hello packets.
* Fix check of the packet's size and the "PDU Length" field;
* Add check for the "Message Length" field;
* Check for invalid labelspace earlier.
* Use if_lookup() on disc_recv_iface() to reduce one level of identation;
Additionally, add the following safeguards:
* Check for unicast link hellos;
* Check for multicast targeted hellos;
* Validate packet's source address;
* Validate received transport-address.
Put the ancillary function bad_ip_addr() into a new file, util.c, which
will be used later for several other things.
