This will avoid some differences when checking in different time zones.
We now run the tests without the '-t' option. This will allow to get
problems/changes in time printing functions.
Update the output of the tests accordingly.
Moreover:
Add the '-#' option to better identify a packet when there is a difference
in output.
hncp_print_rec() validates each HNCP TLV to be within the declared as
well as the on-the-wire packet space. However, dhcpv6_print() in the same
file didn't do the same for the DHCPv6 options within the HNCP
DHCPv6-Data TLV value, which could cause an out-of-bounds read when
decoding an invalid packet. Add missing checks to dhcpv6_print().
This fixes a buffer over-read discovered by Bhargava Shastry,
SecT/TU Berlin.
Add a test using the capture file supplied by the reporter(s).
