The packet length must be <= MAXIMUM_SNAPLEN. Currently, there is no D-Bus printer, thus no need for a bigger length. Now a pachet is valid if: capture length != 0, packet length != 0, capture length <= MAXIMUM_SNAPLEN, packet length <= MAXIMUM_SNAPLEN, packet length >= capture length. Moreover: Fix the packet header lengths of some fuzzed pcap files: If the lengths are > MAXIMUM_SNAPLEN, set them to MAXIMUM_SNAPLEN. Thus they will be always usable with this new sanity check.
