    pcapng (dissector): don't assume the endianness doesn't change.
    
    Keep the endianness (as an ENC_ value) in the info structure we use
    while dissecting.
    
    When dissecting an SPB, peek ahead at the byte-order magic before
    dissecting the block length, to determine the byte order of all fields
    in that block *and* all other blocks in that section.  Report an error
    and stop dissecting if the byte-order magic isn't valid.
