e406703 by Guy Harris (guy@xxxxxxxxxxxx):

    Fix handling of the byte order magic number.
    
    Just treat it as an array of bytes.  When checking for whether it's a
    pcapng file, also determine whether it's big-endian or little-endian.
    Note that reading it in *host* byte order will tell you whether it's in
    your byte order or byte-swapped; you have to know your byte order to
    know whether that means little-endian or big-endian.
    
    Have a #define for the byte-order magic number size, as all byte order
    magic number values must be that size, and use that as the size of the
    magic-number arrays.
    
    Also use a #define for the SHB block type magic number.
    
    Get rid of a now-unused expert info.  (If the magic number isn't
    something we recognize, we don't treat the file as a pcap file, so it
    can never be "unknown".)
