f4d2421 by Guy Harris (guy@xxxxxxxxxxxx):

    Add a routine to check whether all bytes implied by a 64-bit length exist.
    
    This lets us blow up with oversized 64-bit length values, before casting
    them to the 31-bit lengths we can actually handle in Wireshark, rather
    than blindly casting them with weird results.
    
    Use that in the MySQL dissector, and, if we get past the test, cast the
    lengths to int to squelch warnings.
