    Do proper input validation to fix for CVE-2011-2895.
    
    It ensures that all valid input can be decompressed, checks that the
    overflow conditions doesn't happen and generally tightens the
    validation of the LZW stream and doesn't pessimize the inner loop for
    no good reason. It's derived from a change in libarchive from 2004.
