cb1634dd31 block fuzz data over 100kb 
Many codecs can take a huge amount of time attempting to read large
random objects. jpeg_read_header(), for example, can take ~10s on a 1mb
of random data.

Ignore fuzz objects over 100kb.

aac1748615 Explicitly cast to unsigned int before left-shifting 
To avoid potential signed integer overflow (undefined behavior), as
implicit integer promotion means the operand becomes a (signed) int.
