fe815ff587 Add C++ bindings for new_from_memory_steal() 
new_from_memory_steal() will create a new image with the input
buffer and will "move" the data into the image. The buffer is then
managed by the image, and will be freed when it goes out of scope.

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.
