8cfdb5436d Clean up oss-fuzz 
With the caveat that oss-fuzz needs a full sync with upstream, here
are the changes applied to our old copy:
 * Add a missing #include directive.
 * Remove the "last changed" version info.
 * Clean up the trailing whitespace.

301f7a1429 oss-fuzz: Add custom malloc with max limit to prevent OOM 
This adds the custom malloc/free functions from the old
libpng_read_fuzzer to the upstream fuzzer to prevent clusterfuzz
running into OOM.

a74aa9a002 [libpng16] Replace the remaining uses of png_size_t with size_t 
In v1.6.0, size_t became a required type. It should be used
consistently. To maintain backwards compatibility, png_size_t
is still maintained in deprecated form.
