d7d950e8bd [libpng16] chore: Clean up the leading blank lines from all source files
The leading blank lines are apparently an artefact of an older source
control system.  They are not required and they look like accidents,
because starting a source file with a blank line is not a regular habit
of software developers nowadays.

This is a cherry-pick of commit 37cc20add8fb5b83bb5299a26cd3b41e0f776017
from branch 'libpng18'.

cd5e582fd6 Revert "oss-fuzz: Transfer to an external repo and remove from this repo"
This reverts commit b7276eca0182bb6ad174ef044bb5f6f0504451af.

Although the brand new pngfuzz repo is coming up next, it turned out
that the deletion of contrib/oss-fuzz/ from the 'libpng16' branch was
premature. (Oopsie!)

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.
