8372534: Update Libpng to 1.6.51

[gnu-andrew]

Update to the latest version of libpng. Change includes both the backport of the latest libpng change, JDK-8372534, and previous updates not present in 8u (JDK-8316030 - 1.6.40, JDK-8329004 - 1.6.43, JDK-8348598 - 1.6.47). The change built fine with GCC 8 on RHEL 8 and java/awt/SplashScreen tests passed.

I also included UPDATING.txt introduced in JDK-8208353 in 11u, but not 8u, and updated in JDK-8295685 as part of the JDK-8329004 backport which updates it.

I'm proposing this during rampdown so the release ships with the latest version, as we also do with e.g. tzdata.

Thank you for the backport.
I'm not a reviewer, but it looks good to me. I do not see any regressions.

Thanks Alexey. I'll have to move this over to 8u-dev now as we are post-freeze, but still plan to include this in the January release in sync with the later JDK releases.
