scroggo 3965825b97 Check libpng directly into third_party/
With this change, the CMake build, which does not use DEPS to sync
external projects, is able to build and use the same version of libpng
that is used in other builds.

This will allow all platforms (including Google3 CMake build) to test on
the same version of libpng, so we do not need to make SkPngCodec support
all versions of libpng.

- Update CMakeLists.txt to use the checked in libpng.
- Check in libpng version 1.6.22rc01
- Update README.google
- Replace our old LICENSE file with the latest one from libpng

This "contrib" directory contains contributions which are not necessarily under
the libpng license, although all are open source.  They are not part of
libpng proper and are not used for building the library, although some are used
for testing the library via "make check".
