[libpng16] Revised png_set_keep_unknown_chunks() so num_chunks < 0 means
ignore all unknown chunks and all known chunks except for IHDR, PLTE, tRNS, IDAT, and IEND. Previously it only meant ignore all unknown chunks, the same as num_chunks == 0. Revised png_image_skip_unused_chunks() to provide a list of chunks to be processed instead of a list of chunks to ignore. Revised contrib/gregbook/readpng2.c accordingly.
