[libpng16] Implemented 'restrict' for png_info and png_struct. Added new "png_structrp" typedef. Because of the way libpng works both png_info and png_struct are always accessed via a single pointer. This means adding C99 'restrict' to the pointer gives the compiler some opportunity to optimize the code. This change allows that.
