John Bowler 5d56786eff [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.
