    Gst::Buffer: copy_into method now as a static method
    
        * gstreamer/src/buffer.hg: syntax buff1->copy_into(buff2) isn't clear
          for developers. It suggests, that buff1 is copied into buff2.
          Reverse order might be confusing for users, who already knows
          c-style syntax of copying methods, so compromise is here to make
          copy_into method as a static.
        * tests/test-buffer.cc: added tests for copy_into method.
