Original commit message from CVS: * gst/gstbuffer.c: (_gst_buffer_copy), (gst_buffer_create_sub): * tests/check/gst/gstbuffer.c: (GST_START_TEST), (gst_buffer_suite): No point in checking if the size of the subbuffer > 0, the code handles it correclty as demonstrated by unit test. Also add a unit test for the zero sized _new_and_alloc and _copy. Fixes #346663.
