Modify the decoder AV1_SET_REFERENCE API

Modified the decoder AV1_SET_REFERENCE API so that it allowed to set a
reference frame by copying the buffer poniters instead of copying the
whole frame data.

Use use_external_refernce_buffers flag to identify whether y_buffer,
u_buffer, and v_buffer points to the internally allocated memory or
external buffers, so that these buffer pointers are restored after
the usage of external refernce buffers.

Modified the example code to use the modified API.
