Finally, I dropped it altogether. Stephen confirmed for the 
bitstreamBuffers structs are copied locally and ff_draw_horiz_band() will 
always call their draw_slice() with the current_picture, so it's also safe 
to release that in end_frame().

VDPAU is finally the 3rd API not strictly needing that 
hwaccel_priv_close() function so this confirms my intention to drop it.

Besides, I also dropped hwaccel_data, it's not a real gain. I am fine with 
AVFrame.data[3].

New patch attached.
