Andreas Rheinhardt 835d8b7401 avcodec/dvenc: Avoid copying packet data, allow user-supplied buffers ...

When the packet size is known in advance like here, one can avoid
an intermediate buffer for the packet data; this also makes it easy
to allow user-supplied buffers. Only one thing needed to be changed:
The earlier code relied on the buffer having been initially zeroed
by av_fast_padded_malloc(), so one now needs to zero the packet at
first.
