frame_size is the number of bytes left in the packet, so if we are passing

Try to set AVFrame.reference to correct values.

I am not sure these new values are correct, not am I sure
the semantics are a good idea since we do not seem to make any
use of them but they caused a lot of confusion, but this
seems to make things closer to matching the documentation.

This is required specifically for setting frame->format to -1,

4xm: use reget_buffer() in decode_frame()
...
Also remove unnecessary call to avctx->release_buffer(). reget_buffer
is required since apparently the codec needs to be feeded with the
previous frame data.
Releasing the frame and using get_buffer was working only in the case
get_buffer() was returning the old frame data, and resulting in
playback artifacts otherwise.
Fix trac issue #85 .
