Decoder relies on previous frame data, so use reget_buffer().
This also set frame->reference to 3, as the frame will be requested
unmodified later so it shouldn't be modified by the application.
Fix playback of file Clock.avi.

The release_buffer was cleaning the provided frame, thus causing the
successive call to avctx->reget_buffer() to allocate a new frame. In
case the returned frame was not the same one previously returned but a
new one with different data, it resulted in artifacts.

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.

Store palette data in the codec context, do not assume that the frame
allocated the first time by avctx->get_buffer will be returned again.
This requires to store the palette which comes with the first frame in
the context, and copy it to the following frames.

Also deprecate av_get_pict_type_char() in favor of
av_get_picture_type_char().
The new enum and av_get_picture_type_char() are defined in libavutil.
This allows the use in libavfilter without the need to link against
libavcodec.

The CrystalHD hardware can do scaling, which is particularly
desirable when dealing with some high resolution clips that take
so long to decode and copy out that they end up playing back
slower than realtime. By using scaling, we can make the output
frames smaller and reduce the copy out time.
This option takes the desired horizontal width in pixels, and
the hardware will do an aspect-scale. Upscaling is not supported
and the hardware will simply ignore any request to do so.
