  vorbisdec: Rename silly "class_" variable to plain "class".
  simple_idct_alpha: Drop some useless casts.
  Simplify av_log_missing_feature().
  ac3enc: remove check for mismatching channels and channel_layout
  If AVCodecContext.channels is 0 and AVCodecContext.channel_layout is non-zero, set channels based on channel_layout.
  If AVCodecContext.channel_layout and AVCodecContext.channels are both non-zero, check to make sure they do not contradict eachother.

  Check AVCodec.supported_samplerates and AVCodec.channel_layouts in avcodec_open().
  aacdec: remove sf_scale and sf_offset.
  aacdec: use a scale of 2 in the LTP MDCT rather than doubling the coefficient table values from the spec.
  Define POW_SF2_ZERO in aac.h and use for ff_aac_pow2sf_tabp[] offsets instead of hardcoding 200 everywhere.
  Large intensity stereo and PNS indices are legal. Clip them instead of erroring out. A magnitude of 100 corresponds to 2^25 so the will most likely result in clipped output anyway.
  qpeg: use reget_buffer() in decode_frame()
  ultimotion: use reget_buffer() in ulti_decode_frame()
  smacker: remove unnecessary call to avctx->release_buffer in decode_frame()
  avparser: don't av_malloc(0).

767848d761 aacdec: remove sf_scale and sf_offset. 
Instead, scalefactors are adjusted by the offset amount, removing the need
for sf_scale, and the MDCT scales are adjusted to compensate for the higher
scalefactors. Floating-point output will be handled by modifying the MDCT
scales.

f4e043ff63 qpeg: use reget_buffer() in decode_frame() 
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.

4f2954e232 smacker: remove unnecessary call to avctx->release_buffer in decode_frame() 
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.

fd37eac495 indeo2: remove unnecessary release_buffer() call 
This was preventing reget_buffer() to return a buffer with the same
data, which was resulting in playback artifacts.

10aa5a6c42 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.
