while testing a VP8 encoder I found a mismatch between FFMPEG and libvpx
VP8 decoders. The reason for this mismatch is that FFMPEG doesn't reset
loopfilter delta values at keyframes. Patch that fixes the issue is below.
I've verified that the output of ffmpeg after this patch matches libvpx.

The DPX encoder now writes 12 DPX that open correctly (tested with
ImageMagick), and also correspond to the 12 bit sample files at

Rewrite the DPX decoder to work with provided sample DPXs at
http://samples.ffmpeg.org/image-samples/dpx_samples.zip
The decoder could only decode 8 and 10 bit without alpha correctly,
failing or even crashing at other flavors. This patch aims to fix
these issues, properly decoding all variants of DPX provided in the
referenced DPX sample zip. For 10 and 12 bit, the alpha channel
is ignored, but decoding is still possible.

Some invocations include a verb in the log message, others do not. Yet
av_log_missing_feature expects callers to provide a verb. Change the
function to include a verb instead and update the callers accordingly.
The result is a more natural function API and correct English in the
function invocations.
The vec_splat() intrinsic requires a constant argument for the
element number, and the code relies on the compiler unrolling
the loop to provide this. Manually unrolling the loop avoids
this reliance and works with all compilers.

When decode_nal_units() previously encountered a NAL_END_SEQUENCE,
and there are some junk bytes left in the input buffer, but no start codes,
buf_index gets stuck 3 bytes before the end of the buffer.
This can trigger an infinite loop in the caller code, eg. in
try_decode_trame(), as avcodec_decode_video() then keeps returning zeroes,
with 3 bytes of the input packet still available.
With this change, the remaining bytes are skipped so the whole packet gets
consumed.

I was sadly unable to find a non fuzzed mp3 that uses the
feature that contained the bug (and i searched hard ...), thus
while this fixes the security issue. It may or may not fix
mixed blocks in 8khz mp3s, i cant say due to lack of samples to test.
Security issue exists since: b37d945dd4

This reverts commit d25f87f517.
This breaks decoding of some h264 files
I have tested the original patch with fate but by mistake have
forgotten to specify the fate samples so testing was limited to
the internal regression tests.
