decoder: Ignore RASL NALs after flush
...
After flush, if the first slice NAL sent to decoder is a CRA
picture, then it may have associated RASL NALs that need to
be skipped as they may contain references to pictures that
are not present in the bitstream that is fed to the decoder.
Currently decoder was handling this case only at the start
of decode and after receiving an EOS NAL. Now it is updated
to ignore such RASL NALs associated with CRA after flush as
well.
This is needed to handle seek in clips, where CRA NALS are
marked as sync points.

Misplaced local array on stack is resulting in color artifacts in
decoded yuv. It worked so far, because the array luma_nbr_flags_4x4[]
was always allocated on the same address and thus preserved values from
previous iteration.
