s->ref_pics[i] is later used as ref argument of interpolate_refplane,
where it is dereferenced.
If it is NULL, it causes a segmentation fault.

If bytes is large enough, bytes*8 can overflow and become negative.
In that case 'bufsize -= bytes*8' causes bufsize to increase instead of
decrease.
This leads to a segmentation fault.

alsdec: only adapt order for positive max_order
See: 58d605ee9b

buf_idx + data_unit_size can overflow, causing the '> buf_size' check to
wrongly fail.
This causes a segmentation fault.

For max_order = 0 the clipping range is invalid. (amin = 2, amax = 1)

The minimum of the ath(x, ATH_ADD) function depends on ATH_ADD.
This patch uses the first order approximation to determine it.
For ATH_ADD = 4 this results in the value at 3407.06812 (-5.24241638)
not the one at 3410 (-5.24237967).

If max in clean_index is set to a negative ast->sample_size, the
following loop never ends:
while (max < 1024)
max += max;
Thus set ast->sample_size to 0 if it would otherwise be negative.

If bit_rate is negative, it can trigger an av_assert2 in av_rescale_rnd.
Since av_rescale returns int64_t, but st->codec_bit_rate is int, it can
also overflow into a negative value.
