741b56fcee avcodec/svq1dec: Add assert to ensure "stages >= 0" 
This is currently always true, the assert protects against
future changes to the code breaking this assumtation

5a82ad644f svq1dec: Unbreak the scratch buffer allocation 
The input packets are always assumed to be padded and
the av_fast_ family of function takes a pointer to a pointer.

Thanks to Nicolas Dufresne <nicolas.dufresne@collabora.com> for
a similar patch.

Introduced in 7b588bb691.

7b588bb691 svq1: do not modify the input packet 
The input data must remain constant, make a copy instead. This is in
theory a performance hit, but since I failed to find any samples
using this feature, this should not matter in practice.

Also, check the size of the header, avoiding invalid reads on truncated
data.

0a373c31cb svq1dec: dont export the qscale table. 
SVQ1 has no qscales so the table is of no use, and it triggers a bug as
SVQ1 does not maintain the size of the table properly causing a crash.
