Michael Niedermayer f8501d3399 avcodec/svq1dec: Check input space for minimum
We reject inputs that are significantly smaller than the smallest frame.
This check raises the minimum input needed before time consuming computations are performed
it thus improves the computation per input byte and reduces the potential DoS impact

Fixes: Timeout
