83f15a1228 avs: fix infinite loop on end-of-stream. 
The codec would keep returning the last decoded frame if the stream
contains B-frames, since it wouldn't clear that frame from the list of
frames to be returned to the user.

6eda85e15b sbrdsp.asm: convert all instructions to float/SSE ones. 
Since the values are floats, using the float operations
makes sense, improves performance on some CPUs and
makes the code SSE compatible instead of needing SSE2.

Based on suggestion by Jason.

7e1ce6a6ac dsputil: remove shift parameter from scalarproduct_int16 
There is only one caller, which does not need the shifting. Other use cases
are situations where different roundings would be needed.

The x86 and neon versions are modified accordingly.
