It does not help as an abstraction and adds dsputil dependencies.

This will allow for easier implementation of ARM-optimized functions in
libraries other than libavcodec.

Overall almost 4% faster, idct_add down from 350 to 85 cycles, idct_dc_add
down from 83 to 30 cycles.

30-50% faster than the C implementation, 0.5% overall speedup on
bourne.rmvb.

Perform dequantization while decoding coefficients instead of performing it
on the entire coefficients buffer.
Since quantized coefficients are very sparse, this usually causes a small
speedup. Speedup of around 1% on Panda board compared to the removed here
neon code. Global speedup is probably around 3%.
