    avcodec/h274 : add film grain synthesis routine

    This could arguably also be a vf, but I decided to put it here since
    
decoders are technically required to apply film grain during the output
    
step, and I would rather want to avoid requiring users insert the
    
correct film grain synthesis filter on their own.
    

    The code, while in C, is written in a way that unrolls/vectorizes fairly
    
well under -O3, and is reasonably cache friendly. On my CPU, a single
    
thread pushes about 400 FPS at 1080p.
    

    Apart from hand-written assembly, one possible avenue of improvement
    
would be to change the access order to compute the grain row-by-row
    
rather than in 8x8 blocks. This requires some redundant PRNG calls, but
    
would make the algorithm more cache-oblivious.
    

    The implementation has been written to the wording of SMPTE RDD 5-2006
    
as faithfully as I can manage. However, apart from passing a visual
    
inspection, no guarantee of correctness can be made due to the lack of
    
any publicly available reference implementation against which to
    
compare it.
