Ronald S. Bultje 93b53ffb1a dca: don't use av_clip_uintp2(). 
The argument is not a literal, thus causing the ARM v6 or later
builds to break.

Christophe GISQUET 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.

Christophe GISQUET dabf8dd34a SBR DSP: unroll sum_square 
The length is even, so some unrolling can be performed. Timings are for x86:
- 32bits: 102c -> 82c
- 64bits:  82c -> 69c

Also, do not give AVCodecContext.frame_size priority for muxing.

Updated 2 FATE references:
dxa-feeble - adds 1 audio frame that is still within 2 seconds as specified
             by -t 2 in the FATE test
wmv8-drm-nodec - durations are not needed. previously they were estimated
                 using the packet size and average bit rate.

Justin Ruggles 8d1a20aa7c aiffdec: do not set AVCodecContext.frame_size 
It is unnecessary. Also, for some codecs we're reading more than 1 frame per
packet. Instead we use a private context variable to calculate the bit rate,
stream duration, and packet durations.

Updated FATE seek test, which has slightly different timestamps due to a
more accurate bit rate calculation.
