fd8b90f5f6 vp9: fix overflow in 8x8 topleft 32x32 idct ssse3 version. 
Also disable the mmx/iwht optimization when the bitexact flag is set.
With synthetically coded coefficients (i.e. these that lead to a
residual well outside the [-255,255] range), our optimizations will
overflow. It doesn't make sense to fix the overflows, since they can
only occur on synthetic input, not on real fwht-generated input. Thus,
add a bitexact flag that disables this optimization.

e8c45b96f4 avcodec/libopenh264enc: Use av_log() to log messages 
File libopenh264enc.c has been modified so that the encoder uses av_log()
to log messages (error, warning, info, etc.) instead of logging them
directly to stderr.  At the time the encoder is created, the current
ffmpeg log level is mapped to an equivalent libopenh264 log level.  This
log level, and a message logging function that invokes av_log() to
actually log messages, are then set on the encoder.

da64bd6a99 aaccoder: tweak PNS implementation further 
This commit changes a few things about the noise substitution
logic:
 - Brings back the quantization factor (reduced to 3) during
   scalefactor index calculations.
 - Rejects any zeroed bands. They should be inaudiable and it's
   a waste transmitting the scalefactor indices for these.
 - Uses swb_offsets instead of incrementing a 'start' with every
   window group size.
 - Rejects all PNS during short windows.
Overall improves quality. There was a plan to use the lfg system
to create the random numbers instead of using whatever the decoder
uses but for now this works fine. Entropy is far from important here.

b6cc8ec7ec aaccoder: add frequency scaling and quantization correction for PNS 
This commit once again improves the PNS implementation by scaling the
thresholds with frequency. The thresholds get looser as the frequency
increases since higher frequencies are basically noise to human ears.

Also, this introduces quantization error correction for PNS. Should
the error be too much, no PNS will be used. The energy_ratio is used
to regulate the actual encoded PNS energy: if the generated PNS
energy is higher than the energy from the psy system, energy_ratio
is used to correct it so that hopefully once requantized and
transmitted the value in the decoder will be closer to what the
encoder has.
