This patch adds a function to the key frame detection to test

This is intended to compliment the existing code and finds some
scene cuts that were previously being misssed.
Tested on two clips where the existing code was struggling to
identify the key frames this patch improved detection as follows.
Film clip 1: (detected / actual)
Old (2/5) New (5/5)
Film Clip 2
Old 4/11 and one false +, New 7/11 and 1 false +.
Short 4K Film Scene
Old 1/2 New 2/2
In testing so far I have not seen many extra false +'s though
it is likely that there will be some cases and this may need
further tweaking.
One one of our longer form film test reels ~20k frames)
the change picked up around 35 key frames that were
previously missed, mainly in darker scenes. There were a few
extra (or different) false positives cause by bright flashes or
explosions but these were cases where there was little
difference between inter and intra coding.

vp9-svc: Reorganize the simulcast mode
Set the lst/gld/alt_fb_idx and refresh flags for

This then avoids new code/function in update_references()

Safe guard zero median filter outcome case
In case median filter returns 0 value, bypass the Wiener filter
stage. This avoids potential divided by 0 case.
In the same place use a temp variable to take the Wiener filter
output instead of returning to the coeff array.

Set up Wiener variance for macroblocks in a frame
This commit introduces a Wiener variance term. For each block in
the source frame, we first estimate its film grain noise level
using median filter in the transform domain. Each transform
coefficient is then processed using Wiener filter to account for
the impact on the energy level due to film grain noise. The result
leads to a second moment of the denoised signal.
