Improve key frame detection
Improve detection of key frames especially in low contrast
and low motion regions.
This patch adds a function to the key frame detection to test
for specific patterns in the intra signal in the first pass stats
that tend to be indicative of a key frame.
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.
Awaiting testing on standard sets.

Fix RD multiplier bug impacting AQ1.
Change to the default RD multiplier computation in set_segment_rdmult()
The default here is wrong as for modes like AQ 1 setting the rdmult based on the
segment ID for bsize will tend to result in the RD loop favoring partition sizes where
the resulting segment assignment has the lowest Q, as these partition sizes will be
then evaluated with a lower value of rdmult. For a valid rd comparison between
partition sizes within a single SB64 we need to use the same value of rdmult.
This change fixes an observed issue with AQ 1 where almost all the blocks were being
assigned to segment 0.

vp9-rtc: Change init level of denoiser & noise level
Change to init/reset level of the denoiser from
kDenLow to kDenMedium, and the init noise level to kLow.
This affects the denoiser level during the initialization
stage of the noise estimation.
Improves denoising for noisy content during init stage of
noise estimation, with little effect for low noise/clean content.

vp9-rtc: Add cyclic_refresh condition to segment reset
In non-rd pickmode for screen content:
this logic to reset segment should only be for cyclic_refresh
mode on, so add that condition explicitly.
There may be other uses of segments, like ROI, so we
should condition this reset logic on cyclic_refresh,
as it was intended for that mode only.

vp9-rtc: Modify skip golden mode check for 1 layer
For real-time CBR mode: golden reference mode testing is

This was done for svc mode. Here we add similar condition
for non-svc/1 layer encoding.
Reduces flashing block artifacts that can occur in background
