vp8 denoiser fix: Update denoised altref on key frame.
On a key frame, the denoised-running_avg for all references
frames should be updated with the source.
The altref denoised-running_avg was not being updated on key frame,
this fixes that.

Turn on adaptive pred filter scheme for sub8x8 below 720p
For sequences of resolution below 720p, the encoder will check
intra prediction modes and inter prediction modes from LAST_FRAME.
This commit turns on adaptive prediction filter scheme for sub8x8
blocks, where inter prediction modes are enabled. For the test
sequence bus at CIF, the speed 2 runtime goes down from 17879 ms
to 16783 ms, i.e., 6% speed up. The compression performance of
derf set is down by -0.128%.
This patch adds back in code that checks that the frame
size lies within defined bounds was inadvertantly removed

the existing ability to use externally allocated memory.

Adds support for raw yuv files for 422/444
Adds support for raw yuv inputs in 422/444 sampling for use
in profiles 1 and 3.
New options added to vpxenc are:
--i422 and --i444, which are to be used in conjunction with
--width, --height, and --fps for proper raw yuv handling.
A new option is added to vpxdec:
--rawvideo, which enforces raw yuv video output for the
bit-stream decoded irrespective of 420, 422 or 444 sampling.
The existing options --i420 and --yv12
are specialized for use only for 420 content.

Changes to rd balance and multi-arf bug fix.
2 pass only change to calculation of rd mult based on Q.
Make a small adjustment based on frame type and also
replace adjustment based on iifactor with an one based
on the ambient GF/ARF boost level.
Also fix multi arf bug / issue.
Overall these change give an slight improvement in ssim
but hurt psnr a little.
Fix show_existing_frame not decreasing frame buffer ref counter.
The issue was introduced by commit g7c43fb6. If current frame
is repeated from existing-ref pool, frame buffer ref counter
is not decreased, so buffer isn't released. Decoder fails being
unable to allocate new frame buffer at some point.
Added a test vector to verify that the condition will not
recur later. Test vector was generated by the code in this patch:

VP9 Denoiser denoises after mode/bsize search
In vp8, statistics are collected about the different modes as they are searched.
This process is more complicated due to the variable block size. Fields were
added to the PICM_MODE_CONTEXT struct to hold this information for each point in
the search. The information is then taken from the appropriate part of the tree
during denoising.

Generalizes yuv read in preparation for support for reading 422/444

All changes are for spatial svc only.
1. Enable encoding hidden frames in each layer and use alt reference idex to reference the hidden frame in each layer
2. Use golden reference idx for spatial reference
3. For those layers that don't have hidden frames (caused by lack of frame buffers), reference a hidden frame in lower layers
4. Add "auto-alt-refs" in svc options
