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

This commit fixes a potential out-of-boundary memory access due to
the use of reuse_inter_pred_sby in the non-RD coding flow. It
resolves the corresponding asan error.

This commit fixes a mismatched use case of block size in non-RD
intra prediction check. The residual SSE and variance should be
calculated per transform block size, instead of operating block
size, which caused chrome valgrind warning on conditional jump
based on uninitialized value (webm issue 823). This commit
resolves this issue.

Refactoring to remove some duplication of probability
tables between tokenization and detokenization.

Use a weaker filter for second level arf frames.
Average gain across all sets and metrics ~0.3%
Remove code for arnr_type which is no longer
supported in VP9 which always uses a centered blur.
Re-factor and some cleanup.

Currently, vp9_diamond_search_sadx4() is only called when sse3 is
enabled, which is improper since sse2 optimization of sdx4df
functions are available. Changed to always use
vp9_diamond_search_sadx4().

There are sse2 optimization of sdx4df functions. Instead of calling
vp9_refining_search_sadx4 only when sse3 is enabled, call it always.

Use FAST_HEX in speed 5 and 6, which covers more points than
FAST_DIAMOND and improves motion search quality.
At speed 6, RTC set borg tests showed slight quality gain (psnr
gain: 0.143%, ssim gain: 0.226%). No noticeable encoding speed
change.

This commit combined the full pel and sub pel motion search into a
single function to avoid code duplication. The commit does not change
encoder outputs.

This commit enables a new quantization process for 32x32 2D-DCT
transform coefficient blocks. It improves the compression
performance of speed 5 by 1.4%. The overall compression gains of
speed 5 due to the new quantization scheme is 4.7%. It also includes
the SSSE3 implementation of the 32x32 quantization process.

In the previous version, only certain buffers in the macroblockd were saved and
the restored. In this version, all of the buffers are saved and restored. The
code was then rolled into a loop for readability.
Also contains a tiny fix for when the -DOUTPUT_YUV_DENOISED flag is used.

* Replace max_step_search_steps with constant MAX_MVSEARCH_STEPS
* Fold (reduce_first_step_size + speed > 5) into reduce_first_step_size
replacing uses of reduce_first_step_size that don't add the speed
check with zero.

vp9_rdopt is for making rd optimal mode decisions. vp9_rd is for all
other rd related routines. Anything used outside of making an rd optimal
decision belongs in rd.

Moved the threshold adjustment before reference flag checking,
which could set the threshold to INT_MAX for disabled reference
frame, and cause overflow if the adjustment is done after that.

Renamed updating_running_avg() to filter(). Extended function with the rest of
the filter procedure. Made all of the empirically-determined constants used in
VP8 into functions so they can be tweaked more easily.

As in VP8.
Currently, this parameter is set with the VP8E_SET_NOISE_SENSITIVITY flag.
The flag was not renamed so that we don't break the interface for webrtc. This
should probably be changed at some point in the future.
