Scale min_consec_zero_last wrt to #temporal layers,
and use full framerate as factor in noise metric.

On key frame, will always start with normal denoising mode,
but based on a computed noise metric (normalized mse on source diff)
may switch to aggressive mode (and back down again).

Modify zero_mv bias condition to include check that "closest" reference is last_frame.
This is needed for temporal layers, where the last_frame is not always the closest reference.
Also, constain zeromv_count to be for last_frame reference.

This is needed to update the width/height and stride parameters
for the reference buffers that the denoiser uses.

Since the UV decision to denoise is based on Y, we need to set
the default/initial denoiser decision_u/v to COPY_BLOCK,
to make sure if no uv_denoiser is applied we still update
(uv)running_avg with source.
Change-Id: I5af1c2afbd40c498cd3de208bea88c837099b24d
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.

For gcc, when libvpx config option debug is disabled, added the
flag -DNDEBUG to disable the assertions in libvpx for some speedup.

C version and sse2 version, and off by default.
For the test clip used, the sse2 performance improved by ~5.6%

Allow for an option to selectively apply the deblocking loop filter to the denoised
raw block, based on the denoised state (no-filter, filter with zero motion, or filter with non-zero motion)
of the current block and its upper and left denoised block.
This helps to reduce some blocking artifacts from the motion-compensated denoising.

When this compiler flag is enabled, the encoder will write a denoised,
uncompressed, version of the input to denoised.yuv.

By enabling the OUTPUT_YUV_SRC compiler flag, the encoder will write the raw
input to bd.yuv.
The functionality was mostly implemented, but in its previous state did not
compile.

In the current logic, if the sse for zero motion is smaller
than the sse for new_mv (i.e., best_sse), we may still end up
using the non-zero mv for denoising (if the magnitude of new_mv is above threshold).
This can happen for very noisy content, and can lead to artifacts.
This change ensures that we always use zero_mv (over new_mv) for
denoisng if sse_zero_mv <= best_sse.
