Check that the numerator is not zero. If it is, guess 30fps.

Fixes a clang IOC error in the quantize test. It's very unlikely for
this to occur in the wild because the setup in the quantize test is very
nonstandard.

The intrinsics version of the pair quant is slower than running it
individually.

-Use full bandwidth (when temporal layers is on) for checking switching.
-Normalize metric wrt num_blocks.
-Rounding fix to update of average noise level metric.
-Make default internal denoiser mode == kDenoiserOnYUV (in denoiser set_parameters()).
-Adjust some thresholds.

Avoid unneeded computation of mse in process_denoise.

Allow for option to apply spatial blur for temporal
denoising, under the aggressive denoising mode.

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).

Change-Id: I20330b2dcf3056287be37223302b2cab5fc103eb

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.

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.

Change-Id: I3c72e2260a616432eaf1f9545d4fb4d8e45cc7b0

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.

Change-Id: Ie0247f76b23219d95fe97dd70f23e097d742c249

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.

Added macro to conditionally compile some of the
post-processing functions only when CONFIG_POSTPROC
is defined.

This was causing the build for the generic-gnu target
to fail.

This patch did a cleanup following the commit "Save NEON registers
in VP8 NEON functions". The pushing/poping of callee-saved NEON
registers was moved into individual NEON functions. Therefore,
we don't need to save those registers at the beginning of codec.
The related code was removed.

Under a configuration change, where the bitrate suddenly decreases,
the buffer level may be larger than maximum allowed (for that first frame to be encoded after change_config).
This change keeps it clipped to its maximum level.

There were two problems with the format string in
the conditionally compiled print statement. It referred
to a variable that is no longer available and it used
incorrect format specifiers.

was merged into repository by mistake.

When a frame is dropped due to |buffer_level| < 0 for a given temporal layer,
the buffer level for the upper temporal layers was not updated (in calc_pframe_target_size()).
This change fixes that.

Also, use the layer per-frame-bandwidth for updating the buffer level
of the higher layers when a frame is dropped.

this was never fleshed out in the context of VP8, for which it was
added. for VP9 it has no meaning.
