Compares the sum of differences between the input block and the averaged
block. If they differ too much the block will not be filtered. Negligible
perfomance hit.

Add PRIVATE macro for adding private_extern directive for yasm
to hide global symbols. This is only enabled if -DCHROMIUM is used
with YASM.
Also fixed a small problem with rtcd_defs.sh to guard TEMPORAL_DENOISING.

This extends the denoiser to work for temporally scalable
coding.
I believe this also fixes a very rare but really bad bug in the original
implementation.

The change in assembly offset files to define values as const int broke
Windows build, because the variables are stored in .rdata section instead
of .data section.
This CL changes the integer peeking from .data to .rdata.

This fix addresses some problems with very complex clips like
handling of flashes on clips like crew (which was made worse
by an earlier patch (derf and std-hd)).
Most clips a small effect but some between 1 & 2%
Derf +0.039, +0.211%
YT +0.042, +0.083%

Removed the local scaling factor est_max_qcorrection_factor

anyway)
Cap range of total correction factor.
Slight change to break out case to turn off arf.

This change is to allow obj_int_extract to extract all integers
in the data segment. With the const keyword these variables are
forced into the .rodata segment even for zero variable value.
We had a problem before that zero valueed variables would get
assigned to BSS segment that fooled obj_int_extract to give
incorrect values.

After a key frame encoding, the frame type could change while
filtering is still going on. Pass the frame type as parameter to the
loopfilter function and don't read it from common storage.
vp8cx_set_alt_lf_level has to be done before packing the stream.
Currently alt_lf_level is not used so there hasn't been any visible
problem here.

The two-pass code does not support the case where the application
changes the frame size dynamically. Add this case to the validation
checks in the vpx_codec_enc_config_set() path.

* changes:
Add initial keyframe tests
Move all tests to test/ directory
Enable unit tests by default
Build unit tests monolithically
configure: initial support for CXX, CXXFLAGS variables
Resolution changes in calls to vpx_codec_enc_config_set() would cause
a memory leak due to failing to release the lookahead and alt ref
buffers.

Reverted part of change in memory alllocation code, which ensures
that the function returns 0 and encoder works correctly when
CONFIG_MULTI_RES_ENCODING isn't turned on.

The commit changed how baseline 8x8 coefficient probabilities are
initialized, to be consistent with the initialization of baseline
4x4 coefficient probabilities.
The commit does not have any effect on compression.

TestDisableKeyframes
TestForceKeyframe
TestKeyframeMaxDistance

Rework unit tests to have a single executable rather than many, which
should avoid pollution of the visual studio project namespace, improve
build times, and make it easier to use the gtest test sharding system
when we get these going on the continuous build cluster.
Change-Id: If4c3e5d4b3515522869de6c89455c2a64697cca6
Use CXX rather than assuming g++ to invoke the compiler. Also introduce
separate CXXFLAGS, as certain CFLAGS we enable by default cause warnings
with g++.

aligned buffers improve performace. this change brings vpxenc &

Remove dependency on amount and speed of motion as this
may not behave well across different image sizes.
Tweak impact of % inter.
Add in experimental adjustment based on relative quality of an
older second reference frame.
Cap range of decay values allowed.
Some small + effect on derf but -ve on yt & hd at this stage.

In multi-resolution encoding, frame_type decision for each frame
is made by the lowest-resolution encoder. For all other higher-
resolution encoders, kf_mode is always set to VPX_KF_DISABLED,
and they are forced to use the same frame_type picked by the
lowest-resolution encoder.

I now see I didn't write a very long description, so let's do it
here then. We took a pretty big quality hit (0.1-0.2%) from my
recent fix of the inversion of arguments to vp8_cost_bit() in the
RD reference frame costing. I looked into it and basically the
costing prevented us from switching reference frames. This is of
course silly, since each frame codes its own prob_intra_coded, so
using last frame cost indications as a limiting factor can never
be right.
Here, I've rewritten that code to estimate costings based partially
on statistics from progress on current frame encoding. Overall,
this gives us a ~0.2%-0.3% improvement over what we had previously
before my argument-inversion-fix, and thus about ~0.4% over current
git (on derf-set), and a little more (0.5-1.0%) on HD/STD-HD/YT.

base the static image test off a measure of 0,0 motion
instead of the decay accumulator value.
Change "transition to still detection" to compare the
decay rate from successive frames.
Minor tweak to the arf extra boost given based on the
number of frames affected.
Removed unused variable mod_err_per_mb_accumulator.
