This commit extends the HBDMetricTests to handle testing for metric
computation where input source depth is different from working bit
depth.

Applied DST sse2 to 4x4 transform.

Fixed DST coefficient packing to satisfy 4x4 transpose requirement.

This fixes a bug in HBD sum of squared error computation introduced
in  #abd00505.

-Avoid unnecessary calculations
-Use SIMD when possible

Encoder is about 5% faster with the extra intra prediction angles
enabled.

Preliminary tests indicated that these changes make cost_coeffs
approximately 20% faster which is a 2% improvement overall

This makes all metric computation to locate at some place, also gets
rid of duplicate code between vp9 and vp10.

Adds new 32x32 masked 1-d transforms that combine 1-D length-16
DCT with length-16 identity transforms.

To be continued in subsequent patches.

This commit fixes an enc/dec mismatch in the dynamic motion vector
referencing experiment introduced in 837ef00.

This bug made the rd loop use one-side obmc (compound of the current
predictor and the predictors of the left mi's, while the above ones
are ignored by mistake) to determine whether to use obmc. This fix
improved the compression performance by ~0.6% on different test sets.

Add frame-level condition for reference masking: under external or
internal dynamic resize, allow for reference masking if none of
the references have been scaled.
Peviously, reference masking was turned off for the stream if dynamic
resize feature was enabled or an external resize event occurred.

reference_masking gives speed up with little/no loss in compression.
For speed 7 on rtc set: encoding time decreases by about 5-7%,
avgPSNR/SSIM goes down ~0.2%.

This commit fixes issue 1141. The issue was triggered in multi-tile
encoding. The change properly saves and restores the block context
information in the real-time mode selection process. It removes
several redundant memcpy operations in sub8x8 intra block mode search.

Change-Id: I35c9ad197f4bd500ec39b5fc833f052f19eee010

Removes the USE_DST2 flag that was on by default. DST2 performs
slightly better that DST1 and is faster to compute.

Using this we can eliminate large numbers of calls to predict intra,
and is also faster than most of the variance functions it replaces.
This is an equivalence transform so coding performance is unaffected.

Encoder speedup is approx 7% when var_tx, super_tx and ext_tx are all
enabled.

* changes:
  tests: quiet some unused parameter warnings
  vp9_error_block_test: prefer EXPECT over assert()
  vp9_encoder_parms_get_to_decoder: add missing initializers
  vpxenc: quiet unused param warning
  vpx_ve_predictor_4x4_c: quiet unused param warning

External dynamic resize with swapping width and height was
not handled properly.
Fix is to re-init loop-filter under certain condtions.

Modify unittest to test this case.
Without this change test will fail.

In this experiment, an obmc inter prediction mode is enabled for
>= 8X8 inter blocks. When the obmc flag is on, the regular block-
based motion compensation will be refined by using predictors of
the above and left blocks.
Fixed some compatibility issues with vp9_highbitdepth, supertx,
ref_mv, and ext_interp.

Adds a wiener filter based restoration scheme in loop which can
be optionally selected instead of the bilateral filter.

The LMMSE filter generated per frame is a separable symmetric 7
tap filter. Three parameters for each of horizontal and vertical
filters are transmitted in the bitstream. The fourth parameter
is obtained assuming the sum is normalized to 1.
Also integerizes the bilateral filters, along with other
refactoring necessary in order to support the new switchable
restoration type framework.

derflr: -0.75% BDRATE

[A lot of videos still prefer bilateral, however since many frames
now use the simpler separable filter, the decoding speed is
much better].

Further experiments to follow, related to replacing the bilateral.
