b962646fc5 Re-worked header files
Various header/test files had to be re-worked in order to
build "Remove cm parameter from vp9_decode_block_tokens()".

This patch reverts the "Remove cm" part and only contains
the re-worked header files.

1d7ccd5325 Relocate memory operations for common code
With the sad functions, and hopefully the variance functions soon,
moving to the vpx_dsp location, place the defines used in the
reference C code in a common location.

(see I3a05cf1610679fed26e0b2eadd315a9ae91afdd6)

For the test clip used, the decoder performance improved by ~2%.
This is also an intermediate step towards adding back the
mode_info streams.

6910e92d04 dc quantizer fix for 32x32 transforms
The rounding factor needs to be scaled down by a factor of 2.
Also, the quantized and dequantized coefficients are memset to 0
when dc quantizer is used.

a306bd8274 Use the RTC optimizations when in high bitdepth mode.
Change 72193 made the encoder behave differently
when configured with and without high bitdepth.
This change means the same algorithm is used for both.

7428cebe4f Rework forward txfm/quantization skip system in RTC coding mode
This commit allows more aggressive decision to skip forward
transform and quantization for luma component in RTC coding mode.
The chroma components remains going through the normal coding
routine, since they are not included in the non-RD mode search
process.

It reduces the runtime cost by 2% - 10%. In speed -6,

c6908fd5f7 Combine fdct8x8 and quantization process
This commit reworks the forward transform and quantization process
for 8x8 block coding. It combines the two operations in a single
function to save a store/load stage of the original transform
coefficients. Overall the speed -6 is slightly faster (around 1%
range). The compression performance of speed -6 is improved by
3.4%.

c70cea97ac Remove mi_grid_* structures.
mi_grid_* are arrays of pointer to pointer. They save the pointers that point
to the MIs in cm->mi. But they are unnecessary and complicated. The original
goal was to remove MODE_INFO_t copy. But with an extra MODE_INFO_t pointer
inside MODE_INFO_t, same goal could be achieved.

This commit totally removes the mi_grid_* structures. But there are still
many dummy MODE_INFO_t inside cm->mi which are a waste of memory. Next commit
will do on-demand MODE_INFO_t allocation in order to save these memories.

10783d4f3a Adds high bitdepth transform functions and tests
Adds various high bitdepth transform functions and tests.
Much of the changes are related to using typedefs tran_low_t
and tran_high_t for the final transform cofficients and intermediate
stages of the transform computation respectively rather than fixed
types int16_t/int. When vp9_highbitdepth configure flag is off,
these map tp int16_t/int32_t, but when the flag is on, they map
to int32_t/int64_t to make space for needed extra precision.

This commit enables a new quantization process for 32x32 2D-DCT
transform coefficient blocks. It improves the compression

speed 5 due to the new quantization scheme is 4.7%. It also includes

7557a65d16 BITSTREAM: Handle transform size and motion vectors more logically for non-420.
This breaks the profile 1 bitstream.

Don't force non420 uv transform size to 1/4 y size. In the 4:2:0 case the
chroma corresponding to a luma block is 1/4 its size. In the 4:4:4 case
chroma and luma planes are the same size. Disallowing larger transforms
can result in a loss of compression efficiency and is inconsistent.

For sub-8x8 blocks only average corresponding motion vectors.

4:2:0 and profile 0 behavior remains unchanged.

ccba289f8d Fast computation path for forward transform and quantization
This commit enables a fast path computational flow for forward
transformation. It checks the sse and variance of prediction
residuals and decides if the quantized coefficients are all
zero, dc only, or more. It then selects the corresponding coding
path in the forward transformation and quantization stage.

It is currently enabled in rtc coding mode. Will do it for rd
coding mode next.

In speed -6, the runtime for pedestrian_area 1080p at 1000 kbps
goes down from 14234 ms to 13704 ms, i.e., about 4% speed-up.
Overall coding performance for rtc set is changed by -0.18%.
