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.

rtcd: relocate 'extern "C" {' declaration
Place after pulling in forward declarations from the codec. This fixes
compilation of the tests under vs9.
Since 10783d4 Adds high bitdepth transform functions and tests
where vp9_idct.h was added to vp9_rtcd.h the tests are pulling in
vp9_systemdependent.h, which under visual studio include intrin.h. With
VS9 these include headers which define helper classes for intel
intrinsics. When including it in the tests (via vp9_rtcd.h) __cplusplus
is defined but vp9_rtcd.h would wrap declarations in 'extern "C" {'
causing a mismatch in linkage which resulted in compilation failure.
Add a conditional compilation macro to VP8 unit test.
In many tests in VP8, the denoiser is disabled. By adding this
conditional comilation macro, the unit test will not be included
when denoiser is not enabled.

Substantial reworking of code for arf and kf groups.
Substantial restructuring of the way we estimate
the rate of decay in prediction quality and determine
the arf interval and amount of boost used.
Also other changes to support moving to a lower first pass
Q which exposes some new features and allows us to better
distinguish genuinely static blocks from low motion or noisy
blocks.
Net gains now visible on all the test sets with std-hd PSNR up
1.87%. There are still some bad outlier cases but most of these
are low motion or slide show type content where the metrics
are already high at any given rate. The best + case is up by
more than 10%.

Set the skip flag to 1 for skippable blocks
If the partition block is skippable, which means no coefficients
for Y, U, and V planes, its skip flag is set to 1. No quality
change (verified by borg tests), and no noticeable speed change.

Remove memset of every external frame buffer.
Libvpx was memseting every external frame buffer before decode. This
was to work around a valgrind issue in our C loop filter. Most of
the time this was not needed and we have noticed some significant
performance loss on some platforms. Now we require the application to
zero out the buffers if it is using external frame buffers.

Remove redundant reference frame check in sub8x8 RD search
The valid reference frame check in sub8x8 rate-distortion
optimization search has been included in the ref_frame_skip_mask

that are not in effect.

Move call to vp9_rc_get_second_pass_params().
Call to vp9_rc_get_second_pass_params() moved from
Pass2Encode() to earlier in vp9_get_compressed_data(),
to ensure that two pass stats and parameters are
available before decisions such as frame scaling.
When a reference frame type is not in the frame buffer, the mode
search threshold will be set to INT_MAX, so as to effectively
turn off the mode entries in the rate-distortion optimization loop
that involves this reference frame type. This operation is now
integrated in the ref_frame_skip_mask scheme. This commit hence
removes the redundant mode search threshold setting.

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.
