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.

Place after pulling in forward declarations from the codec. This fixes
compilation of the tests under vs9.

Since
10783d4f 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.

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 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%.
