intra-interp experiment allows intra prediction to use different
interpolation filters. It was part of the ext-intra in the nextgenv2
branch.

Use the proper scaling factor to map transform block offset to the
pixel offset in the reconstruction process.

1) Not every transform's internal signal is designed to fit in 16 bits.
2) If overflow happens in this function, it indicates that we need to
adjust the txfm's scaling. We shouldn't mute the overflow signal.
3) Saturation might be handy when all of our transform design are stable,
but I don't think we are at the stable point yet.
4) This will fix C/Trans16x16DCT.AccuracyCheck/1 failure in highbd mode.

The previous refactoring CLs resolve all the potential issue
related to these two conditions. It is safe to remove them now
from the cb4x4 mode.

Change-Id: Ieeb1ca2804318c1f46b60c041538f8ca5f6ba0e7

Change the table content to support 4x4 mode_info unit. Refactor
partition_plane_context() to reflect the fact that the minimum
partition block size is 8x8.

Change-Id: Id26fcfba8d74efdb9ae316c9d066cd65358dd7e6

Replace the 4x4 block counting with minimum transform block size
counting. This retains identical coding statistics.

With this patch affine or homography models can be enabled
by simply changing the value of the GLOBAL_TRANS_TYPES
macro in common/mv.h to 4 and 5 respectively. Currently
it is left at supporting only rotzoom. There is a small
gain with enabling affine.

Also refactors costing to change based on the model type.

- For resolution > 1080p, this CL also disables upsampled
  references for best and realtime quality deadline besides
  good quality deadline.
  The following CL only disabled the good quality deadline:
  https://chromium-review.googlesource.com/#/c/405761/

- The issue was found by a segmentation fault happened in 4K
  --best mode encoding test. Current CL fixes the encoder
  segmentation fault temporarily.

- Another bug is filed:
  https://bugs.chromium.org/p/aomedia/issues/detail?id=108
  to track down the segmentation fault.

Relative to previous ext-inter:
lowres: -0.177%
     or -0.029% (with USE_RECT_INTERINTRA = 0)

* When predicting interintra modes, the previous code did not provide
  the intra predictor with the correct context during rdopt. Add an
  explicit 'ctx' parameter to the relevant functions, to provide this
  context.
  This fixes a nondeterminism bug, which was causing test failures in
  *EncoderThreadTest*

* For rectangular blocks, build_intra_predictors_for_interintra needs
  to overwrite part of the context buffer in order to set up the
  correct context for intra prediction. We now restore the original
  contents afterwards.

* Add a flag to enable/disable rectangular interintra prediction;
  disabling improves encoding speed but reduces BDRATE improvement.

Change-Id: I7458c036c7f94df9ab1ba0c7efa79aeaa7e17118

Map the block offset to pixel positions in the unit of minimum
