In the beginning of encoding and bitstream packing,
the frame context in common of codec is copied to the frame context
in each tile.
Initial prob and context is based on flat probability and
does not come from table at the moment.

The bd-rate change for the test set objective-1-fast
on awcy with high delay mode is:

PSNR   PSNR  HVS  SSIM  CIEDE 2000  PSNR Cb PSNR Cr MS SSIM
-0.77  -1.05      -0.74 -0.67       -0.67   -0.77   -0.88

In preparation for enabling backward updates of contexts for PVQ.
1. Default prob setting for PVQ,
which is based on flat probabilities at the moment.
2. At the end of encoding a frame, average probablities and expected values
of PVQ are copied to the frame context.

When a global translation model is found, the only 3 bits
of precision are used for the motion parameters. This case
uses a smaller precision than the translation parameters
in a global model that is rotzoom or greater.

This fixes errors with EC_ADAPT where the CDF tables
are not built from 8-bit probabilities.

Running this test in Jenkins causes all but trivial changesets to
fail unless the hash is changed. Other changes in master
can meanwhile cause the hash to be out of date by the time
of merge even if it is changed, so rebases of previously
passing changesets will then fail again.

Move most of the code of inverse_transform_block to
av1_inverse_transform_block such that encoder can use the
function as well.

Use av1_inverse_transform_block in av1_encoder_block_intra.
This will make the code cleaner.
