Delta quant doesn't make sense if the intent is to encode
the frame in lossless mode.

Enabling SEPARATE_GLOBAL_MOTION will remove the ability for
a block that uses zeromv with global motion to pick warped_causal
or obmc_causal as the motion mode. When this is enabled there is:

0.05% drop on lowres for global + warped enabled
0.15% drop on midres for global + warped enabled

0.12% drop on lowres with global + motion var enabled
0.07% drop on midres with global + motion var enabled
No performance change for global, warped, or motion var individually.

The initial CDF for each frame is stored in
the frame context. CDFs for actual coding are
stored in the tile structures, and these are
what get adapted. The initial CDF is replaced
by an average CDF derived from these tile CDFs.
This is carried forward to future frames when
backward adaptation is on.

CDFs are no longer set from the 8 bit probabilities
in backwards adaptation.

For now, 8 bit probabilities are maintained for
use in the encoder and for symbols which do not
have a CDF.

The variable "use_hbd" was defined but not used in four places in the
codebase. The warning that it wasn't used was missed by Jenkins
because it only tries one experimental flag at a time, but these
definitions were inside nested experimental flag conditions. Both
CONFIG_WARPED_MOTION and CONFIG_AOM_HIGHBITDEPTH had to be set for the
variables to be defined.

This patch deletes the unused definitions to remove the unused variable
warnings when the AV1 encoder and/or decoder are built with warped
motion and high bitdepth configured.

This change improves efficiency and means that tile groups
cause negligible loss (+0.03% BDR) in the current default
encoding configurations (1 tile group no matter how many tiles)
with frame-based wrapping.

In future, when wrapper formats support tile groups, lengths
can be omitted from the last tile in every tile group.

* code the palette color index using 45 wavefront
* interleave the coeff and palette color index in
  transform block level
* the above change does not change code efficiency

Details: 
The 45 wavefront scan allows to compute the ctx of
the diagonal samples' indices  at the same time. 
Interleaving palette indices and palette residual
on a transform block basis means that the entropy
 decoding and further processing of the palette 
residual is not delayed by the entropy decoding 
of all the color indices of the palette encoded 
block.
