CFL is disabled when skip_chroma_rd is enabled. This is done by reusing
the logic in CB4X4. To facilitate integration, the skip logic used in CfL is
moved inside the read/write functions.

Writes and reads alpha to and from the bitstream.

A special case is needed on the encoder side to handle prediction block
skips. Since whether or not a prediction block is skipped during CfL, a
rollback is required if the block was skipped and the alpha index was
not zero. The advantage of this is that no signaling is required when
the prediction block is skipped as it is assumed tha the alpha index is
zero.

A encode facade is added to the intra prediction facade as CfL requires
special encoder side operations.

The frame superresolution experiment currently makes no use of the
features of the loop restoration experiment. While this is planned for
the future, there is no reason to continue having frame superresolution
depend on loop restoration for now.

Frame superresolution was made dependent by having every preproccesor if
containing its config flag also depend on the loop restoration config
flag. Those if's are modified to only check the frame superresolution
flag by this patch.

Missing features:
* RDOPT (Forced on for certain blocks)
* Any form of border extension
* Non MI sized right and bottom edges
* MV prediction

Present features:
* Force intrabc for some blocks
* Carry intrabc in the bitstream
* Validate DV is causal
* Reconstruct intrabc block assuming border extension is unnecessary

This changes the behavior of the ext-inter compound modes
as follows:
* NEAREST_NEARESTMV, NEAR_NEARMV, NEW_NEWMV, ZERO_ZEROMV
  work the same as the corresponding compound modes without
  ext-inter
* NEAREST_NEWMV and NEW_NEARESTMV keep their current behavior,
  which is to use the first ref-mv candidate pair for their
  particular reference frames
* NEAR_NEWMV and NEW_NEARMV select between the second, third,
  and fourth candidate pairs.
* NEAREST_NEARMV and NEAR_NEARESTMV use the first candidate
  pair for the NEAREST component and the second, third, or
  fourth candidate pair for the NEAR component.

Also do some minor refactoring and fix compile errors
with --enable-ext-inter --disable-ref-mv

Transmit palette colors with delta encoding.
Coding gain on scrren_content testset:
overall 0.67%  keyframe 1.37%

Change-Id: I72ce9061dfddf933e9f7530f069955afcb07edf8

Added 2 tile encoding modes:
TILE_NORMAL mode supports the large-scale tile coding up to 1024 x 1024
tiles;
TILE_VR mode supports the large-scale tile coding and also the decoding
of a single tile.

TILE_NORMAL mode allows the non-vr content to be encoded in multiple tiles
without using the coding tool that are designed for vr applications.
