The element of "idx" in the data structure of RefBuffer is a
connection between AV1_COMMON::RefBuffer and
AV1_COMMON::BufferPool::RefCntBuffer.

It is being used currently in many places in both the encoder and the
decoder. "idx" is not only used to track whether a reference buffer is
alive, but also serve as the connection to RefCntBuffer which contains
info that RefBuffer itself cannot access.

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.

This also avoids having 'bit_depth'/'bd' members whose presence
is decided by the preprocessor.

The goal is to simplify statements accessing the bitdepth value.
(instead of forcing them to also rely on the preprocessor to query
the member presence through #if CONFIG_HIGHBIDEPTH).

Stores the reconstructed luma pixels for each transform block inside a
prediction block. Rectangular transform blocks are supported.

As for RDO, after all the modes have been tested for luma, an extra
encoding is perform in order to store the reconstructed pixel values of
the best mode. These values are then used for RDO on the chromatic
planes.

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

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.

this change unifies the intra prediction angles so that 8x8 block has
the same number of angles and angle steps as 16x16 and 32x32 blocks.
the benefit is that HW implementation can have the same logic to
handle all block sizes. otherwise, prediction angles for 8x8 is
different from other block sizes, which requies special logic.
