This patch made several changes.
1. Removed writing large_scale_tile bit to bitstream.
2. Created SET_TILE_MODE API in decoder to pass in tile coding mode
information.
3. Modified related unit tests.

BLOCK_SIZE enum.

The monochrome flags have been removed
from both the encoder and decoder, as this
is now an option in the colour space.

Modified the lightfield encoding example to accommodate HW implementation
requirements. Fixed the encoding scheme, generated a bitstream of a list
of references followed by the surrounding large scale tile coded frames.
All large scale tile coded frames use the same uncompressed frame header
and the same set of frame contexts. This example also wrote out the frame
header and frame contexts while encoding a large scale tile frame and
setting EXT_TILE_DEBUG to 1.

This is still a rather inefficient black+white encoder, since it carefully
computes some chroma data, but just doesn't write it. However, at least the
bitstream is now monochrome.

This experiment has been adopted, we can simplify the code
by dropping the associated preprocessor conditionals.

This experiment has been cleared by Tapas.

Also, fix a couple of hash signatures in the test while we are at it.

This reverts commit ab8bb8b8.

The reverted breaks many nightly run tests, reverting this temporarily
to allow nightly tests to detect other failures. Once the issues are
fixed, we can reenable the change in the reverted commit.

Updated the encoder flags for externally setting reference frames using
and updating to include latest changes in AV1.

1. For what reference frames to use, always initilize
cpi->ref_frame_flags with AOM_REFFRAME_ALL at the beginning of encoding
a frame. The internal ref_frame_flags starts from external flags. Added
AOM_EFLAG_NO_REF_LAST2 and AOM_EFLAG_NO_REF_LAST3 for LAST2 and LAST3.

2. For what reference frames to update, added ext_refresh_bwd_ref_frame
and ext_refresh_alt2_ref_frame for BWD and ALT2. Also, removed
AOM_EFLAG_FORCE_GF and AOM_EFLAG_FORCE_ARF since these are never
actually used. They can be added back if needed later.

max_tile was provisionally adopted at the working group meeting 2017-Oct-10

This patch also enables support for 64x64 and 128x128 superblock size for max tile
(rather than assuming 128). There is also one fix for max_tile in combination of
loop restoration where the width/height was in the wrong units for max-tile specific code.

1. Configure with --enable-experimental --enable-ext-tile and run "make"
to build.
2. Run "make test" to download lightfield test data: vase10x10.yuv.
3. Run lightfield encoder to encode whole lightfield:
  examples/lightfield_encoder 1024 1024 vase10x10.yuv vase10x10.webm 10 10 5
4. Run lightfield decoder to decode a single tile:
  examples/lightfield_decoder vase10x10.webm vase_tile.yuv 10 10 3 4 5 10 5

Note: Enabled use of AOME_USE_REFERENCE(previously deprecated) for this
example.

A separate prediction mode struct is added to allow
for uv-only modes (like CfL). Note: CfL will be
added as a separate mode in an upcoming commit.
