The monochrome bit has been removed from the end
of the sequence header.
Monochrome is now coded as a type of colorspace.

Encode in monochrome by using
  aomenc --color-space=monochrome ...

Adds spatial prediction to standard segmentation instead of a separate
segmentation feature.
When using temporal prediction skipped blocks are flagged as mispredicted.

Rather than having a set of parameters for each of the 6
COEF_BANDS, we have 1 for DC and 1 for AC coefficients.
No change in performance since all of the bands had the
same parameters.

max-tile remains off by default until more testing is performed but I would
like to check in the fixes that are known so far to prevent this patch getting too big

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

This patch fixes the following issues:
- max_tile is fixed to suport superblock size 64x64 as well as 128x128 (ext_partition support)
- max_tile is fixed in combination with loop_restoration
- max_tile is fixed in combination with ext_tile (Bug: 1013)
- max_tile is fixed in combination with lv_map and 64x64 subperblock (lv_map memory allocation
  fixed for 64x64 superblock)
- max_tile reports the size of the first tile for inspection.c used by the analyzer

Previously CDEF was implicitly disabled for a filter block if all its
sub-blocks were skip, and no bits for that block was signalled.  That
required the CDEF signal to be transmitted at the end of the block,
and it was not possible to begin the filtering of the block before
that.

This patch moves the signalling to just after the first zero skip bit
within a 64x64, 128x64, 64x128 or 128x128 block.  If sub-blocks are
skip, then no CDEF bits will be signalled, as before.  Also, the skip
condition flag has been removed so it's always known at the skip flag
whether a coding block is to be filtered or not.

The CfL context is now stored inside MACROBLOCKD instead of
MACROBLOCKD only storing a pointer to the CfL context.
The intent is to avoid race conditions as MACROBLOCKD is stored
inside ThreadData. This change also simplifies CfL Initialization.

Change-Id: If26e36c49e62f2bd2626e81073a3d52d7e78a719

The change can be temporarily reverted by setting ALLOW_128X32_BLOCKS
to 1 (for easy "is this better?" testing: we'll get rid of the option
once it's clear what we're doing).

Since this means we have to modify the "num_partition_types"
calculation in functions like read_partition, we move it into a helper
function called partition_cdf_length(). Doing this makes the bodies of
read_partition and write_partition somewhat simpler than they were.

temporal segment map prediction from LAST frame instead of previous

A new block mode, referred to as skip_mode is added. If a block is
coded as skip_mode, it will be inter-coded, with its references and
motion vectors derived from its neighboring blocks with zero-residue.
Otherwise, the block can be coded in the current intra or inter mode.

The computational load on skip_mode evaluation at the encoder should
be kept minimum. No transform size / type evaluations are needed.

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 bit appears in the sequence header. At the moment, it does
nothing, but it will mean that we don't encode (or read) chroma
planes.

This patch adds the flag to the sequence header, and also adds an
encoder option (--monochrome) which enables it. At the moment, this
doesn't do anything except cause the bit to be set correctly in the
header.

The control of using reference frame motion vector is a separate
factor from the existence of previous frame motion vectors. This
commit decouples these two, such that the encoder can control the
use of reference motion vector. When it is used, one can further
identify if the previous frame exists or not, then to decide if
need to force use_prev_frame_mvs to be zero.

This solves the issue where the previous frame mvs is set to be
0 and it accidentally shuts off the access to all other existing
referece frames mvs in the mfmv system. It brings back the coding
performance gains to normal.
