The compiler was complaining about the 'bd' parameter being
unused in two functions.

Change _mm_srl_epi32 to _mm_sra_epi32. The difference is keeping
sign bits in shifting. Otherwise there are mismatchings between simd and c
functions, caught by unit tests.

The other change is fix a typo.

Allow the CDF update to operate in different modes, e.g. update vs no
update.

The update mode is transmitted in the uncompressed frame header of
every keyframe and intra-only frame.

This patch only adds bitstream signaling and API support. The
implementation of the update modes will be in later patches.

Tested in the low latency setting. Comparing the three options:

(1). Cut off temporal mv altogether.
(2). Use collocated mv referncing.
(3). Use mfmv referencing.

The current baseline is using (1).

The results are:
(2) improves the compression performance over (1) by -0.59% for
lowres and -0.65% for midres.

(3) improves over (1) by -1.05% for lowres and -1.43% for midres

it is necessary.

The CL makes the context design for single reference frame coding the
same as that for the compound reference frame coding. There are 3
contexts designed for each of the binary symbols for the single
reference frame scenario, and the designed contexts simply rely on the
counts of the references used in the neighboring two blocks.

Once this CL is merged, the coding of the reference frames, regardless
of single prediction or compound prediction, will all follow the same
context design pattern for all the binary symbols. The design logic is
much simpler and the lines of code for each binary symbol context
identification are reduced by 80%.

Further, this CL has obtained a small coding gain for 30 frames with
the default coding tools:

lowres: avg_psnr -0.015%; ovr_psnr -0.021%; ssim -0.002%
midres: avg_psnr -0.108%; ovr_psnr -0.139%; ssim -0.135%

When a coding block runs VERT_A partition, the coding order does
not follow raster order. This requires a special handle on the
bottom left square block to disable its reference towards the
top-right corner. Prior to this change the codebase would disable
the bottom-right square, as well as the right rectangular blocks,
from referencing the top-right mv. This commit fixes such check
condition to allow the right rectangular block to access the top
right mv.
