This was still being used for CDFs whose size might not match the
declared array size. We replace it with an intialization macro
intended explicitly for this purpose.

This should be the same number of operations as the non-ec_smallmul
version (though ideally we'd use the real 15-bit probability
natively).

Encoder output should not change, and all streams should remain
decodable without decoder changes.

This only changes the internal coding engine. We convert CDFs into
iCDFs at the "bool" reader <-> daala_ec boundary.

Decoder output should not change.

This removes one subtraction from the CDF search loop (reducing the
dependency chain for reading from the CDF) at the cost of one
increment and decrement during renormalization (easily absorbed by
the reorder buffer).

There should be no change in decoded output.

this change adds the following filter tap options:
1. add options to replace 15 tap filter with 9 or 11 tap filter
2. force chroma plane to only use maximum 7 tap filter

above options are disabled by default

This CL is targeted to improve the objective/subjective quality of the
"ext-refs" coding tool.

Tuned the frame rate factors as follows:

(1) BRF_UPDATE:
    Decreased from INTER_HIGH (1.5) to GF_ARF_LOW (1.25);
(2) Both LAST_BIPRED_UPDATE and BIPRED_UPDATE:
    Increased from INTER_LOW (0.80) to INTER_NORMAL (1.00)
, which is to reduce the bits allocated to the BWEDREF frame whereas
to increase the bits allocated to the bi-directionally predicted
frames.

Obtained a coding gain in overall PSNR as follows, compared against
the original ext-refs:

lowres: BDRate -0.181%
midres: BDRate -0.090%
hdres:  BDRate -0.701%

This creates a central function which defines when a
block should be warped. It also refactors the
WARPED_MOTION code so that all calls to av1_warp_plane
happen in the same location.

No change in performance.

The greedy search method improves the BD-rate over the baseline by
more than 0.2% for lowres test set. Larger gain 0.55% is observed for hdres test set.

[2017.04.06] Cleanup to remove redundant computation. On a local linux
machine, the greedy method is now faster than the trellis method in
encoding the first 100 frames of foreman_cif. However, the BD-rate seems
to become smaller due to the recent changes to the codebase.
[2017.04.06-2] Style changes to meet the requirements.
remove "greedy-optimize-b" in configure
[2017.04.10] Move the changes under the macro USE_GREEDY_OPTIMIZE_B
[2017.04.11] Adjust rdmult to accommodate CpuSpeedTest
[2017.04.12] Set USE_GREEDY_OPTIMIZE_B to 0 at the request of debargha@.
[2017.04.13] Move greedy implementation of optimize_b into a separate
function with the same name (selected by USE_GREEDY_OPTIMIZE_B, default
is 0)

$ cmake path/to/aom -DCMAKE_TOOLCHAIN_FILE=path/to/aom/build/cmake/toolchains/mips64-linux-gcc.cmake

MSA is supported via addition of -DENABLE_MSA=1. Support for i6400
and p6600 targets can be enabled by passing -DMIPS_CPU=i6400 and
-DMIPS_CPU=p6600 respectively.

The while loop may become infinite loop due to bitstream error.
Therefore, we add a breaking rule to avoid that.

This fix the invalid tx_type error happened when mb_to_right_edge
is negative

The invalid tx_type error will cause bitstream error and then
let the decoder hang in the while loop of read_golomb()

HW does not support < 4x4 prediction. To limit the bandwidth
requirement, for small blocks, only blend with neighbors from one
side. If block-size of current plane is 4x4 or 8x4, the above
neighbor will be skipped. If it is 4x8, the left neighbor (dir = 1)
will be skipped.
This change will keep the bandwidth requirement of OBMC not more
than what is required by normal compound inter modes.

Adds filters for 1/32 subpel precision for warping.
To use 1/32 subpel precision make WARPEDPIXEL_PREC_BITS 5.
By default, WARPEDPIXEL_PREC_BITS is set as 6 in common/mv.h,
which uses 1/64 subpel precision.

If 1/32 precision is used, BDRATE drops:
on lowres:
-1.101 (vs. -1.186% with 1/64) w/warped-motion
-1.587 (vs. -1.650% with 1/64) w/global-motion

on cam_lowres:
-2.638 (vs. -2.707% with 1/64) w/warped-motion
-3.396 (vs. -3.453% with 1/64) w/global-motion

Optionaly filter 8x8 skip blocks, but still leave superblocks that are
completely skipped unchanged.  Use one bit in the dering level to
signal replacing the signal for dering damping.

This works better with cb4x4 that now is enabled by default.
