This speed 1 - uses variance threshold stolen from static-thresh
to determine split.  Any superblock with greater than the variance
set by static thresh * quantizer index squared is split. In addition
transform size is set to largest size less than or equal to partition
size, sub pixel filter is set to normal,  and only 12 modes are used
at all.

We leave it in rdopt.c as a local define for now - this can be removed
later. In all other places, we remove it, thereby slightly decreasing
the size of some arrays in the bitstream.

It remains as a local define in rdopt.c so we can distinguish between
split and non-split modes in the RD loop, but disappears outside that
scope in the codec.

The commit changed to use a new variant of Walsh-Hadamard Transform
by Tim Terriberry. This new variant has the best compression among a
number of variants that developed by Tim.

Fixes an issue with reducing branch cts in the encoder causing
a drop in performance. The bug was introduced in a previous
clean up patch.

Test: Went back to the offending patch, applied this same fix
to it, and checked that results are identical to the parent
of that patch.

Also merge all counters. This removes a few unused probability updates
from the bitstream.

This patch removes the implicit segmentation
experiment from the code base as the benefits
were still unproven as of the bitstream deadline.

size compound inter-inter prediction.

WIP: borg run testing

Change-Id: I2b318db4a03cdca5a8002b3fa6c0fa89b129288b

Added two flags to the frame header:

intra_only:
Signals that the frame is encoded using only INTRA
coding modes.

reset_frame_context:
Indicates that the coding context specified
in the frame header should be reset to default values before the
frame is encoded/decoded.

This patch changes the coefficient tree to move the EOB to below
the ZERO node in order to save number of bool decodes.

The advantages of moving EOB one step down as opposed to two steps down
in the other parallel patch are: 1. The coef modeling based on
the One-node becomes independent of the tree structure above it, and
2. Fewer conext/counter increases are needed.

The drawback is that the potential savings in bool decodes will be
less, but assuming that 0s are much more predominant than 1's the
potential savings is still likely to be substantial.

For 4x4 blocks valgrind points out the cache was uninitalized.
This resolves the issue by setting it.

This commit makes clean-ups in the rate-distortion loop for 4x4,
4x8, and 8x4 block sizes for the use of iterative motion search.

Removed unnecessary use of bmi in handle_inter_mode.

Deprecated loop over labels in the 4x4/4x8/8x4 block rd search.

Proposal for tuning the residual coding by changing how the context
from previous tokens is calculated. Storing the energy class of previous
tokens instead of the token itself eases the critical path of
HW implementations.

Adding API to read/write uncompressed frame header bits (it is not final
yet). Separate functions to read/write uncompressed header. Moving
clr_type, error_resilient_mode, refresh_frame_context,
frame_parallel_decoding_mode, frame_context_idx from compressed partition
to uncompressed frame header.

encoder. No change in bitstream.

This commit pulls the iterative motion search for compound inter-
inter out from handle_inter_mode_ as a separate function. Hence,
it is applicable to 4x4/4x8/8x4 level compound inter search to be
enabled later.

Also edit the rd loop for 4x4 inter block sizes for cosmetic
purpose.

Change-Id: Ibc71a11cbe5a26cd52faba01026cf8446cf4d2b4

Removed one 4x4 prediction step that was unnessary in the rd loop.
Removed a unused modecosts estimate from encoder side.

1. remove prediction mode conversion
2. unified bmode, same for key and non-key frame
3. set I4X4_PRED count for pdf to 0, as I4X4_PRED is no longer
coded ever. It is determined by ref_frame and block partition

This commit removes the use of bmi_ in the first-pass encoding by
forcing encode_intra4x4block_ to use DC_PRED, followed by DCT_DCT
only, as John suggested. This makes the need for bmi buffer only
up to 4 entries, instead of 16.

Hardware implementation needs to load coeff probs based on the
transform size. For selectable transform size, moving these bits
earlier in the bitstream adds some delay giving time to preload
the probs and speeds up the decoding process.
