340c7a48e6 Change to segment ref frame feature.
Simplify feature to only support a single reference frame
instead of a mask.

2584a5e5e5 Add cheap show-buffer operation
Adds the ability to have the decoder show one of the existing reference
frames directly, without having to code it indirectly as a series of
skip blocks.

6ef805eb9d Change ref frame coding.
Code intra/inter, then comp/single, then the ref frame selection.
Use contextualization for all steps. Don't code two past frames
in comp pred mode.

ad34368786 New intra mode and partitioning probabilities.
Split partition probabilities between keyframes and non-keyframes,
since they are fairly different. Also have per-blocksize interframe
y intramode probabilities, since these vary heavily between different
blocksizes.

Lastly, replace default probabilities for partitioning and intra modes
with new ones generated from current codec. Replace counts with actual
probabilities also.

e6485581fe Remove splitmv.
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.

84c5ed0e98 Bugfix in forward update with modeling on.
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.

9e5bb9598c Add intra_only and reset_frame_context flags
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.

b8b3f1a46d Balancing coef-tree to reduce bool decodes
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.

Results on derf300: -0.237%

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

80812829c2 Moving txfm_size bits before prediction mode bits.
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.
