In the longer term the encoder should allow compound as long
as one of the buffers has opposite sign bias and as per the decoder
this buffer is then set as the fixed reference. However at the moment
the encoder and RD loop only supports the case where the ALTREF_FRAME
buffer (or third of the 3 allowed in any given frame) is the odd one out.
This patch fixes a bug that would allow compound inter and set
fixed ref to ALTREF_FRAME when it is not the odd one out.

Split partition probabilities between keyframes and non-keyframes,

Added structures to support independent rd thresholds
for different block sizes (and set experimental block
size correction factors).
Added structure to to allow dynamic adaptation of thresholds
per mode and per block size basis depending on how often
the mode/block size combination is seen (currently fixed factor).
Removed some unused variables.
TODO
- Adaptation of thresholds based on how often each mode chosen.
- The baseline mode values could also be adjusted based on
the block size (e.g. for a particular intra mode use a low threshold
for 4x4 prediction blocks but a relatively high value for 64x64.

This commit makes operations of the superblock intra coding rate
distortion optimization consistent with those used in the encoding
process. Given the test prediction mode and transform size, the rd
optimizer encodes and reconstructs each transformed block of the
superblock consecutively, then computes the total rate-distortion
costs accosicated with the current superblock to select the coding
decisions.
It achieves coding performance gains:

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.

forwards update of a structure this size is problematic. I

In current code, motion vectors got from single prediction mode are used
in compound prediction mode directly. These motion vectors may not give
accurate prediction since they are searched independently. In this patch,

Overall PSNR: 0.570%(derf), 0.918%(stdhd);

This allows removing a large number of transform size specific functions,
as well as supporting 444/alpha by routing all code through the
subsampling-aware path.

The number of reference buffers is extended to 8 and
a reference sign-bias added for the LAST_FRAME.
Whilst the number of reference buffers used by an
individual frame remains unchanged at 3, these may
now be selected from 8 possible buffers.

With this, encoder/decoder appear to match with sb8x8 experiment.
Needs some larger-scale testing.
Change-Id: I44d3cac37b3c98264985ed0a0fc763c30089aa64
Creates a common encode (subtract, transform, quantize, optimize,
inverse transform, reconstruct) function for all sb sizes, including
the old 16x16 path.

Don't allow i4x4 except for sb8x8 recursion step. Read only 4 (not 16)
i4x4 submodes if we are i4x4.

This doesn't affect the output, because in previous cases where the
values were uninitialized, this was because the mb_row/col is outside
the codable area, and thus encode_sb will test them for the next
decomposition-level, but return right after that on size-check. All
this does is prevent a warning in valgrind.

Work-in-progress, not yet ready for review. TODO items:
- bitstream writing (encoder) and reading (decoder)
- decoder reconstruction
Change-Id: I5afb7284e7e0480847b47cd0097cb469433c9081
Changing the order of probabilities inside mb_segment_tree_probs in order
to use treed_read/treed_write function instead of custom code.
Change-Id: I843487d5057913b9358db73da270893eefecc6c8
Moving common code from encoder and decoder to vp9_get_qindex function.
Also moving quant-related constants from vp9_onyxc_int.h to
vp9_quant_common.h.

Separate the decoding process of 4x4 block based coding (both intra
and inter) from decode_mb and move it into decode_atom_. This allows
to further move the rest per 16x16 block decoding of decode_mb into
decode_sb, and hence eventually deprecating decode_mb when SB8X8 is
enabled.
Change-Id: I678cb8007d8a57b792d7a23020edb0c74fbf4237
Separate the functionality of I4X4_PRED from decode_mb. Use
decode_atom_intra instead, to enable recursive partition of superblock
down to 8x8.
Change-Id: Ifc89a3be82225398954169d0a839abdbbfd8ca3b
Updates the tokenizer to use the common block walker used by the
detokenizer, to support non-4:2:0 and more than 3 planes.
Change-Id: If1854117a9c7c1427349209fa2b3051ce6459dcb
This doesn't change output, because the argument isn't actually used
ATM. However, we should fix it for consistency.
Change-Id: I7b7326a8e92c0d411c999ec2c781204b516ed53d
Unify the tokenize_ function and enable configurable block size for
superblock 8x8. We are immigrating the functionalities of
macroblock handles into superblock ones, and eventually will remove
encode_mb and decode_mb. To be continued on detokenize_ module.
Change-Id: I9f81e8c2291082535cf5e0c4b662eb24fb7c8a7f
Output changes slightly because of a minor bug in (at least) the sb32x16
block2above tx16x16 tables that previously existed in vp9_blockd.c.

All members can be referenced from their per-plane counterparts, and
removes assumptions about 24 blocks per macroblock.

The previous commit 15255ee "Move dequant from BLOCKD to per-plane MACROBLOCKD"
removed the vp9_asm_enc_offsets.c file, but didn't update the various secondary
build systems that special case these files. Restore it for now, to ensure any
in-progress changes and builds continue working, to allow time to more carefully
coordinate removal of these files.

This originally was "Removed update_blockd_bmi()". Now,
this patch removed bmi from blockd and uses the bmi found
in mode_info_context. Eliminates unnecessary bmi copies between
blockd and mode_info_context.

vp9_dequantize_x86 has only sse2 functions.
vp9_dct_sse2_intrinsics has no namespace collision and can drop
_intrinsics.
vp9_idct_mmx.h is unused.

Basic assumption: when talking about transform units, use b_; when
talking about macroblock indices, use mb_.
