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.

If a reference frame is inter, the only valid modes would
be inter modes. This check is unnecessary.

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.

The decode_mb only carries I8X8_PRED decoding, which will be covered
by the regular MB intra modes when SB8X8 is on. To be removed later.

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.

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.

Also fixed two minor subtle boundary conditions in intra prediction
code, and replaced memcpy/memset with vpx_ prefixed version.

The commmit changed to use same intra prediction function for all
block sizes.
Some details on the changes:
1. All directional modes except DC/TM/V/H now have built-in filtering
for all pixels with filter taps either (1, 2, 1)/4 or (1, 1)/2.
2. Above edge get automatic extended to double width (bw*2), which
makes a lot of the prediciton mode computation simpler.
3. Same intra prediction function is called with different size
for i4x4_pred and all other larger size.
Overall, the change helped keyframe only coding for both cif size
and std-hd size test sets by .5% consistently on all encodings.
For normal coding with single/auto key frame, the change now also
is consistently net positive for all encodings. The overall gains
is about .15% on std-hd set.

Updates the tokenizer to use the common block walker used by the
detokenizer, to support non-4:2:0 and more than 3 planes.

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.

Output changes slightly because of a minor bug in (at least) the sb32x16
block2above tx16x16 tables that previously existed in vp9_blockd.c.

Turns model based reverse updates on for coefficients in an
effort to reduce the memory requirement for counters.
With this patch the counters needed will be reduced by about
75% since only 3 counts are needed instead of 12.
The impact in performance is:
derf300: -0.252%
stdhd250: -0.046%
However retraining should alleviate some of the drop in
performance.

First patch to make sb decoding based on the transform size. This patch
is working for the sb modes, combining the parts of decode_mb that fit
into this framework will come as a second patch.

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.
