This setup is now handled by vp9_build_intra_predictors()
when left_available and/or up_available is zero.

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.

This commit enables bit-stream writing and reading for recursive
partition down to block 8x8.

Change-Id: I163cd48d191cc94ead49cbb7fc91374f6bf204e2

transform sizes.

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

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.

Change-Id: I70c5bfbaa1c8bf00fde0bfc459d077f88b6d46c8

Moving common code from encoder and decoder to vp9_update_frame_size.

Change-Id: I6ca758b7d05ffd52821bd3f7ad68089da11e4165

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

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

Change-Id: I624af28ac200a8322d64454cf05c79e9502968cc

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.

Change-Id: I7ff2fa72d22c29163eb558981c8193765a8113d9

Access these members from MACROBLOCKD instead.

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.

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

Change-Id: Ifd163f595d4924ff892de4eb0401ccd56dc81884

The quantizer can vary per-plane, and the dequantization vector is
available in the per-plane part of MACROBLOCKD. The previous code would
incorrectly use the Y quantizer for the whole macroblock.

Change-Id: I3ab418aef9168ea0ddcfa4b7c0be32ae48b536d7

This data can vary per-plane, but not per-block.

memcpy with plain struct assignment.

Function set_mb_row() and set_mb_col() do similar work and are always
called together, this commit merged them into a single function for
clarity and easy maintainence.  This was a TODO item.

Move rectangular superblock coding out of experimental list.

Change-Id: I96c37547d122330d666a67b4bf577ae54547857f

This commit enables selecting probability models for recursive block
partition information syntax, depending on its above/left partition
information, as well as the current block size. These conditional
probability models are reasonably stationary and consistent across
frames, hence the backward adaptive approach is used to maintain and
update the contextual models.

It achieves coding performance gains (on top of enabling rectangular
block sizes):
derf:   0.242%
yt:     0.391%
hd:     0.376%
stdhd:  0.645%

Also some further simplification following removal
of top node code.

There is an issue in regards to the shared file vp8cx.h
in regard to the roi_map as this interface assumes that
there are only 4 segments. I have left the value here as
4 for now meaning that the roi_map interface is broken
for VP9.

Note that this change would have been easier if I hadn't
had to search for hard wire instances of the number 4
and <= 3.

Change-Id: Ia8b6deea4be4dbd20deb1656e689dd43a5f190e8

Remove top node optimization.
The improvement this gives is not sufficient to justify
the extra complexity.
