mode_info_context was stored as a grid of MODE_INFO structs.
The grid now constists of pointers to MODE_INFO structs. The
MODE_INFO structs are now stored as a stream (decoder only),
eliminating unnecessary copies and is a little more cache
friendly.

mode_info_context was stored as a grid of MODE_INFO structs.
The grid now constists of a pointer to a MODE_INFO struct and
a "in the image" flag. The MODE_INFO structs are now stored
as a stream, eliminating unnecessary copies and is a little
more cache friendly.
For the test clips used, the decoder performance improved
by ~4.3% (1080p) and ~9.7% (720p).
Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p)
and 5.9% (720p).

VP9_COMMON is the right place to segmentatation struct because it has
global segmentation parameters, not something specific to macroblock
processing.
Change-Id: Ib9ada0c06c253996eb3b5f6cccf6a323fbbba708
Loop filter configuration doesn't belong to macroblock, so moving it from
MACROBLOCKD to VP9_COMMON. Also moving the declaration of loopfilter struct
from vp9_blockd.h to vp9_loopfilter.h.

Counts are separate from frame context. We have several frame contexts but
need only one copy of all counts.
Change-Id: I5279b0321cb450bbea7049adaa9275306a7cef7d
Adding loopfilter struct with fields from MACROBLOCKD and VP9Common.
Eventually it will be moved to vp9_loopfilter.h for better code structure.

these are only used in the encoder.

These arrays have constant values (no any updates). Removing two
corresponding memcpy calls. Making a little cleanup in vp9_entropymode.h
as well: removing redundant 'extern' keyword and moving all function
declarations at the end.

Removing tile_rows and tile_columns from VP9Common, removing redundant
constants MIN_TILE_WIDTH and MAX_TILE_WIDTH, changing signature of
vp9_get_tile_n_bits.

this was never fleshed out in the context of VP8, for which it was
added. for VP9 it has no meaning.
Change-Id: Iba2ecc026d9e947067b96690245d337e51e26eff
Adding segmentation struct to vp9_seg_common.h. Struct members are from
macroblockd and VP9Common structs. Moving segmentation related constants
and enums to vp9_seg_common.h.

Total encoding time for first 50 frames of bus (speed 0) @ 1500kbps
goes 2min34.8 to 2min14.4, i.e. a 10.4% overall speedup. The code is
x86-64 only, it needs some minor modifications to be 32bit compatible,
because it uses 15 xmm registers, whereas 32bit only has 8.

This commit fixed the allowable partition types for bottom-right
corner blocks.
When a block has over half of its pixels as valid content in both
vertical and horizontal directions, allow all the four partition
types in the bit-stream. Otherwise, apply partition type constraints.

Remove the bilinear filter mode, and the no-loopfilter mode, and the
related vp9_setup_version() function.

Implements ability to signal and decode frames that are
encoded using only intra coding modes. Only the decode
side has been implemented here.
Change-Id: I53ac6a8d90422cd08ba389e5236e15b45f9e93de
Reduces TX_SIZE contexts to 2 for each kind. The code is
cleaner and there is hardly any performance difference with
more than two contexts.
Results: almost neutral
