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.

This changeset allows to remove vp9_switchable_interp and
vp9_switchable_interp_map arrays and make code much clear. Actually we
still have to use these mapping but only inside read_interp_filter_type and
write_interp_filter_type functions.
Change-Id: I4026c6f8c4acefba6c81421b7bacbaa52cc45f50
Adding common merge_probs and merge_probs2 functions. Changing ints to
usigned ints in some places.
Change-Id: Icf088ffdea7cf5b95284a128916409bdd53506b0
Counts are separate from frame context. We have several frame contexts but
need only one copy of all counts.
Change-Id: I5279b0321cb450bbea7049adaa9275306a7cef7d
All filters are interpolating now, so we don't need this array, all
values from this array are evaluated to true.
Change-Id: I9af6d8219ae0eb984063cd15e4e2296374ae4961
Update logic for both mode and mvref was the same, so using MODE_COUNT_SAT,
MODE_MAX_UPDATE_FACTOR, update_ct, update_ct2 for both cases. Removing
function update_tx_ct because it was identical to update_mode_ct2.
Change-Id: Iff566be27dbd6cde4c2ec04e8d988f207046b8f0
Adding loopfilter struct with fields from MACROBLOCKD and VP9Common.
Eventually it will be moved to vp9_loopfilter.h for better code structure.
Change-Id: Iaf5fb71c33719cdfa1b991f671caf071be9ea035
Changing fc->tx_probs back to fc->pre_tx_probs. This change actually
affects the bitstream but current test vectors work. Chrome branch is not
affected at all. Broken since:
cc662dd Adding struct tx_probs and struct tx_counts to cleanup the code.
Change-Id: I36dd4b3678e902e10aba8dd49b0012eb558c209d
Renaming vp9_sb_mv_ref_tree to vp9_inter_mode_tree, and
vp9_sb_mv_ref_encoding_array to vp9_inter_mode_encodings.
Change-Id: I0e91fbf81350d3ec5a2599064c74089b5d06133a
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.
Change-Id: Ia16b38b46aec2e2500f5df29c40a297ae241dede
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.
Change-Id: I23fabc33f11a359249f5f80d161daf569d02ec03
Using vp9_set_pred_flag function instead of custom code, adding
decode_tokens function which is now called from decode_atom,
decode_sb_intra, and decode_sb.
Change-Id: Ie163a7106c0241099da9c5fe03069bd71f9d9ff8
* New probs for subpel filters/tx_count
* Makes a change to not reset to defaults for the tx_size
probs if an intermediate frame reverts to using a fixed tx_size.
* A few updates to the parameters for backward adaptation for mode/mv
* some cosmetic cleanups

No bitstream change.
Removes unused filters and the code for the case of 2 switchable filters;
also changes the 8tap-smooth filter coefficients for integer shifts to be
interpolating to be consistent with the way it is implemented currently.
Change-Id: I96c542fd8c06f4e0df507a645976f58e6de92aae
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
Change-Id: I17656bd6db76224ae2856adf882504560e7dbaa4
Adds coding of transform size within a frame by use of context
of transform sizes selected in left and above blocks.
Also incorporates code for generating stats.
TODO: generate and incorporate new default stats
Change-Id: I6a7af099f6ad61d448521d9a51167aedaf638ed6
Refactors mbskip coding to be compatible with coding of the rest of
the symbols. Adds forward/backward adaptation and removes a lot of
the legacy code.

Change-Id: I395a2976d15af044d3b8ded5acfa45f6f065f980
With the removal of i4X4 and SPLIT_MV modes, the two entries for the
modes are no longer used. This patch remove the coding of the deltas.
Change-Id: Iea4eb500404ebe9706159380a03b8eca542fb4c3
Changes to the coding of transform sizes, along with forward
and backward probability updates.
Results:
derf300: +0.241%
Context based coding of transform sizes will be in a separate
patch.
Change-Id: I97241d60a926f014fee2de21fa4446ca56495756
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.
Change-Id: I4639a78cd5cccb283023265dbcc07898c3e7cf95
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.
Change-Id: I77ca996e25e4a28e03bdbc542f27a3e64ca1234f
Adds backward adaptation and differential forward updates of switchable
interpolation filter probabilities. Also adds some cosmetic cleanups
and minor fixes on mv_ref probabilities.
derfraw300: +0.353% (with most coming from switchable interp changes)
