Change-Id: I916afec61b3019f18193135dac7c35ed0f89b8b6

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.

This commit enables configurable reference buffer pointer for intra
predictor. This allows later removal of spatial dependency between
blocks inside a 64x64 superblock in the rate-distortion optimization
loop.

Change-Id: I26bf6bb90de342a3036c0dbfba78a7dd75a61fe7

All elements of this table are equal to 252, so replace it with a
single constant VP9_COEF_UPDATE_PROB.

Change-Id: I1e2d1d284326ce6df9899a740c2fc344b3ec81c9

Avoid calling decode_block, inverse transform/add in the block is
a skip block for SBs smaller than 8x8 and intra-coded SBs.

A corrupt bitstream could refer to a reference frame that has no size.

Previous code indexed using the tile length coded in the bitstream
without checking that the read would be valid.

Change-Id: Ia5047762223a4f80d75016dd546dc2ef18b6887d

Removes the case of coding prob = 0 for forward updates, since that
is not an allowed probability to code.
Slightly improves efficiency but may not matter in practice.

Change-Id: I3b4caf82e8f0891992f0706d4089cc5a27568dba

* 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

This is consistent with uncompressed header encoding.

Change-Id: Iccf40a44b493ed36ee085b81ed56f7952cde70a9

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

Change-Id: I32311367812faf37863131df3af37d63d03973d7

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

For key frames everything is the same as before. For inter frames we try
to reference last/golden/altref frame size. If there is no match then the
actual size is encoded. Also we don't allow zero width and height anymore.

Change-Id: I49d791fd94af749c823579b0c5ef17c961372678

Made changes to the frame header to write the sync
code in the frame header for a non-displayable,
intra-only frame.

Extended reset_frame_context to 2-bits.

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.

Change-Id: I6a7af099f6ad61d448521d9a51167aedaf638ed6

Refactors mbskip coding to be compatible with coding of the rest of

the legacy code.
