Adding CHECK_MEM_ERROR macro to vp9_common.h and removing two duplicated
ones from vp9_onyx_int.h and vp9_onyxd_int.h.

Also tweaks to other features and experiments with
what is on and off at different speed settings.

All elements of this table are equal to 252, so replace it with a
single constant VP9_COEF_UPDATE_PROB.
Change-Id: I1e2d1d284326ce6df9899a740c2fc344b3ec81c9
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.

* 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

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

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.
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.

The partition types of blocks sitting on the frame boundary are
constrained by the block size and the position of each sub-block
relative to the frame. Hence we use truncated probability models
to handle the coding of such information.

Just an intermediate change set to simplify merges. Reordering several
uncompressed header bits, code restructuring + minor cleanups.
Change-Id: I28272f520762f8c4e3ad230ae39fff5102ba5c0d
Changes to the coding of transform sizes, along with forward
and backward probability updates.

Context based coding of transform sizes will be in a separate
patch.
Change-Id: I97241d60a926f014fee2de21fa4446ca56495756
Adds the ability to have the decoder show one of the existing reference
frames directly, without having to code it indirectly as a series of
skip blocks.
Change-Id: Ib6c26c5f6a8709863cf304ab890db8559687d25e
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.
