ones from vp9_onyx_int.h and vp9_onyxd_int.h.

Change-Id: I916afec61b3019f18193135dac7c35ed0f89b8b6

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

Change-Id: I3e1d0be0d195216bf17c2ac5df67f34ce0b306b2

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

Change-Id: I57be4eeaea6e4402f6a0cc04f5c6b7a5d9aedf9b

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

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.

Change-Id: Ie836ae0df9ed572fb4f08aabe9351a555c4f3b96

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.

Simplify feature to only support a single reference frame
instead of a mask.

Change-Id: I5dd3a98c7a224aafb35708850ab82e2f220e68fb

Just an intermediate change set to simplify merges. Reordering several
uncompressed header bits, code restructuring + minor cleanups.
