The encoding time for bus at CIF goes from 661s to 625s. This commit
also enabled unit test of sad8x4/4x8 in sad_test.cc.

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.

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.

100 frames run:
yt 0.138%

Adds a marker bit to allow distinguishing the frame header from its residual
data.

Change-Id: Id75d47acc9e5a97007e4690c4f8748a4ce63e641

This avoids encoding tokens for blocks that are entirely
in the UMV border. This changes the bitstream.

This patch eliminates the intermediate diff buffer usage by
combining the short idct and the add residual into one function.
The encoder can use the same code as well.

Code was previously using VPX_IMG_FMT_VPXI420, which was intended to be the
"vpx" non-YUV colorspace variant.

Disables the part of the error-resilient test that tests the
quality after dropping undroppable frames. It's not clear how
to set the threshold for this correctly at the moment.

Change-Id: I3ee4a0d475498f44711fdef05749f305e8d08591

This reverts commit b24735c6
since the adjusted threshold doesn't allow the existing tests
to pass. Will disable the failing test in a separate commit.

Note that the pass fail criteria for this test seems a bit
arbitrary to me.

input_ is filled with random values just afterward.
the size was wrong anyway as input_ is allocated with memalign so
sizeof(input_)==sizeof(uint8_t*)

Updates the common convoloution code to support blocks larger than
16x16, and rectangular blocks. This uncovered a bug in the SSSE3
filtering routines due to the order of application of saturation.
This commit fixes that bug, adjusts the unit test to bias its
random values towards the extremes, and adds a test to ensure that
all filters conform to the expected pairwise addition structure.

The superframe index marker byte carries data in the lower 5 bits. Only the
upper 3 should be used as part of the mask to detect it. By masking with
0xf0, the previous code was incorrect for frames over 65k bytes.

Improved coding performance made this test fail. Adjust the threshold
so that it passes again. A more stable metric is an open TODO.

A 'superframe' is a group of frames that share the same PTS, but have a
defined decoding order. This commit adds the ability to append an index
to such a group of frames, allowing for random access to the constituent
frames. This could be useful for frame-level parallelism or partial
decoding in a multilayer scenario.

Decoding the stream serially without such an index should work as a
fallback, and VP9/TestSuperframeIndexIsOptional verifies that.

Since the 8-tap lowpass filter is non-interpolating, the results are
different between applying it at whole-pel values and not. This
means that 1D-only versions are requried to be implemented, as
opposed to being an optimization of the 2D case. Calling the 2D
filter instead of the horizontal-only filter is not equivalent
in this case. Update the test to pass invalid filters to the
unused stage of the 1D-only calls, to verify they're unused.

Change-Id: Idc1c490f059adadd4cc80dbe770c1ccefe628b0a

Updates the convolve test to verify that all filters match the
reference implementation. This verifies commit 30f866f4, which
fixed some problems with the SSE3 version of the filters for
the vp9_sub_pel_filters_8s and vp9_sub_pel_filters_8lp banks
due to overflow and order of operations.

Change-Id: I6b5fe1a41bc20062e2e64633b1355ae58c9c592c

Fixes a bug in vp9_set_internal_size() that prevented returning to
the unscaled state. Updated the ResizeInternalTest to scale both
down and up. Added a check that all frames are within 2.5% of the
quality of the initial keyframe.

Change-Id: I3b7ef17cdac144ed05b9148dce6badfa75cff5c8

This avoids duplicating all the filters twice. Includes fixups to the
convolve routines and associated tests to make this work.
