This commit limits the scope of 1-D DCT and ADST functions within
vp9_dct.c and makes them static. This largely clears out the cross
referencing issue between vp9_dct.c and the SIMD optimizations.

The SSE2 version high bit-depth forward hybrid transforms are
essentially using the C functions via cross referencing to 1-D
functions in vp9_dct.c. This commit unifies the two versions and
removes the unnecessary dependency.
Change-Id: Ib4d0702a138f8daf7d0bd97c141ee7088f293765
Separate the hybrid transform case from 2D-DCT case. This will
allow us to clear up cross dependency between c and SIMD
implementations later.

The following quantization functions were moved:
vp9_quantize_b
vp9_quantize_b_32x32
vp9_highbd_quantize_b
vp9_highbd_quantize_b_32x32
vp9_quantize_dc
vp9_quantize_dc_32x32
vp9_highbd_quantize_dc
vp9_highbd_quantize_dc_32x32
The purpose of doing that was to allow these functions to be shared
by multiple codecs.

This commit moves the loop filter dspr2 implementation from vp9 to
vpx_dsp directory. It also fixes header file format issues.

Remove the use of drop_frames_water_mark, as this is used for
frame dropping control. Use fixed threshold for now on buffer underflow.

For vp9 decoder build without profile 2 and profile 3 support, this
commit changes to report error "Unsupported bitstream profile" for
input streams in profile 2 or 3, rather than other misleading error
information.
In addition, one of the invalid files in unit tests is actually coded
profile 2, this commit makes it tested only when the decoder is built
with vp9-highbitdepth.
This fixes issue #1028.

The various tap loop filter operations are common functions across
codec. This commit moves them along with SIMD optimizations to
vpx_dsp folder.

In aq-mode=3 under a resizing action (i.e., resize_pending != 0),
force an update of the golden reference frame.

Fix bug in setting this flag for animated content.
The bug did cause quality to increase because far
more frames are not boosted than boosted.
However, the speed trade off to gain is a lot less
favorable and the behavior was not as intended.
Change-Id: I89fb70419c88b26f40b3534de0481730a1b3fcfa
Move the clamp functions to vpx_dsp_common.h file. Clear out the
dependency of vp9_loopfilter_filters.c on vp9_common.h file.

Use drop_frames_water_mark for threshold on buffer underflow,
and change threshold for resize down.
Change-Id: I2de19adce50abe9bcdc0b107528cec8cc1857fcc
The fast scaling for 1 pass mode was being used only on the
first frame after resizing event (because resize_scale_num/den
is set to 1 and only changed for first frame following resize event).
Change-Id: I723b63e21823eb858f25f5662d2bbe4f1842e61f
Proper use/update of resize_state and resize_pending to constrain
the total amount of downsizing to be at most one scale down, for now.

There is still an issue relating to one animated test clip with repeat
patterns where this change effectively increase the default maximum
arf interval by +1. This can be examined seperately.

Flaten the intra block decoding process. It removes the legacy
foreach_transformed_block use in the decoder. This saves cycles
spent on retrieving the transform block position.

This commit simplifies the intra block boundary condition logic.
It removes the block index from the argument set.

Eliminates the byte by byte read from bool decoder, by reading
in a size_t and then shifting it into place.

The clamp calls with INT32_MIN and INT32_MAX have no effect at all on
int values passed in, therefore this commit removes those effectless
clamps and also adds more const intermediate results to make the code
more readable.

Rework the inter mode transform block decoding loop. Replace the
block index with the row and col index as the input argument. It
saves function call to compute the row and col index according to
the block index and overall block size, and many if statements
associated with the transform block position relative to the coding
block. For the test bit-stream pedestrian_area 1080p at 5 Mbps,
the decoding speed goes up from 81.13 fps to 81.92 fps.
Note that the intra coded block decoding needs more refactoring
work than the inter ones. So keep it using foreach_transforme_block
as for now.

The encoder gets its dqcoeff from the context tree. In the decoder move
it to directly after MACROBLOCKD.

Even if the recode loop is not enabled for the current frame type
trap the case where the projected size of a a frame is above the
maximum allowed in recode_loop_test()

Changes to allow more use of rectangular partitions at
speeds 1 and 2 for content classed by the first pass as
animation and for blocks near the active image edge.
This has quite a big impact in quality for the animated
test sequence but also hurts encode speed for speed 2.
For other content types the impact on both speed and
quality is small.
Added some plumbing for detection of internal vertical
image edges.
Change-Id: I3fc48de2349f8cb87946caaf0b06dbb0ea261a9a
Change speed features / behavior for split mode when there
is an internal active edge (e.g. formatting bars).
Remove some threshold constraints in rd code near the active
edge of the image.
Add some plumbing for left and right active edge detection.
Patch set 5. Limit rd pass through for sub 8x8 to internal active edges.
This takes away any speed penalty for most clips but keeps the enhanced
edge coding for the more critical case of internal image edges

Replace block index with transform type in the argument list. This
allows to save an extra fetch to the prediction mode. For pedestrian
area 1080p coded at 5 Mbps with single tile, the average decoding
speed goes up from 80.55 fps (before the refactoring series) to
81.13 fps.

If the pre-selected partition size (from variance partition) is
32x32, also apply nonrd partition search for 32x32 and 16x16 size.
Overall small positive gain in metrics, average ~1%.
Some visual improvement, for lower resolutions.

The decoding process handles detokenization and reconstruction per
transform block sequentially. There is no need to offset the dqcoeff
buffer according to the transform block index. This allows to
reduce the memory spill and improve cache performance.
Change-Id: Ibb8bfe532a7a08fcabaf6d42cbec1e986901d32d
inline the code directly in read_mv_component(), the only place where it
was being used; this removes a function call in a hot function
