Replace vp9_ in names to vpx_ as they are not codec specific.

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.

Separate the hybrid transform case from 2D-DCT case. This will
allow us to clear up cross dependency between c and SIMD
implementations later.

These files have been moved to vpx_dsp directory. Clean the
vp9_common make file accordingly.

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.

Change-Id: I09203ed4bd267d7fd76bb79a6ee84a37646206b2

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.

Narrow the scope of dependency required by the dspr2 implementation
of loop filters.

Narrow the scope of dependency in dspr2 loop filter implementation.

Change-Id: I30426d7e4d41575a82286f1d3c5881aeb99a3250

Move the common prefetch_load/store in dspr2 to header file in
vpx_dsp/mips.

The common_dspr2.h should be independent of codec-specific data
structures.

Change-Id: I34ee1f9552c2d2d205fd7f1813cdf312c7ff5d2b

The dependency on vp9_loopfilter.h is not needed.

Change-Id: Ic0583c43d3d63f19cef06cf9d8e5c8031601be6a

Remove the codec-specific global prefix from static function names.

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.
