08a453b9de Replace vp9_ prefix with vpx_ prefix in vpx_dsp function names
This commit clears the function naming convention in vpx_dsp. It
replaces vp9_ prefix of global functions with vpx_ prefix. It also
removes the vp9_ prefix from static functions.

e253eaa036 Unify the high bit-depth forward hybrid transforms
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.

fd3658b0e4 replace DECLARE_ALIGNED_ARRAY w/DECLARE_ALIGNED
this macro was used inconsistently and only differs in behavior from
DECLARE_ALIGNED when an alignment attribute is unavailable. this macro
is used with calls to assembly, while generic c-code doesn't rely on it,
so in a c-only build without an alignment attribute the code will
function as expected.

d50716face Incorporate WRAPLOW macro into non-highbitdepth tx
Incorporates the WRAPLOW macro into the non-highbitdepth transforms
to aid hardware verification between a software C model and an
intended hardware implementation though the use of the configure
options: --enable-experimental --enable-emulate-hardware.
Note that to avoid further discrepancies between the sse/sse2
implementations of the transforms and the C implementation, when the
emulate hardware option is invoked, we also disable sse/sse2/etc.

Also incudes some minor cleanups/renaming etc.

10783d4f3a Adds high bitdepth transform functions and tests
Adds various high bitdepth transform functions and tests.
Much of the changes are related to using typedefs tran_low_t
and tran_high_t for the final transform cofficients and intermediate
stages of the transform computation respectively rather than fixed
types int16_t/int. When vp9_highbitdepth configure flag is off,
these map tp int16_t/int32_t, but when the flag is on, they map
to int32_t/int64_t to make space for needed extra precision.

5c2696c378 Rework unit test for 8x8 transformation
This commit reworks the unit test for 8x8 forward/inverse
transformation. It adds extreme input value test to detect overflow
issues in the intermediate steps.

It temporarily disables unit test for the SSSE3 version, which
showed overflow failure in the new test conditions.

3a0602578e Giving consistent names to IDCT/IWHT functions.
The idea is to have the following names for each transform size:

vp9_idct4x4_add
  vp9_idct4x4_1_add
  vp9_idct4x4_10_add
  vp9_idct4x4_16_add

vp9_idct8x8_add
  vp9_idct8x8_1_add
  vp9_idct8x8_10_add
  vp9_idct8x8_64_add

etc for 16x16, 32x32

The actual list of renames in this patch:

vp9_idct_add_lossless     -> vp9_iwht4x4_add
vp9_short_iwalsh4x4_add   -> vp9_iwht4x4_16_add
vp9_short_iwalsh4x4_1_add -> vp9_iwht4x4_1_add

vp9_idct_add            -> vp9_idct4x4_add

vp9_short_idct4x4_1_add -> vp9_idct4x4_1_add
