Also removes some spurious changes in common/vp9_blockd.h which
was introduced by a rebase issue between nextgen and master branches.

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.

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.

assembly functions.

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.

Includes changes that are not compatible with VS windows builds.
Amongst other things stdint.h is not supported in VS.

It covers tests of round-trip error check, coefficient match check,
coefficient overflow check, and inverse accuracy check.

Renames:
vp9_short_iht4x4_add -> vp9_iht4x4_16_add
vp9_short_iht8x8_add -> vp9_iht8x8_64_add
vp9_short_iht16x16_add_c -> vp9_iht16x16_256_add

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_add -> vp9_idct4x4_16_add
vp9_short_idct4x4_1_add -> vp9_idct4x4_1_add

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.

1. changed 4x4 test name to Vp9Fdct4x4Test to be consistent
2. remove forward 8x8 dct test code from idct8x8_test.cc
3. temporarily disable other forward dct tests to allow fdct work in
progress

The transform functions in experimental branch absorbed a scaling
factor of 4 to allow quantization steps closer to unit quantizer.
This commit added scaling code in between forward and inverse
transform to properly account for the scaling factor.
