Trans4x4HT is disabled as the tests currently fail.
note not all functions have NEON implementations:
- fdct4x4/fht4x4

This commit enables the unit tests for 4x4 DCT and ADST transforms.
It covers tests of round-trip error check, coefficient match check,
coefficient overflow check, and inverse accuracy check.

For consistency with idct function names. Renames:
vp9_short_fdct4x4 -> vp9_fdct4x4
vp9_short_walsh4x4 -> vp9_fwht4x4

Just making fdct consistent with iht/idct/fht functions which all use
stride (# of elements) as input argument.

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

The mix use of double type and simd code caused invalid values stored
in double variables, further caused unit tests to fail. The failures
were only observed on x86-win32-vs9 build with vs2008.

comment out some unused parameters and adjust the format to avoid:

This commit enables 8x8 DCT and hybrid transform unit tests. It
also tunes the forward hybrid transform rounding opertions for
more precise round-trip performance.

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

additionally dct.h was removed; declare the _c functions that are used
in the tests. the TODO for conversion to parameterized tests still
remains.

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.
