exercises the forward transforms
no idct/iht implementations, so the c-code is used

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.

This reverts commit 89fbf3de.

Trans4x4HT is disabled as the tests currently fail.

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.

Change-Id: I0ba3c52513a5fdd194f1e7e2901092671398985b

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

Change-Id: Ibca7a188fd062b196787ac5efc1ea545e7f166c0

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

test code.

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.

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.

The commit changed the name of files and function to remove obselete
reference to LLM and x8.

Change-Id: I973b20fc1a55149ed68b5408b3874768e6f88516

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

Change-Id: I566aeed9c7c34da5a206190aa7d0e847a4008b36

More cleanup to do after this,  but this is a good chunk of removing rtcd.

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.
