bc484ebf06 fix unit test failure on win32 vs2008 build
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.

ab362621fe Add 8x8 dct/adst unit tests
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.

794a7bedbd WIP: 8x8 idct/recon merge
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.

c4195e0eb8 tests: use a portable rand() implementation
the one from gtest in this case: testing::internal::Random.
this will make the tests deterministic between platforms. addresses
issue #568.

22012ee994 optimize 8x8 fdct rounding for accuracy
The commit added a final rounding choice for 8x8 forward dct to get
rid of a sign bias at DC position and improve the accuracry in term
of round trip error for 8x8 fDCT/iDCT.

This commit also enabled forward 8x8 dct test.

510557e2eb removed the idct rtcd idct calls
More cleanup to do after this,  but this is a good chunk of removing rtcd.

s/([vV][pP])8/$19/
additionally dct.h was removed; declare the _c functions that are used
in the tests. the TODO for conversion to parameterized tests still
remains.

95ee7f1131 change to properly account for coef scaling in unit tests
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.
