[AMVRES=1 (QC_AMVRES macro = 1), QC_AMVRES_LOW_COMPLEXTY macro = 0]

5/8th position of 12-tap DCT-IF filter is strange: (it should be symmetric values to 3/8th position)

Here is the changes:

Current 3/8:

{ -3, 9, -15, 27, -51, 200, 119, -44, 24, -14, 7, -3 }, 3/8

Current 5/8:

{ -1, 6, -12, 20, -40, 119, 195, -44, 22, -14, 6, -1 }, 5/8

Fixed 5/8: (symmetric to 3/8)

{ -3, 7, -14, 24, -44, 119, 200, -51, 27, -15, 9, -3 }, 5/8

Fortunately, default value of QC_AMVRES_LOW_COMPLEXTY = 1, so no performance change in default setting with this change.

As reported by Xiang Li: "We have a minor memory leak with the edge tool. In tcomprediction.cpp line 100, EdgeBasedPred is never released".

As a MDDT tester in TE12, we found the following problem:

TMuC VLC encodes first 64 coefficients of transformed residual in intra (after TMuC 0.5), but when MDDT is turned off, interleaved coding of TMuC 0.1 is used.

Furthermore, we found that turning off MDDT disables RDOQ in intra modes.

It should be changed as: (1) enabling RDOQ when MDDT=0 (2) same coding method (first 64 coefficients) for MDDT=0 and 1.

It affects two tests (low-complexity configuration only) in TE12: (1) MDDT-off test (2) MDDT-off + ROT-off combination test.

Patch can be applied for this without affecting all other tests in TE12.
