fixed the type inconsistent with document.
...
Document say probs will have CV_64F type. But in effect, it has CV_32F type.

- LogisticRegressionImpl::predict() was changed to return the predicted value and to only write to the OutputArray results if specified (no longer segfaults).
...
- Refactored batch and mini_batch training to use a common gradient computation function (removed duplicate code).
- Altered the cost computation so that NAN is not computed unnecessarily.
- Greatly simplified (and sped up) the code that appends a column of 1s to the data.
- Minor code cleanup.
Removed unused variables.

fix randMVNormal in ML ( #5469 )
...
Fix the failed assertion by replacing the GEMM call.
Also random numbers are generated from normal distribution ~N(0,1),
instead of uniform distribution ~U(0,1).

Update em.cpp
...
Fix a bug. When reading from a saved model, function decomposeCovs() will be called. And if covMatType is COV_MAT_DIAGONAL, covsEigenValues is computed using SVD and eigen values are sorted so that the order of eigen values is not preserved. This would lead to different result when calling function predict2. This issues is discussed here: http://stackoverflow.com/questions/23485982/got-different-empredict-results-after-emread-saved-model-in-opencv .
