Switch to CuDNN v5
...
For batch normalization, running inverse standard deviation becomes
running variance. We mirror this CuDNN v5 change in the CNTK batch
normalization engine. Model version is bumped. When old models are
loaded, this parameter is (approximately) converted.
In the same model version change, let batch normalization count
samples seen rather minibatches (this deals with incorrect averaging
when minibatch size is varied across epochs).
For batch normalization averaging and blending handle initialization
cases, don't rely on mean and variance initial values (set in
NDL/BrainScript).
Update Windows / Linux / Docker build.
With this commit, CuDNN v4 is not supported anymore.
