eaaa2d27d5 fix CUDA LUT implementation 
In CUDA 6.0 there was a bug in NPP LUT implementation (invalid results when
src == 255). In CUDA 6.5 the bug was fixed.

Replaced NPP LUT call with own implementation (ported from master branch) 
to be independant from CUDA Toolkit version.

2c38be079e Enabled CV_Assert and such to print the function name with Visual C++. 
Also, I made a separate macro for the current function name, which
helps simplify a lot of code that uses it.

bff0fad6c3 gpu TVL1 Optical Flow optimization: 
do not calculate sum of error in every round of iteration;
instead the error will be summed every 2nd times or more, 
if the previous sum of error is too far away from threshold.
