glibc defines major and minor macros
which conflict with  gpu::DeviceInfo methods with the same name

now DeviceInfo provides full information about device (from cudaDeviceProp)

- fixed printCudaDeviceInfo for new CC
- fixed some compilation errors and warnings
- removed unset command from CMake script
- removed unused std imports

fixed bug in opencv_stitching (corrected resize images step), added matches checking (both 1->2 and 2->1 must be presented)
