- make green Linux debug/Linux32/Win32 builders

This avoids MSVC 19.14.26428.1 to call vectorized __vdecl_cosf4() function with less precision.

- allow 5% of changed pixels with intensity difference <= 1

  * let OpenCL kernel run only on Intel GPU
  * brush up the workaround based on 9a2b028 from alalek

resolves #11511

Pass --test_bigdata to allow launching of "BigData" tests.

* make sure that the matrix with more than INT_MAX elements is marked as non-continuous, and thus all the pixel-wise functions process it correctly (i.e. row-by-row, not as a single row, where integer overflow may occur when computing the total number of elements)

cuda_canny : multi stream safety (#11483)

* CUDA_ImgProc/Canny Asynchronous test

* cuda_canny : multi stream safety (1/3)

- Convert global variable canny::counter to class local variable

* cuda_canny : multi stream safety (2/3)

- Use texture objects rather than texture reference for cc >= 3.0,
  since texture reference must be declared as a static global variable
  which results in race condition when ran concurrently

* cuda_canny : multi stream safety (3/3)

- Refrain from using global variable in row_filter and column_filter
  (converts column_filter::c_kernel and row_filter::c_kernel to local
  variables)

* Fixes #11193

'0' is specific case (make no sence as a standalone operation),
but it can be useful in template-based programming.

with the ffmpeg backend

  * remove meaningless tests

* add v_float64x2 support to v_rotate_*
* treat float vector in v_check_any, vec_any_lt as int vector
* add test case for v_rotate_left

* FIX INF_ENGINE RELU ERROR

* set slope to variable
