5169c79978 fix medianBlur accessviolation
medianBlur called with "empty" source and ksize >= 7 crashes application with accessviolation. With this extra assert this is avoided and the application may normally catch the thrown exception.

be7d060ea4 Merge pull request #7802 from terfendail:ovxhal_wrappers_migration
* OpenVX HAL updated to use generic OpenVX wrappers

* vxErr class from OpenVX HAL replaced with ivx::WrapperError

* reduced usage of vxImage class from OpenVX HAL replaced with ivx::Image

* vxImage class rewritten as ivx::Image subclass that calls swapHandle prior release

* Fix OpenVX HAL build

* Fix for review comments

396921dd23 5x5 gaussian blur optimization
Add new 5x5 gaussian blur kernel for CV_8UC1 format,
it is 50% ~ 70% faster than current ocl kernel in the perf test.

349d5ba012 --perf_instrument parameter now has int type and 0, 1, 2 modes (1 - simple trees, 2 - expanded trees for functions with same name but different calling address);
Maximum depth limit var was added to the instrumentation structure;

Trace names output console output fix: improper tree formatting could happen;
Output in case of error was added;

Custom regions improvements;

Improved timing and weight calculation for parallel regions; New TC (threads counter) value to indicate how many different threads accessed particular node;

parallel_for, warnings fixes and ReturnAddress code from Alexander Alekhin;

3607da9f6b ocl kernel performance optimization for box filter
The optimization is for CV_8UC1 format and 3x3 box filter,
it is 15%~87% faster than current ocl kernel with below perf test

./modules/ts/misc/run.py -t imgproc --gtest_filter=OCL_BlurFixture*

Also add test cases for this ocl kernel.

cc903d0605 Fix for #5590. OpenCL BilateralFilter implementation failes to
build for some OCL drivers.
Some OCL vendors treat implicit scalar-vector conversions for
operators as errors when type conversion is required.

a5a21019b2 ipp_countNonZero build fix;
Removed IPP port for tiny arithm.cpp functions

Additional warnings fix on various platforms.

Build without OPENCL and GCC warnings fixed

Fixed warnings, trailing spaces and removed unused secure_cpy.

IPP code refactored.

IPP code path  implemented as separate static functions to simplify future work with IPP code and make it more readable.
