IPP_VERSION_X100 was changed to:
...
IPP_VERSION_MAJOR * 100 + IPP_VERSION_MINOR*10 + IPP_VERSION_UPDATE
to manage changes between updates more easily.
IPP_DISABLE_BLOCK was added to ease tracking of disabled IPP functions;

Some changes to support mingw-w64
...
- IPP is disabled by default when compiler is mingw (couldn't make it
work)
- fixed some warnings
- fixed some `__GNUC__` version checks (for correctness and convenience)
- removed UTF-8 BOM from hough.cpp (fixes #5253 )

Removed check on limits. A common use of HoughLines would be to restrict theta to be between a small negative number and a small positive number, e.g. -pi/16 to pi/16. This wasn't possible with the previous checks.

Updated Documentation (HoughCircles)
...
Rewrite the note on HoughCircles documentation to make it more clear
Add note to clarify that the output vector of found circles is sorted by
descending order of centres accumulator values.
Also delete reductant lines on the HoughCircles documentation.
Added comments to hough circles function.
Added comments to icvhoughgradient
Misalignment in line 1183 corrected

Implementation detector and selector for IPP and OpenCL;
...
IPP can be switched on and off on runtime;
Optional implementation collector was added (switched off by default in CMake). Gathers data of implementation used in functions and report this info through performance TS;
TS modifications for implementations control;
