* remove old BUILD_opencv_java option

* replace old build_java option with new BUILD_JAVA option

* issue 5769 fixed: cv::stereoRectify fails if given inliers mask of type vector<uchar>

* issue5769 fix using reshape and add regression test

* regression test with outlier detection, testing vector and mat data

* Size comparision of wrong vector within CV_Assert in regression test corrected

* cleanup test code

ISA 2.07 (aka POWER8) effectively extended the expanding multiply
operation to word types. The altivec intrinsics prior to gcc 8 did
not get the update.

Workaround this deficiency similar to other fixes.

This was exposed by commit 33fb253a
which leverages the int -> dword expanding multiply.

This fixes Issue #15506

* Added mechanism to set/toggle NORMAL window to TOPMOST window.

* highgui: remove unnecessary/legacy code

* Adding all possible data type interactions to the perf tests since some
use SIMD acceleration and others do not.

* Disabling full tests by default.

* Giving proper names, removing magic numbers and sanity checks of new
performance tests for the integral function.

* Giving proper names, making array static.

* fix 'chmod' is not recognized as an internal or external command in Windows
