* goodFeaturesToTrack returns also corner value
(cherry picked from commit 4a8f06755cf93785a82a455a2035a2ff572cafae)
* Added response to GFTT Detector keypoints
(cherry picked from commit b88fb40c6ea037e5283e4fbcf0ffde160c65a035)
* Moved corner values to another optional variable to preserve backward compatibility
(cherry picked from commit 6137383d32859efad7b44dd8a798e7b69f68dec5)
* Removed corners valus from perf tests and better unit tests for corners values
(cherry picked from commit f3d0ef21a78b7d0dc8696c457a6fabecfbe5e8ff)
* Fixed detector gftt call
(cherry picked from commit be2975553ba01a7d2e63f549fadccec6d7d56797)
* Restored test_cornerEigenValsVecs
(cherry picked from commit ea3e11811faee63487449983c0b80ff8ee35bbac)
* scaling fixed;
mineigen calculation rolled back;
gftt function overload added (with quality parameter);
perf tests were added for the new api function;
external bindings were added for the function (with different alias);
fixed issues with composition of the output array of the new function (e.g. as requested in comments) ;
added sanity checks in the perf tests;
removed C API changes.
* minor change to GFTTDetector::detect
* substitute ts->printf with EXPECT_LE
* avoid re-allocations

double area = moms.m00;
is same as
double area = contourArea(contours[contourIdx]);
Not to mention
"moms" already calculated here,"contourArea" should not apply
Build DoG Pyramid if useProvideKeypoints is false
The buildDoGPyramid operation need not be performed unconditionally. In cases where it is not needed, both memory and speed performance can be improved
