411fd2b761 Add Thickness parameter in drawMatches function
This commit adds the feature of selecting the thickness
of the matches drawn by the drawMatches function.

In larger images, the default thickness of 1 pixel creates images
that are hard to visualize.

(cherry picked from commit 4a8f06755c)

* Added response to GFTT Detector keypoints

(cherry picked from commit b88fb40c6e)

* Moved corner values to another optional variable to preserve backward compatibility

(cherry picked from commit 6137383d32)

* Removed corners valus from perf tests and better unit tests for corners values

(cherry picked from commit f3d0ef21a7)

* Fixed detector gftt call

(cherry picked from commit be2975553b)

* Restored test_cornerEigenValsVecs

(cherry picked from commit ea3e11811f)

* 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

Merge pull request #17735 from pemmanuelviel:pev-fix-trees-descent
* Fix trees parsing behavior in hierarchical_clustering_index:
Before, when maxCheck was reached in the first descent of a tree, time was still wasted parsing
the next trees till their best leaf, just to skip the points stored there.
Now we can choose either to keep this behavior, and so we skip parsing other trees after reaching
maxCheck, or we choose to do one descent in each tree, even if in one tree we reach maxCheck.

* Apply the same change to kdtree.
As each leaf contains only 1 point (unlike hierarchical_clustering), difference is visible if trees > maxCheck

* Add the new explore_all_trees parameters to miniflann

* Adapt the FlannBasedMatcher read_write test to the additional search parameter

* Adapt java tests to the additional parameter in SearchParams

* Fix the ABI dumps failure on SearchParams interface change

* Support of ctor calling another ctor of the class is only fully supported from C+11
