Merge pull request #18019 from pemmanuelviel:pev--multiple-kmeans-trees
* Possibility to set more than one tree for the hierarchical KMeans (default is still 1 tree).

This particularly improves NN retrieval results with binary vectors, allowing better quality
compared to LSH for similar processing time when speed is the criterium.

* Add explanations on the FLANN's hierarchical KMeans for binary data.

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

Merge pull request #17722 from pemmanuelviel:pev--replace-asserts
* Clean: replace C style asserts by CV_Assert and CV_DbgAssert

* Try fixing warning on Windows compilation

* Another way trying to fix warnings on Win

* Fixing warnings with some compilers:
Some compilers warn on systematic exit preventing to execute the code that follows.
This is why assert(0) that exits only in debug was working, but not CV_Assert or CV_Error
that exit both in release and debug, even if with different behavior.
In addition, other compilers complain when return 0 is removed from getKey(),
even if before we have a statement leading to systematic exit.

* Disable "unreachable code" warnings for Win compilers so we can use proper CV_Error

482cacd420 Mix of 32 and 64bits vector types prevents vectorisation for distance computation.
Argument "a" is of type ElementType* that is either int* or float*, while b was double*.
Mixing types prevents the possibility to use SSE or AVX instructions.
On implementation without SIMD instructions, this doesn't show any impact on performance.
