e3da18121f Enable a GMainLoop when capturing using GStreamer 
A running GMainLoop processes many events on the GLib/GStreamer
world. While some things may work without it, many others wont.
Examples of these are signals, timers and many other source
events. The problem becomes more concerning by the fact that
some GStreamer elements rely on signals to work.

This commit allows the user to specify an OpenCV option to
start a main loop, if needed. Since the loop blocks, this is
done in a separate thread.

Merge pull request #18261 from OrestChura:oc/fluid_convert_mask 
[G-API]: Fluid: add mask, extend convertTo for CV_16S

* Add Fluid `mask` kernel + Acc. and Perf. tests
 - simple cycle implementation with restrictions on mask type and input/output type like in OCV/GPU kernels (mask - CV_8UC1 only, input/output - CV_8UC1, CV_16UC1, CV_16SC1)

* Added convertions from/to 16S

* `convertTo()` perf tests refactoring
 - add testing of `alpha` and `beta` parameters
 - fixed unreliable comparison
 - added instances to OCV, Fluid and GPU tests according to the changes

* Addressing comments
 - fixed multiple-channel mistake - prohibited multiple-channeling

* Reduced perf tests

Merge pull request #18257 from OrestChura:oc/fluid_operator_bitwise_and_scalar 
[G-API]: Add Fluid bitwise operations implementation for (GMat, GScalar)

* Added Fluid `bitwise` with `Scalar` + acc.tests
 - simple loop implementation for Fluid used (no `hal`);
   - `Scalar` is casted to `int` in the beginning
 - tests just modified to work with `Scalar`
 - expected output in operators' tests fixed (operators can't change Mat's depth)
 - `float` `Scalar` `RNG` added, `RNG` reworked (`time` is used now), initialization of test fixtures reworked
   - if input or output is `float` Scalar is initialized by `float`
 - some problems with Fluid/OCV floating-point comparison difference stashed by `AbsSimilarPoints()` usage, FIXME added
 - divide-by-zero is now fixed differently and everywhere

* - Added perf_tests for bitwise_Scalar operations
 - due to errors of Fluid floating-point comparison operations, added support of different validation in Cmp perf_tests; added FIXME

 - reworked integral initialization of Scalar

* Addressing comments
 - NULL -> nullptr
 - Scalar convertion moved to the function
 - avoid -> avoiding

* Addressing comments

* CV_assert -> GAPI_assert

* Addressed DM comments
 - refactored convertScalarForBitwise()
 - removed unnecessary braces for switch

* Changed the operators tests
 - switch via `enum` implemented
 - infrastructure for that refactored

* refactor: removed obsolete FFMPEG version support

 - Oldest available version via official FFMPEG repository mirror has tag v.0.5
 LIBAVFORMAT version for this tag is 52.31.0

* refactor: prefer std::min function to MIN macro

* refactor: use appropriate macro instead of manual version calculation

* refactor: remove macros for versions prior 0.5.15 release

* refactor: remove libavcodec macros for versions < 54.35.1 (default to Ubuntu 14.04)

* refactor: remove libavformat macro for versions < 54.20.4 (default ubuntu 14.04)

* refactor: remove libavutil macro for versions < 52.3.0 (default ubuntu 14.04)

* refactor: remove missed macros for libavcodec and libavformat

* refactor: remove unused _opencv_ffmpeg_free function

* build: add FFMPEG libraries versions checks

 - Add verbose message about what FFMPEG libraries are missing.
 - Add minimal versions check set to libav 9.20 release (default ubuntu 14.04) and FFMPEG 1.1.16 release.
   If the check is failed CMake produces user-friendly message instead of build error.

* fix: libavcodec version guard for AVDISCARD_NONINTRA

* fix: libav check of libavcodec version guard for AVDISCARD_NONINTRA

* fix: version check for AV_CODEC_FLAG_GLOBAL_HEADER

da555a2c9b Optimize opencv dft by vectorizing radix2 and radix3. 
This is useful for non power-of-two sizes when WITH_IPP is not an option.

This shows consistent improvement over openCV benchmarks, and we measure
even larger improvements on our internal workloads.

For example, for 320x480, `32FC*`, we can see a ~5% improvement}, as
`320=2^6*5` and `480=2^5*3*5`, so the improved radix3 version is used.
`64FC*` is flat as expected, as we do not specialize the functors for `double`
in this change.

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 #17885 from alalek:dnn_ocl_slice_update 
DNN: OpenCL/slice update

* dnn(ocl/slice): make slice kernel VTune friendly

- more unique names
- inline code of copy functions

* dnn(ocl/slice): prefer to spawn more work groups

- even in case with 1D copy
- perf improvement up to 2x of kernel time (due to changed configuration 128x1x1 => 128x32x1)

* dnn(ocl/slice): cache kernel exec info

Merge pull request #17858 from vpisarev:dnn_depthwise_conv 
* added depth-wise convolution; gives ~20-30% performance improvement in MobileSSD networks

* hopefully, eliminated compile warnings, errors, as well as failure in one test

* * fixed a few typos
* decreased buffer size in some cases
* added more optimal im2row branch in the case of 1x1 convolutions
* tuned fastConv to reduce the number of passes over arrays
