Merge pull request #19985 from fpetrogalli:disable_threads
* [build][option] Introduce `OPENCV_DISABLE_THREAD_SUPPORT` option.

The option forces the library to build without thread support.

* update handling of OPENCV_DISABLE_THREAD_SUPPORT

- reduce amount of #if conditions

* [to squash] cmake: apply mode vars in toolchains too

Merge pull request #18571 from vpisarev:add_lapack
Added clapack

* bring a small subset of Lapack, automatically converted to C, into OpenCV

* added missing lsame_ prototype

* * small fix in make_clapack script
* trying to fix remaining CI problems

* fixed character arrays' initializers

* get rid of F2C_STR_MAX

* * added back single-precision versions for QR, LU and Cholesky decompositions. It adds very little extra overhead.
* added stub version of sdesdd.
* uncommented calls to all the single-precision Lapack functions from opencv/core/src/hal_internal.cpp.

* fixed warning from Visual Studio + cleaned f2c runtime a bit

* * regenerated Lapack w/o forward declarations of intrinsic functions (such as sqrt(), r_cnjg() etc.)
* at once, trailing whitespaces are removed from the generated sources, just in case
* since there is no declarations of intrinsic functions anymore, we could turn some of them into inline functions

* trying to eliminate the crash on ARM

* fixed API and semantics of s_copy

* * CLapack has been tested successfully. It's now time to restore the standard LAPACK detection procedure
* removed some more trailing whitespaces

* * retained only the essential stuff in CLapack
* added checks to lapack calls to gracefully return "not implemented" instead of returning invalid results with "ok" status

* disabled warning when building lapack

* cmake: update LAPACK detection

Merge pull request #18716 from dmatveev:dm/upstream_onnx
* G-API: Introduce ONNX backend for Inference

- Basic operations are implemented (Infer, -ROI, -List, -List2);
- Implemented automatic preprocessing for ONNX models;
- Test suite is extended with `OPENCV_GAPI_ONNX_MODEL_PATH` env for test data
  (test data is an ONNX Model Zoo repo snapshot);
- Fixed kernel lookup logic in core G-API:
  - Lookup NN kernels not in the default package, but in the associated
    backend's aux package. Now two NN backends can work in the same graph.
- Added Infer SSD demo and a combined ONNX/IE demo;

* G-API/ONNX: Fix some of CMake issues

Merge pull request #16494 from StefanBruens:jpeg2000_openjpeg_port
Jpeg2000 OpenJPEG port

* OpenJPEG based JPEG2000 decoder implementation

Currently, the following input color spaces and depth conversions are
supported:

- 8 bit -> 8 bit
- 16 bit -> 16 bit (IMREAD_UNCHANGED, IMREAD_ANYDEPTH)

- RGB(a) -> BGR
- RGBA -> BGRA (IMREAD_UNCHANGED)
- Y(a) -> Y(a) (IMREAD_ANYCOLOR, IMREAD_GRAY, IMREAD_UNCHANGED))
- YCC -> Y (IMREAD_GRAY)

* Check for OpenJPEG availability

This enables OpenJPEG based JPEG2000 imread support by default, which
can be disabled by -DWITH_OPENJPEG=OFF. In case OpenJPEG is enabled
and found, any checks for Jasper are skipped.

* Implement precision downscaling for precision > 8 without IMREAD_UNCHANGED

With IMREAD_UNCHANGED, values are kept from the input image, without it
components are downscaled to CV_8U range.

* Enable Jpeg2K tests when OpenJPEG is available

* Add support for some more color conversions

Support IMREAD_GRAY when input color space is RGB or unspecified.
Support YUV input color space for BGR output.

* fix: problems with unmanaged memory

* fix: CMake warning - HAVE_OPENJPEG is undefined

Removed trailing whitespaces

* fix: CMake find_package OpenJPEG add minimal version

* Basic JPEG2K encoder

Images with depth CV_8U and CV_16U are supported, with 1 to 4 channels.

* feature: Improved code for OpenJPEG2000 encoder/decoder

 - Removed code duplication
 - Added error handlers
 - Extracted functions

* feature: Update conversion openjpeg array from/to Mat

* feature: Extend ChannelsIterator to fulfill RandomAccessIterator named requirements

 - Removed channels split in copyFromMatImpl. With ChannelsIterator no allocations are performed.
 - Split whole loop into 2 parts in copyToMat -> where std::copy and std::transforms are called.

* fix: Applied review comments.

 - Changed `nullptr` in CV_LOG* functions to `NULL`
 - Added `falls through` comment in decoder color space `switch`
 - Added warning about unsupported parameters for the encoder

* feature: Added decode from in-memory buffers.
