Alexander Alekhin d573472a86 Merge remote-tracking branch 'upstream/3.4' into merge-3.4 2022-01-31 12:53:45 +00:00
Vadim Levin d88730685e fix: submodules creation and registration 
- Add special case handling when submodule has the same name as parent
- `PyDict_SetItemString` doesn't steal reference, so reference count
  should be explicitly decremented to transfer object life-time
  ownership
- Add sanity checks for module registration input
- Add Python 2 and Python 3 reference counting handling

Yuriy Chernyshov d1b533d399 Disable -Wreturn-type-c-linkage under clang-cl 
clang-cl defines both __clang__ and _MSC_VER, yet uses `#pragma GCC` to disable certain diagnostics.

At the time `-Wreturn-type-c-linkage` was reported by clang-cl.
This PR fixes this behavior by reordering defines.

Vincent Rabaud 6b4ea68bc7 Solve Rect overflow issues. 
Fow now, it is possible to define valid rectangle for which some
functions overflow (e.g. br(), ares() ...).
This patch fixes the intersection operator so that it works with
any rectangle.

Vincent Rabaud ffd010767f Only use fma functions when CV_FMA3 is set. 
In practice, processors offering AVX2/AVX512 also FMA, that is why it got unnoticed.
