Replaced sprintf with safer snprintf

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.

c8268e65fd Fix potential NaN in cv::norm. 
There can be an int overflow.
cv::norm( InputArray _src, int normType, InputArray _mask ) is fine,
not cv::norm( InputArray _src1, InputArray _src2, int normType, InputArray _mask ).

Merge pull request #20011 from Developer-Ecosystem-Engineering:3.4 
Improve performance on Arm64

* Improve performance on Apple silicon

This patch will
- Enable dot product intrinsics for macOS arm64 builds
- Enable for macOS arm64 builds
- Improve HAL primitives
  - reduction (sum, min, max, sad)
  - signmask
  - mul_expand
  - check_any / check_all

Results on a M1 Macbook Pro

* Updates to #20011 based on feedback

  - Removes Apple Silicon specific workarounds
  - Makes #ifdef sections smaller for v_mul_expand cases
  - Moves dot product optimization to compiler optimization check
  - Adds 4x4 matrix transpose optimization

* Remove dotprod and fix v_transpose

Based on the latest, we've removed dotprod entirely and will revisit in a future PR.

Added explicit cats with v_transpose4x4()

This should resolve all opens with this PR

* Remove commented out lines

Remove two extraneous comments

Merge pull request #19967 from HattrickGenerator:master 
* Adding functions rbegin() and rend() functions to matrix class.
This is important to be more standard compliant with C++ and an ever increasing number of people using standard algorithms for better code readability- and maintainability.

The functions are copy pated from their counterparts (even though they should probably call the counterparts but this gave me some troube).
They return iterators using std::reverse_iterators

Follow up of an open feature request:
https://github.com/opencv/opencv/issues/4641

* Fix rbegin() and rend() and provide tests for them

* Removing unnecessary whitespaces

* Adding rbegin and rend to Mat_ class with the right parameters so we don't need to repeat the template argument.
An instantiating cv::Mat_<int> for example can call it's rbegin() function and doesn't need rbegin<int>() with this convience addition.

Follows what is done for forward iterators

* static cast the vector size (return size_t) to an int (that is required for opencv mat constructor)
