Merge pull request #22149 from seanm:sprintf 
Replaced sprintf with safer snprintf

* Straightforward replacement of sprintf with safer snprintf

* Trickier replacement of sprintf with safer snprintf

Some functions were changed to take another parameter: the size of the buffer, so that they can pass that size on to 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 ).
