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.

4a297a2443 ts: refactor OpenCV tests 
- removed tr1 usage (dropped in C++17)
- moved includes of vector/map/iostream/limits into ts.hpp
- require opencv_test + anonymous namespace (added compile check)
- fixed norm() usage (must be from cvtest::norm for checks) and other conflict functions
- added missing license headers

3. (SomeType*) someMatrix.data -> someMatrix.ptr<SomeType>()
4. someMatrix.data -> !someMatrix.empty() ( or !someMatrix.data -> someMatrix.empty() ) in logical expressions

7ea1bf3cf0 Fixed several problems found by PVS-Studio. 
This fixes all problems from the article "Checking OpenCV with PVS-Studio"
<http://www.viva64.com/en/b/0191/> that are not already fixed and are
not in 3rdparty or the legacy module.

The problems fixed are two instances of useless code and one instance
of unspecified behavior (right-shifting a negative number).

4f109d1292 Fixed a memory access error in CV_Remap_Test::generate_test_data. 
begin_x[1] is not the second component of the element, but the element
after the one pointed to begin_x. When begin_x points to the last
element, that line overwrites data past the end of the allocation, which,
during my tests, happened to contain the reference count for the matrix.
Hilarity ensues.
