    ts: refactor OpenCV tests · 4a297a24
    Alexander Alekhin authored
    - 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
