Exceptions caught by value incur needless cost in C++, most of them can
be caught by const-reference, especially as nearly none are actually
used. This could allow compiler generate a slightly more efficient code.
- 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
This and several following commits contain the "boring" changes required
to support the new Ptr. These are changes like:
* new T -> makePtr<T> or .reset(new T) or Ptr<T>(new T)
(depending on the situation)
* p.empty() -> !p
* delete_obj -> DefaultDeleter::operator()
and similar changes that are numerous, but primitive.
