v2.7.0 release

Fixing another `git rebase master` accident.

Merge branch 'test_unique_ptr_member' into pr2672_use_smart_holder_as…

…_default

Adding source code comments in response to review.

Manipulating failing ConstructorStats test to pass, to be able to run…

… all tests with ASAN.

This version of the code is ASAN clean with unique_ptr or smart_holder as the default.

This change needs to be reverted after adopting the existing move-only-if-refcount-is-1
logic used by type_caster_base.

Demonstrating that py::cast<std::unique_ptr<Foo>>(foo_py); works with…

… py::classh (it does not build with class_).
