* Initial version of virtual_overrider_self_life_support (enables safely passing unique_ptr to C++). * Clang 3.6, 3.7 compatibility. * Adding missing default constructor. * Restoring test for exception for the case that virtual_overrider_self_life_support is not used. * Fixing oversight: Adding missing holder().ensure_was_not_disowned(). * Adding unit tests for new `struct smart_holder` member functions. * Moving virtual_overrider_self_life_support to separate include file, with iwyu cleanup.
