* Using new smart_holder::reclaim_disowned in smart_holder_type_caster for unique_ptr. * Systematically renaming was_disowned to is_disowned (because disowning is now reversible: reclaim_disowned). * Systematically renaming virtual_overrider_self_life_support to trampoline_self_life_support (to reuse existing terminology instead of introducing new one). * Systematically renaming test_class_sh_with_alias to test_class_sh_trampoline_basic. * Adding a Trampolines and std::unique_ptr section to README_smart_holder.rst. * MSVC compatibility.
