__qualname__ on embedded/inner classes is wrong

[gabrielbocek]

Hi,

the qualname on embedded classes and enum returns just the embedded class/enum class. The outer class is not included. Here is a simple example:

BOOST_PYTHON_MODULE(TestModule)
{
    class TestClass
    {
    public:
        enum class EmbeddedEnum
        {
            eOff,
            eRepeat,
            eMirror
        };

        class EmbeddedClass
        {
            EmbeddedClass() = default;
        };

        TestClass() = default;
    };

    boost::python::class_<TestClass, boost::shared_ptr<TestClass>, boost::noncopyable> boostTestClass("TestClass", boost::python::no_init);
    boost::python::scope boostTestClassScope = boostTestClass;

    boost::python::enum_<TestClass::EmbeddedEnum> boostTestClassEmbeddedEnum("EmbeddedEnum");
    boostTestClassEmbeddedEnum.value("off", TestClass::EmbeddedEnum::eOff);
    boostTestClassEmbeddedEnum.value("repeat", TestClass::EmbeddedEnum::eRepeat);
    boostTestClassEmbeddedEnum.value("mirror", TestClass::EmbeddedEnum::eMirror);
    boostTestClassEmbeddedEnum.export_values();

    boost::python::class_<TestClass::EmbeddedClass, boost::shared_ptr<TestClass::EmbeddedClass>, boost::noncopyable> boostEmbeddedTestClass("EmbeddedClass", boost::python::no_init);
}

TestModule.TestClass.EmbeddedClass.__qualname__ returns just EmbeddedClass. Similarly the TestModule.TestClass.EmbeddedEnum returns EmbeddedEnum.

It should be TestClass.EmbeddedClass and TestClass.EmbeddedEnum respectively.
