Implement full object construction and superclass references. * libinterp/octave-value/ov-classdef.h (cdef_object_rep::subsref): Add class context argument. (cdef_object_rep::ctor_list): New class member. (cdef_object_rep::mark_for_construction, cdef_object_rep::is_constructed_for, cdef_object_rep::is_partially_constructed_for, cdef_object_rep::mark_as_constructed, cdef_object_rep::is_constructed, cdef_object::mark_for_construction, cdef_object::is_constructed_for, cdef_object::is_partially_constructed_for, cdef_object::mark_as_constructed, cdef_object:is_constructed): New methods to manipulate the new ctor_list class member. (cdef_object_rep::cdef_object_rep (const cdef_object_rep&)): New copy constructor. (cdef_class::cdef_class_rep (std::string, std::list<cdef_class>)): New utility constructor. (cdef_class (std::string, std::list<cdef_class>)): Likewise. (cdef_class::cdef_class_rep::implicit_ctor_list): New class member. (cdef_method::cdef_method_rep::is_constructor, cdef_method::is_construcror): New methods. (cdef_method::get_function): Likewise. (cdef_package::cdef_package_rep::subsref): Remove method. (octave_classdef::get_object_ref): New method. (to_cdef_ref): New function. * libinterp/octave-value/ov-classdef.cc (is_superclass): Add max_depth argument. (is_direct_superclass): New utility function. (get_class_context): Add bool and std::string return values, as new reference arguments. Add overload without any arguments. (check_access): Check for valid class context when required. (make_class): Remove super_name_list argument. Do not set SuperClasses explicitly, use new cdef_class constructor instead. (octave_classdef::subsref): Change skip variable to size_t (avoids compilation warning). Call cdef_object::subsref with additional class context argument. (class octave_classdef_superclass_ref): New utility class. (F__superclass_reference__): Use it. (cdef_object_rep::subsref): Add class context argument. (cdef_object_rep::mark_for_construction): New method. (handle_cdef_object::~handle_cdef_object, value_cdef_object::~value_cdef_object, cdef_class::cdef_class_rep::subsref_meta, cdef_class::make_meta_class): Use gnulib::printf explicitly. (cdef_class::cdef_class_rep (std::string, std::list<cdef_class>)): New constructor. (class ctor_analyzer): New utility class. (cdef_class::cdef_class_rep::install_method): Use it to analyze constructors and detect explicit superclass constructor calls. (cdef_class::cdef_class_rep::initialize_object): Call cdef_object::mark_for_construction. (cdef_class::cdef_class_rep::run_constructor): Run all implicit superclass constructors first. (cdef_class::cdef_class_rep::construct): Call cdef_object::mark_as_constructed. (cdef_class::make_meta_class): Remove snamelist variable. (cdef_property::cdef_property_rep::get_value, cdef_property::cdef_property_rep::set_value): Check if object is partially constructed for the property-defining class. (cdef_method::cdef_method_rep::is_constructor): New method. (cdef_package::cdef_package_rep::subsref): Delete method.
