Abstract the meta-protocol layer to use it for other meta objects.
* libinterp/octave-value/ov-classdef.h (class cdef_meta_object_rep,
class cdef_meta_object): New classes.
(cdef_object_rep::is_class, cdef_object_rep::is_method,
cdef_object_rep::is_property, cdef_object_rep::is_package): Moved to
cdef_meta_object_rep.
(cdef_object::is_class, cdef_object::is_method, cdef_object::is_property,
cdef_object::is_package): Moved to cdef_meta_object.
(cdef_object_rep::is_handle_object, cdef_object_rep::is_value_object,
cdef_object_rep::is_meta_object): New virtual methods.
(cdef_object::is_handle_object, cdef_object::is_value_object,
cdef_object::is_meta_object): New methods.
(handle_cdef_object::is_handle_object): New method.
(value_cdef_object::is_value_object): Likewise.
(class cdef_class, class cdef_property, class_cdef_method,
class cdef_package): Inherit from cdef_meta_object.
(class cdef_class::cdef_class_rep, class cdef_property::cdef_property_rep,
class cdef_method::cdef_method_rep, class cdef_package::cdef_package_rep):
Inherit from cdef_meta_object_rep.
(cdef_class::cdef_class_rep::meta_subsref): Renamed from subsref_meta.
(cdef_class::cdef_class_rep::meta_release,
cdef_class::cdef_class_rep::meta_is_postfix_index_handled): New method, moved
from octave_classdef_proxy.
(cdef_class::operator=(const cdef_object&)): Remove method.
(cdef_class::subsref_meta): Remove method, replaced by
cdef_meta_object::meta_subsref.
(cdef_method::cdef_method(const cdef_method&)): Fix signature of copy
constructor, was using "const cdef_property&".
(cdef_package::cdef_package(const cdef_package&)): Add copy constructor.
* libinterp/octave-value/ov-classdef.cc (class octave_classdef_meta): Renamed
from octave_classdef_proxy.
(octave_classdef_meta::meta_subsref): Method renamed from subsref_meta.
(octave_classdef_meta::meta_subsref, octave_classdef_meta::octave_classdef_meta,
octave_classdef_meta::is_postfix_index_handled): Forward calls to
cdef_meta_object.
(cdef_class::cdef_class_rep::meta_subsref): Renamed from subsref_meta.
(cdef_class::cdef_class_rep::meta_release): New method.
(cdef_class::get_method_function): Use renamed class octave_classdef_meta.
(cdef_class::cdef_class_rep::cdef_class_rep): Inherit from cdef_meta_object_rep.
