Implement indirect method call: fun(obj, ...). * libinterp/octave-value/ov-classdef.h (class cdef_manager): New class. (cdef_method::cdef_method_rep::meta_subsref, cdef_method::cdef_method_rep::meta_is_postfix_index_handled): New methods. * libinterp/octave-value/ov-classdef.cc (all_packages, all_classes): Move static variables to class cdef_manager. (lookup_class (std::string, bool, bool)): Move implementation to method cdef_manager::do_find_class(). (lookup_package): Move implementation to method cdef_manager::do_find_package(). (make_class): Use cdef_manager::register_class. (make_package): Use cdef_manager::register_package and cdef_manager::find_package. (cdef_class::cdef_class_rep::meta_release): Use cdef_manager::unregister_class. (cdef_method::cdef_method_rep::meta_subsref): New method. (class cdef_manager): New class. * libinterp/interpfcn/symtab.cc (symbol_table::fcn_info::fcn_info_rep::load_class_constructor): Look for classdef constructor in normal m-files. Call find_user_function() and check whether the result is a classdef constructor. If it is, stash it as a constructor and restore the previous value of function_on_path. (symbol_table::fcn_info::fcn_info_rep::load_class_method): Look for method in classdef system, using cdef_manager::find_method_symbol().

## @deftypefn {Function File} {@var{b} =} loadobj (@var{a})
## Method of a class to manipulate an object after loading it from a file.
## The function @code{loadobj} is called when the object @var{a} is loaded
## using the @code{load} function.  An example of the use of @code{saveobj}
## might be to add fields to an object that don't make sense to be saved.
## For example:
##
## @example
## @group
## function b = loadobj (a)
##   b = a;
##   b.addmissingfield = addfield (b);
## endfunction
## @end group
## @end example
##
## @seealso{saveobj, class}
## @end deftypefn

function b = loadobj (a)
  error ('loadobj: not defined for class "%s"', class (a));
endfunction
