new methods to allow arbitrary setup and teardown code around the managed call. When passing a type with "complicated" marshalling requirements as a ref or out param, first assign the value to a temporary variable (in Setup), then pass the temp as the ref or out param (in ToString), and then assign the new value back to the original argument (in Finish). * generator/Signal.cs: * generator/SignalHandler.cs: Update to generate correct glue for signals with "ref" or "out" params. (#70566) * generator/VirtualMethod.cs: Update for ManagedCallString change * generator/IGeneratable.cs: add comments explaining what each member does * gtk/Gtk.metadata: mark Editable.InsertText's "position" arg * pass-by-ref * sample/Size.cs: connect to the SizeRequested event and override it, to test/demo the changes svn path=/trunk/gtk-sharp/; revision=37854
