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
