parent class and interfaces (because we don't want to see the
warnings about certain GtkWidget methods in every single library
that defines a widget, etc). Instead, use the new
ValidateForSubclass() method.
(ValidateForSubclass): only validate the signals
* generator/InterfaceGen.cs (ValidateForSubclass): for interfaces
we need to validate the methods too.
* generator/ObjectGen.cs (Generate): Check for interface method
collisions against the class's own methods too, not just its other
interfaces. Also, it's only a collision if the methods' signatures
have the same types.
* generator/Signal.cs (GenDefaultHandlerDelegate): Use
"{0}_managed" rather than "obj" for the internal variable name, to
avoid compile problems with signals that have a parameter named
"obj".
* generator/SymbolTable.cs (MangleName): mangle "internal" to
"_internal".
