Reviewed by Gustavo Noronha Silva.

Source/WebCore:

Some of the DOM methods can create a concrete instance of another
object, but return a base class. GObject bindings provide custom
kit implementations for Node, Element, Event and EvenTarget, so
any concrete HTMLElement wrapped as an HTMLElement ends up
wrapping the right WebCore object but in the wrong GObject type.
This affects not only HTMLElements, but any polymorphic object
wrapped using a base class.
This patch changes the way objects are created, so that all
classes have their own kit implementation, but for polymorphic
objects the kit implementation of the base class is always
used. The kit method of polymorphic base classes use a generic
wrap method instead of the wrapFoo method like all other
classes. In the static code we provide the implementation of the
generic wrap method for every polimorphic base class, falling back
to their wrapFoo method if the concrete object can't be used to
wrap the object.
Both WebKitDOMBinding and WebKitHTMLElementWrapperFactory now provide
implementations of wrap and have been renamed to WebKitDOMPrivate
and WebKitDOMHTMLPrivate.

* bindings/gobject/GNUmakefile.am:
* bindings/gobject/WebKitDOMBinding.cpp: Removed.
* bindings/gobject/WebKitDOMEventTarget.cpp:
(WebKit::kit): Moved kit implementation from WebKitDOMBinding for
consistency with all other objects that have their own kit.
(WebKit::core): Updated to match the core implementation fo all
other objects.
* bindings/gobject/WebKitDOMEventTargetPrivate.h:
(WebCore):
(WebKit):
* bindings/gobject/WebKitDOMHTMLPrivate.cpp: Added.
(WebKit): Use preprocessor macros to define and set the wrap
functions of all HTML elements, removing a lot of boilerplate code
and making it easier to add new wrap functions in the future.
(WebKit::wrap):
* bindings/gobject/WebKitDOMHTMLPrivate.h: Renamed from Source/WebCore/bindings/gobject/WebKitHTMLElementWrapperFactory.h.
(WebCore):
(WebKit):
* bindings/gobject/WebKitDOMObject.cpp:
* bindings/gobject/WebKitDOMPrivate.cpp: Added.
(WebKit):
(WebKit::wrap):
* bindings/gobject/WebKitDOMPrivate.h: Renamed from Source/WebCore/bindings/gobject/WebKitDOMBinding.h.
(WebCore):
(WebKit):
* bindings/gobject/WebKitHTMLElementWrapperFactory.cpp: Removed.
* bindings/scripts/CodeGeneratorGObject.pm:
(IsBaseType): Helper function to check if a type is a base class.
(GetBaseClass): Helper function to get the base class for a given
parent type.
(GenerateFunction): Remove special case for EventTarget since the
kit prototype of EventTarget is in its private header like all
other objects.
(GenerateCFile): Add a kit implementation for all objects.
(IsPolymorphic): Helper function to check if the given type is the
base class of a polymorphic object.
(Generate): Include the private header of the base class for
polymorphic objects.
(WriteData): Remove the special case for WebKitDOMNode since now
all objects has a kit method.

been renamed and it was not actually needed.
