<h3>Log Message</h3>
<pre>Add document.defineCustomElement
https://bugs.webkit.org/show_bug.cgi?id=153092
Reviewed by Chris Dumez.
Source/WebCore:
Added document.defineCustomElement and added a constructor to HTMLElement which can be called
as "super" in a subclass of HTMLElement. This is a prototype of new custom elements API and
willfully violates the current specification at http://w3c.github.io/webcomponents/spec/custom/
Each author defined class can define multiple elements using distinct tag names. In such cases,
the super call must specify the tag name. e.g.
class SomeCustomElement extends HTMLElement { constructor(name) { super(name); } }
document.defineCustomElement('some-custom-element', SomeCustomElement);
document.defineCustomElement('other-custom-element', SomeCustomElement);
new SomeCustomElement('some-custom-element');
When a class is associated with exactly one tag name, the argument can be omitted. e.g.
class AnotherCustomElement extends HTMLElement {}
document.defineCustomElement('another-custom-element', AnotherCustomElement);
new AnotherCustomElement();
We allow only subclassing of HTMLElement and only in (X)HTML namespace.

* CMakeLists.txt:
* WebCore.xcodeproj/project.pbxproj:
* bindings/js/JSCustomElementInterface.cpp: Added. Abstracts an author-defined class associated
with a custom element. It's a Active DOM object and lives until the associated document dies.
(WebCore::JSCustomElementInterface::JSCustomElementInterface):
(WebCore::JSCustomElementInterface::~JSCustomElementInterface):
* bindings/js/JSCustomElementInterface.h: Added.

(WebCore::JSDocument::defineCustomElement): Added. Define a custom element by associating a tag
name with an author defined JS class after validating arguments.
* bindings/js/JSHTMLElementCustom.cpp:
(WebCore::constructJSHTMLElement): Added. Look up the tag name based on new.target if one is not
specified. If a tag name is specified, check that new.target is associated with the tag name.
* dom/CustomElementDefinitions.cpp: Added.
(WebCore::CustomElementDefinitions::checkName): Added. Restricts tag names similarly to
http://w3c.github.io/webcomponents/spec/custom/#dfn-custom-element-type
(WebCore::CustomElementDefinitions::defineElement): Added. Associates a JS class with a tag name.
(WebCore::CustomElementDefinitions::findInterface): Added. Finds a JS class by a tag name.
(WebCore::CustomElementDefinitions::findName): Added. Finds a tag name by a JS class.

+ Add document.defineCustomElement
+ https://bugs.webkit.org/show_bug.cgi?id=153092
+
+ Reviewed by Chris Dumez.
+
+ Added document.defineCustomElement and added a constructor to HTMLElement which can be called
+ as "super" in a subclass of HTMLElement. This is a prototype of new custom elements API and
+ willfully violates the current specification at http://w3c.github.io/webcomponents/spec/custom/
+
+ Each author defined class can define multiple elements using distinct tag names. In such cases,
+ the super call must specify the tag name. e.g.
+
+ class SomeCustomElement extends HTMLElement { constructor(name) { super(name); } }
+ document.defineCustomElement('some-custom-element', SomeCustomElement);
+ document.defineCustomElement('other-custom-element', SomeCustomElement);
+ new SomeCustomElement('some-custom-element');
+
+ When a class is associated with exactly one tag name, the argument can be omitted. e.g.
+
+ class AnotherCustomElement extends HTMLElement {}
+ document.defineCustomElement('another-custom-element', AnotherCustomElement);
+ new AnotherCustomElement();
+
+ We allow only subclassing of HTMLElement and only in (X)HTML namespace.
+
+ Tests: fast/custom-elements/Document-defineCustomElement.html
+ fast/custom-elements/HTMLElement-constructor.html
+
+ * CMakeLists.txt:
+ * WebCore.xcodeproj/project.pbxproj:
+
+ * bindings/js/JSCustomElementInterface.cpp: Added. Abstracts an author-defined class associated
+ with a custom element. It's a Active DOM object and lives until the associated document dies.
+ (WebCore::JSCustomElementInterface::JSCustomElementInterface):
+ (WebCore::JSCustomElementInterface::~JSCustomElementInterface):
+ * bindings/js/JSCustomElementInterface.h: Added.
+ (WebCore::JSCustomElementInterface::create):
+ (WebCore::JSCustomElementInterface::scriptExecutionContext):
+ (WebCore::JSCustomElementInterface::constructor):
+
+ * bindings/js/JSDocumentCustom.cpp:
+ (WebCore::JSDocument::defineCustomElement): Added. Define a custom element by associating a tag
+ name with an author defined JS class after validating arguments.
+
+ * bindings/js/JSHTMLElementCustom.cpp:
+ (WebCore::constructJSHTMLElement): Added. Look up the tag name based on new.target if one is not
+ specified. If a tag name is specified, check that new.target is associated with the tag name.
+
+ * dom/CustomElementDefinitions.cpp: Added.
+ (WebCore::CustomElementDefinitions::checkName): Added. Restricts tag names similarly to
+ http://w3c.github.io/webcomponents/spec/custom/#dfn-custom-element-type
+ (WebCore::CustomElementDefinitions::defineElement): Added. Associates a JS class with a tag name.
+ (WebCore::CustomElementDefinitions::findInterface): Added. Finds a JS class by a tag name.
+ (WebCore::CustomElementDefinitions::findName): Added. Finds a tag name by a JS class.
+ * dom/CustomElementDefinitions.h: Added.
+ (WebCore::CustomElementDefinitions::CustomElementInfo): Added.

+ * dom/Document.cpp:
+ (WebCore::Document::ensureCustomElementDefinitions): Added.
+ * dom/Document.h:
