Document.adoptNode should not throw an exception for DocumentType argument

Document.adoptNode should not throw an exception
for DocumentType argument

According to spec, Document.adoptNode only throws exception on document.

spec: http://dom.spec.whatwg.org/#dom-document-adoptnode
  *)If node is a document, throw a "NotSupportedError" exception.

So this CL modified behavior as per specified.

TEST=LayoutTests/fast/dom/Document/adopt-node-with-doctype.html

In addition, with this CL, http://w3c-test.org/dom/nodes/Document-adoptNode.html
will be passed.

Behavior in other browsers:
  *)FF: pass
  *)IE: fail

LGTM, but tkent-san would want to confirm about the behavior change.

Thanks! Sure. :)
@tkent: Would you confirm about the behavior change?

lgtm.
I think the behavior change is safe because DocumentType nodes are rarely used.


CL description:
> Make Document.adoptNode more spec aligned

Please make it specific.  e.g. "Document.adoptNode should not throw an exception
for DocumentType argument"
