[CSS Regions] Remove the deprecated API Document.webkitGetFlowByName
https://bugs.webkit.org/show_bug.cgi?id=97657

Patch by Andrei Bucur <abucur@adobe.com> on 2012-10-01
Reviewed by Andreas Kling.

Source/WebCore:

The Document.getFlowByName() API has been deprecated in favor of the NamedFlowCollection.namedItem(DOMString).
Link to spec: http://www.w3.org/TR/css3-regions/#the-namedflow-interface

Tests: The old tests have been adapted to use the new API.

(WebCore):
* dom/Document.h:
(Document):
* dom/Document.idl:

LayoutTests:

To minimize the code change impact, I've created a new method in helper.js getFlowByName() that emulates the
behaviour of Document.webkitGetFlowByName(). All the occurrences of Document.webkitGetFlowByName in the tests/expected results
have been replaced with getFlowByName.
