Add symbols for internals.

Source/WebCore: 

Fixed the bug by updating inner text value in setSuggestedValue.

Also added a suggestedValue and setSuggestedValue on window.internals for testing purposes.

Test: fast/forms/suggested-value.html

Source/WebKit/chromium: 

Chromium code incorrectly calls Node::isFocusable without updating layout, and was hitting assertions.
Fix the assertion failure (and a potential crash) by updating layout in WebCore::isFocusable.

(WebKit::WebNode::isFocusable):

Source/WebKit2: 

Add symbols for internals.

LayoutTests: 

Added a regression test to ensure HTMLInputElement updates its inner text value when the suggested value is set.

* fast/forms/suggested-value-expected.txt: Added.
* fast/forms/suggested-value.html: Added.
