Patch by Mario Sanchez Prada <mario.prada@samsung.com> on 2013-09-20
Reviewed by Chris Fleizach.

Source/WebCore:

Stop exposing the value for the 'aria-help' attribute as an
AtkObject attribute, based in AccessibilityObject::helpText().

* accessibility/atk/WebKitAccessibleWrapperAtk.cpp:
(webkitAccessibleGetAttributes): Remove the mapping.

Source/WebKit/efl:

Removed accessibilityHelpText() helper method from
DumpRenderSupportEfl's API, since it's not longer needed.

* WebCoreSupport/DumpRenderTreeSupportEfl.cpp: Removed method.
* WebCoreSupport/DumpRenderTreeSupportEfl.h: Ditto.

Source/WebKit/gtk:

Removed accessibilityHelpText() helper method from
DumpRenderSupportGtk's API, since it's not longer needed.

* WebCoreSupport/DumpRenderTreeSupportGtk.cpp: Removed method.
* WebCoreSupport/DumpRenderTreeSupportGtk.h: Ditto.

Tools:

Remove the implementations for AccessibilityUIElement::helpText()
from DRT and WKTR for GTK and EFL, since they are based on the
AccessibilityObject::helpText() method and the 'aria-help'
attributes, which is wrong since they should not depend on that
but in ATK specific API (see also http://webkit.org/b/121684).

* DumpRenderTree/atk/AccessibilityUIElementAtk.cpp:
(AccessibilityUIElement::helpText): Added a new and empty
implementation, now that we are no longer using this in ATK.
* DumpRenderTree/efl/AccessibilityUIElementEfl.cpp: Removed file
as the only function provided here was helpText().
* DumpRenderTree/gtk/AccessibilityUIElementGtk.cpp: Ditto.
* DumpRenderTree/efl/CMakeLists.txt: AccessibilityUIElementEfl.cpp
removed from the list of sources to compile.
* GNUmakefile.am: Likewise, but for AccessibilityUIElementGtk.cpp.
* WebKitTestRunner/InjectedBundle/atk/AccessibilityUIElementAtk.cpp:
(WTR::AccessibilityUIElement::helpText): Replaced old implementation
based in DumpRenderTreeSupportGtk with an empty one.

LayoutTests:

Moved test based in helpText() into the Mac directory, and update
expectations for platforms as needed.

* platform/mac/accessibility/aria-help-expected.txt: Renamed from LayoutTests/accessibility/aria-help-expected.txt.
* platform/mac/accessibility/aria-help.html: Renamed from LayoutTests/accessibility/aria-help.html.
* platform/gtk-wk2/TestExpectations: Removed failure expectation
for aria-help, now moved to Mac, and for aria-describedby-on-input,
which is now moved to the generic TestExpectations file for GTK.
* platform/gtk/TestExpectations: Added aria-describedby-on-input,
linking it to the newly filed bug 121684.
* platform/gtk-wk2/TestExpectations: Removed failure expectation.
* platform/win/TestExpectations: Removed failure expectation.
* platform/wincairo/TestExpectations: Ditto.
