Reviewed by Ryosuke Niwa.

Source/WebCore:

Code that needs to determine whether there are touch listeners
can instead call Document::touchEventHandlerCount(), added in r107832.
TOUCH_LISTENER didn't fit very well into the hasListenerType() model
anyway, as there's not a 1:1 correspondance between the enum value and
an event.

* dom/Document.cpp:
(WebCore::Document::addListenerTypeIfNeeded): Remove two bits of code:
the bookkeeping for TOUCH_LISTENER, and the notification into
ChromeClient (which is handled by calls to didAddTouchEventHandler in
all the places that call addListenerTypeIfNeeded).
(WebCore::Document::didRemoveTouchEventHandler): Remove bookkeeping for TOUCH_LISTENER.
* dom/Document.h:
* history/CachedFrame.cpp:
(WebCore::CachedFrameBase::restore): Call touchEventHandlerCount instead of hasListenerType.
* html/HTMLInputElement.cpp:
(WebCore::HTMLInputElement::updateType): ditto
* page/EventHandler.cpp:
(WebCore::EventHandler::handleTouchEvent): ditto
* page/Frame.cpp:
(WebCore::Frame::setDocument): ditto
* testing/Internals.cpp: Remove hasTouchEventListener method since its
data source no longer exists.
* testing/Internals.h: ditto
(Internals):
* testing/Internals.idl: ditto

Source/WebKit/chromium:

* src/WebPluginContainerImpl.cpp:
(WebKit::WebPluginContainerImpl::setIsAcceptingTouchEvents): Remove
bookkeeping for TOUCH_LISTENER.

LayoutTests:

Removed tests for hasTouchEventListener as they're redundant
with tests for touchEventHandlerCount.
