(WebCore::ColorInputType::didCleanup): Called after cleanup is complete.
(WebCore::ColorInputType::cleanupColorChooser): Renamed from cleanupColorChooserIfCurrentClient.
* html/ColorInputType.h:
* html/HTMLInputElement.cpp:
(WebCore::HTMLInputElement::selectColorInColorChooser):
* html/HTMLInputElement.h:
* loader/EmptyClients.h:
(WebCore::EmptyChromeClient::cleanupColorChooser): Added colorChooser argument because there are many WebCore::ColorChoosers now.
(WebCore::EmptyChromeClient::setSelectedColorInColorChooser): Ditto.

(WebCore::ColorChooser::ColorChooser): ColorChooser is RefCounted.
(WebCore::ColorChooser::create): Creates a ColorChooser that is connected to the given ColorChooserClient.
(WebCore::ColorChooser::~ColorChooser):
(WebCore::ColorChooser::didChooseColor): Called from WebKit side when user chose a color. Calls ColorChooserClient::didChooseColor
(WebCore::ColorChooser::didCleanup): Called from WebKit side when user color chooser was cleaned up. Calls ColorChooserClient::didCleanup
* platform/ColorChooser.h:
(WebCore::ColorChooserClient::chooser): Returns the current ColorChooser.
(WebCore::ColorChooser::disconnectClient): Disconnects the ColorChooserClient.
* testing/Internals.cpp:
(WebCore::Internals::selectColorInColorChooser): Added element argument. This calls didChooseColor on the ColorChooser of that element.

LayoutTests:

* fast/forms/color/input-color-onchange-event.html: Changed to match the changes to window.internals object
