Part of <http://webkit.org/b/31414> Implement new SPI for dealing with
user scripts/stylesheets and isolated worlds

Reviewed by Sam Weinig.

WebCore:

Covered by existing tests.

* WebCore.base.exp: Update exported symbols to match what now exists
and is needed by WebKit.

* bindings/js/ScheduledAction.cpp:
(WebCore::ScheduledAction::execute): Updated for function rename.

* bindings/js/ScriptController.cpp: Removed code that dealt with
worldIDs.
(WebCore::ScriptController::createWorld): Added. Returns a new world
suitable for use on the main thread.
(WebCore::ScriptController::executeScriptInWorld): Renamed from
executeScriptInIsolatedWorld, since this works just fine with a
"normal" world.

* bindings/js/ScriptController.h: Added createWorld, removed functions
that took worldIDs, renamed executeScriptInIsolatedWorld to
executeScriptInWorld.

* page/Frame.cpp:
(WebCore::Frame::injectUserScripts):
(WebCore::Frame::injectUserScriptsForWorld):
Updated for changes to UserScriptMap and ScriptController.

* page/Frame.h: Changed injectUserScriptsForWorld to take a
DOMWrapperWorld* instead of a worldID.

* page/PageGroup.cpp:
(WebCore::PageGroup::addUserScriptToWorld):
(WebCore::PageGroup::addUserStyleSheetToWorld):
(WebCore::PageGroup::removeUserScriptFromWorld):
(WebCore::PageGroup::removeUserStyleSheetFromWorld):
(WebCore::PageGroup::removeUserScriptsFromWorld):
(WebCore::PageGroup::removeUserStyleSheetsFromWorld):
* page/PageGroup.h:
Changed these functions to take a DOMWrapperWorld* instead of a
worldID. Also updated for changes to UserScript and UserStyleSheet.

* page/UserScript.h:
* page/UserStyleSheet.h: Changed not to hold a worldID, since it was
never used.

* page/UserScriptTypes.h:
* page/UserStyleSheetTypes.h: Changed UserScriptMap and
UserStyleSheetMap to use a RefPtr<DOMWrapperWorld> instead of a
worldID as their key type.

WebKit:

* WebKit.xcodeproj/project.pbxproj: Added WebScriptWorld to the project.

WebKit/mac:

WebScriptWorld is the new object that represents a world.  The only
place worldID is still used is in -[WebFrame
_stringByEvaluatingJavaScriptInIsolatedWorld:WithGlobalObject:FromString:],
but that will change soon.

* WebKit.exp: Export WebScriptWorld.

* WebView/WebFrame.mm:
(-[WebFrame _stringByEvaluatingJavaScriptInIsolatedWorld:WithGlobalObject:FromString:]):
Moved the bizarre world caching/creation logic that DRT depends on
here from the findWorld function in ScriptController.cpp. Updated to
use ScriptController::executeScriptInWorld instead of
ScriptController::executeScriptInIsolatedWorld.
(-[WebFrame _contextForWorld:]): Renamed from contextForWorldID:. Now
takes a WebScriptWorld.

* WebView/WebFramePrivate.h: Replaced contextForWorldID: with
_contextForWorld:.

* WebView/WebScriptWorld.h: Added.
* WebView/WebScriptWorld.mm: Added.
(-[WebScriptWorld initWithWorld:]): Store the passed-in world in our
_private member.
(-[WebScriptWorld init]): Create a new DOMWrapperWorld and pass it to
-initWithWorld:.
(-[WebScriptWorld dealloc]): Release _private.
(+[WebScriptWorld standardWorld]): Returns a shared instance that
represents WebCore's mainThreadNormalWorld().
(+[WebScriptWorld world]): Returns a new instance.
(core): Returns the DOMWrapperWorld for this WebScriptWorld.

* WebView/WebScriptWorldInternal.h: Added.

* WebView/WebView.mm:
(+[WebView _addUserScriptToGroup:world:source:url:whitelist:blacklist:injectionTime:]):
(+[WebView _addUserStyleSheetToGroup:world:source:url:whitelist:blacklist:]):
(+[WebView _removeUserScriptFromGroup:world:url:]):
(+[WebView _removeUserStyleSheetFromGroup:world:url:]):
(+[WebView _removeUserScriptsFromGroup:world:]):
(+[WebView _removeUserStyleSheetsFromGroup:world:]):
* WebView/WebViewPrivate.h:
Changed these functions to take a WebScriptWorld instead of a worldID.

WebKit/win:

WebScriptWorld is the new object that represents a world.  The only
place worldID is still used is in
IWebFramePrivate::stringByEvaluatingJavaScriptInIsolatedWorld, but
that will change soon.

* ForEachCoClass.h: Added WebScriptWorld.

* Interfaces/IWebFramePrivate.idl: Replaced contextForWorldID with
contextForWorld.

* Interfaces/IWebScriptWorld.idl: Added.

* Interfaces/IWebViewPrivate.idl: Changed the user script/stylesheet
functions to take an IWebScriptWorld instead of a worldID.

* Interfaces/WebKit.idl: Added WebScriptWorld.

* WebFrame.cpp:
(WebFrame::contextForWorld): Renamed from contextForWorldID. Now takes
an IWebScriptWorld.
(WebFrame::stringByEvaluatingJavaScriptInIsolatedWorld): Moved the
bizarre world caching/creation logic that DRT depends on here from the
findWorld function in ScriptController.cpp. Updated to use
ScriptController::executeScriptInWorld instead of
ScriptController::executeScriptInIsolatedWorld.

* WebFrame.h: Replaced contextForWorldID with contextForWorld.

* WebScriptWorld.cpp: Added.
(WebScriptWorld::WebScriptWorld):
(WebScriptWorld::~WebScriptWorld):
(WebScriptWorld::createInstance):
(WebScriptWorld::AddRef):
(WebScriptWorld::Release):
(WebScriptWorld::QueryInterface):
Standard COM class implementations.

(WebScriptWorld::standardWorld): Returns a shared instance that represents
WebCore's mainThreadNormalWorld().

* WebScriptWorld.h: Added.
(WebScriptWorld::world): Simple getter.

* WebKit.vcproj/Interfaces.vcproj: Added IWebScriptWorld.idl.

* WebKit.vcproj/WebKit.vcproj: Added WebScriptWorld.

* WebKitClassFactory.cpp: Added WebScriptWorld.

* WebView.cpp:
(WebView::addUserScriptToGroup):
(WebView::addUserStyleSheetToGroup):
(WebView::removeUserScriptFromGroup):
(WebView::removeUserStyleSheetFromGroup):
(WebView::removeUserScriptsFromGroup):
(WebView::removeUserStyleSheetsFromGroup):
* WebView.h:
Changed these functions to take an IWebScriptWorld instead of a worldID.

WebKitTools:

* DumpRenderTree/mac/LayoutTestControllerMac.mm:
(LayoutTestController::addUserScript):
(LayoutTestController::addUserStyleSheet):
* DumpRenderTree/win/LayoutTestControllerWin.cpp:
(LayoutTestController::addUserScript):
