Reviewed by Tony Chang.

Source/WebCore:

Per spec, if the database connection is closed before the success event fires, the request
should have an error event of type AbortError fired at it.

Test: storage/indexeddb/intversion-close-in-upgradeneeded.html

* Modules/indexeddb/IDBDatabase.h:
(WebCore::IDBDatabase::isClosePending): Expose this state so an in-flight success can be morphed.
* Modules/indexeddb/IDBDatabaseBackendImpl.cpp:
(WebCore::IDBDatabaseBackendImpl::close): Fire the appropriate error at connections that are mid-opening.
* Modules/indexeddb/IDBOpenDBRequest.cpp:
(WebCore::IDBOpenDBRequest::onSuccess): If the connection was closed before the success is enqueued -
which can happen in multi-process ports with asynchronous messaging - convert the success to an error.

LayoutTests:

Update the test to match the spec behavior.
