Reviewed by Tony Chang.

Source/WebCore:

The IndexedDB spec calls deleteDatabase() to fire a "blocked" event with the
IDBVersionChangeEvent interface which we were doing, but with an older interface - just
a "version" property. We were already firing an event on "versionchange" with the new
"oldVersion" and "newVersion" properties, but with an IDBUpgradeNeededEvent interface that
doesn't exist in the spec. This patch merges the event types to match the spec, including
that the newVersion property is null when deleting.

Test: storage/indexeddb/events.html
      storage/indexeddb/deletedatabase-*.html

* CMakeLists.txt: Remove references to deleted files.
* GNUmakefile.list.am: Ditto.
* Modules/indexeddb/IDBDatabase.cpp:
(WebCore::IDBDatabase::onVersionChange): Generate IDBVersionChangeEvent.
* Modules/indexeddb/IDBOpenDBRequest.cpp:
(WebCore::IDBOpenDBRequest::onBlocked): Ditto.
(WebCore::IDBOpenDBRequest::onUpgradeNeeded): Ditto.
* Modules/indexeddb/IDBUpgradeNeededEvent.cpp: Removed.
* Modules/indexeddb/IDBUpgradeNeededEvent.h: Removed.
* Modules/indexeddb/IDBUpgradeNeededEvent.idl: Removed.
* Modules/indexeddb/IDBVersionChangeEvent.cpp:
(WebCore::IDBVersionChangeEvent::create): Take IDBAny's as old/new versions
may be integers, strings (for legacy databases), or null (when deleting).
(WebCore::IDBVersionChangeEvent::IDBVersionChangeEvent):
* Modules/indexeddb/IDBVersionChangeEvent.h:
(IDBVersionChangeEvent): Remove version property.
(WebCore::IDBVersionChangeEvent::oldVersion): Added new property.
(WebCore::IDBVersionChangeEvent::newVersion): Added new property.
* Modules/indexeddb/IDBVersionChangeEvent.idl: Updated properties.
* WebCore.gypi: Remove references to deleted files.
* dom/EventNames.in: Ditto.

LayoutTests:

Updated expectations, and new test file. In most cases, just switch test from
looking at event.target.version and event.version to event.oldVersion and event.newVersion,
in some cases verifying the old properties as well as a sanity check.
