Revert 116712 - Source/WebCore: [chromium] DomStorage events handling needs TLC (2)
https://bugs.webkit.org/show_bug.cgi?id=85221
Alter the StorageArea virtual interface such that the mutators no longer
return old values. This is to allow implementations of the interface to operate
more asynchronously.

Reviewed by Adam Barth.

No new tests. Existing tests cover this.

* storage/StorageArea.h: Alter the interface so the mutators no longer return previous values
* storage/StorageAreaImpl.cpp:
(WebCore::StorageAreaImpl::disabledByPrivateBrowsingInFrame):  removed an unneeded PLATFORM(CHROMIUM) guard
(WebCore::StorageAreaImpl::setItem): no longer return the old value
(WebCore::StorageAreaImpl::removeItem): no longer return the old value
(WebCore::StorageAreaImpl::clear): no longer return whether something was cleared
* storage/StorageAreaImpl.h: match StorageArea's virtual interface

Alter the WebStorageArea virtual interface such that the mutators no longer
return old values. This is to allow implementations of the interface to operate
more asynchronously.

Also clean up from the last patch, remove support for the DEPRECATED event
dispatching API.
