The final CL for plumbing DOM Storage.

Add webKitClient plumbing for getting/creating storage namespaces.  Add a chromium implementation for WebStorageArea and WebStorageNamespace which communicates via IPC with the dom_storage_dispatcher_host in the browser process.  Flesh out the StorageAreaProxy and StorageNamespaceProxy to use the aforementioned implementations.

The WebStorageArea implementation includes decently aggressive caching optimizations.  There's still a lot of work to do, though.

BUG=4360
TEST=none
