Fyi2, we're changing the MountPointProvider naming to FileSystemBackends
everywhere. (Many pending conflicting changes due to Jul 4!)

https://codereview.chromium.org/18344013/

After the rename patch is submitted maybe we can simply name this class
'SyncFileSystemBackends'?

Thanks! Rebased and renamed.
