Changed the EStorageSet API to have a single `xfer()' method instead

of separate copy/move (as in the IDL).  Actually implement the
`xfer()' operation for the case when source and destination are in the
same storage.  Fix the `EStorageSet' API by having a special
`EStorageSetResultCallback' callback type for it (instead of using
`EStorageResultCallback', which would never work).

Also, removed some unused variables in `e-storage-set-view.c'.
