Subject: [PATCH] efm: fix bugs during renaming multiple files and copying file
 into same directory

Summary:
Since E_FM_OP_OVERWRITE_RESPONSE_NO was sent before file renaming, src had been changed as next file.
->send E_FM_OP_OVERWRITE_RESPONSE_NO after file renaming.

File became empty if I copy a file into same directory
--> first of all, prevent move, rename, symlink into same directory. in case of copy, attach " (copy)" postfix after file name automatically. (need to decide postfix policy)

fixes T739
