Subject: [PATCH BlueZ v3] obexd: support to reply folder name to store file

The obex agent usually reply the filename by getting the default filename
from the filename property of the transfer object which is not convenient.
The patch helps that the obex agent can reply folder name or new filename
or null which will use the default filename if new_name is NULL and the
default folder if the new_folder is NULL in opp_chkput().
