[2/3]Bluetooth: add "Accept all files" option for incoming files via Bluetooth 

  This patch will let the OBEX server read "Accept all files" option
before it starts to check mime-type whitelist.
  If not enabled,the check process will go on as usual.
  If enabled,mime-type checking will be skipped.
