[PATCH obexd 3/7 v3] client: Add filters to PhonebookAccess.List and PhonebookAccess.Search

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This avoid D-Bus round trips and is more aligned with what has been
proposed for MessageAccess interface.
