Multiple EDR connection in Tizen

Multiple EDR connection in Tizen

To support multiple EDR connection, the multicast data will be
added to an arraylist and as on when a device is discovered,
the data will be sent.  Once the discovery is finished, the data
will be removed from the arraylist.
Also the current implementation does discovery during initialization alone,
with this commit discovery will be done everytime when a multicast data
is sent.
