Ticket #732:

 - Added new Symbian specific API in PJLIB, pj_symbianos_set_connection_status(), to let PJLIB knows the connection status.
 - Added connection status checks before Symbian socket operations.
 - Added loop limiter in Symbian busy_sleep() to avoid the possibility of infinite loop.
 - Added sample of connection monitor in Symbian sample application (ua.cpp).
