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).
