Ticket #1044:
 - Added initial version of automatic re-registration after registration failure and automatic call disconnection after re-registration attempt fails.
 - Published auto re-registration setting to pjsua app.
 - Updated pjsip_regc_send() to retrieve the transport earlier (was only in tsx_callback()).
 - Fixed TCP and TLS transport to prevent transport deletion in transport disconnection callback.
 - Fixed wrong keep-alive settings used by TLS transport (was using TCP keep-alive settings).
