Message:

Fixed #1902:

• Crash when endpoint has multiple worker threads and SIP TCP transport is disconnected during incoming call handling.
• Deprecated pjsip_dlg_create_uas(), replaced by pjsip_dlg_create_uas_and_inc_lock().
• Serialized transaction state notifications (of 'terminated' and 'destroyed') in case of transport error.
