core: added timeval field inside sip_msg_t

- new parameter msg_time to set the timeval value at receive time (1
  (on) by default, set to 0 to disable)
- the value is set automatically at received time based if msg_time=1 or
  first time when it is accessed
- the field should bring coherence regarting time of the message - it
  should be the same no matter where is processed
