  Add proper support for dummy sip msg's

The dummy sip messages are used when there is the need of running a script route, but without actually having a real SIP msg, like for event_routes, startup routes, timer routes, etc.
This new support is solving two problems:
* the dummy message is actually a proper/complete SIP message, with all the mandatory sip headers. This prevents crashing when "reading" something (that is expected to be there, like the callid) from this SIP message.
* this is a global support, meant to be used from all the places, replacing the local implementation (from like 4 different modules/places)
