Summary: New function registered_from in module registrar 

Initial Comment:
I have a requirement to only accept requests from UAs that are currently registered. And the ip:port from the request must be the same that was used in the registration (received_avp).
So I have written a function registered_from (based on function registered) that will receive parameters location, AOR and URI-received (all required), and will return true if:
  - string received="scheme:ip:port" is found inside ucontact->path
or 
  - ucontact->received equals URI-received

Examples of use:

                $var(received) = "sip:" + $si + ":" + $sp;
                if(!registered_from("location", "$fu", "$var(received)")) {
                        sl_send_reply("404", "Request not from registered UA");
                        exit;
                }
		
                if(!registered_from("location", "$fu", "$hdr(User-Received)")) {
                        sl_send_reply("404", "Request not from registered UA");
                        exit;
                }

I have generated the patch from branch 1.6 which is the one I am currently using but I can regenerate it from trunk if necessary

regards,
Takeshi
