This time the fix is proper for issue 12284. I have tested it thoroughly and found

that valgrind no longer complains and that calls do complete correctly.

The fix is along the same lines as before: Make sure the final null terminator gets copied
into the new sip_request's data pointer. Without it, parse_request will read and potentially
write past the end of the string, causing potential crashes.

(closes issue #12284...for real this time!)
