core: Changed HTTP_REPLY_HACK from a compile-time to a run-time option
- By default it is off, to turn it on set http_reply_hack=yes in kamailio.cfg
- You need to turn this on if you use xhttp _and_ event_route[sl:local-response].
This is because HTTP responses are stateless responses and when the
event_route is run it has to parse the response. Without HTTP_REPLY_HACK
Kamailio can't actually parse HTTP responses.
