[Users] NEW FEATURES: t_replay() enhancements

[Bogdan-Andrei Iancu]

Hi everybody,

following several discussion threads from some time ago, I added a 
support for controlling the behaviour of t_relay() functions. This 
addresses:

1) to ability to stop t_relay() from automatically sending the 100 
trying provisional reply before relaying the request. This is useful in 
scenarios where you already send a stateless 100 trying from the script.

2) ability to do serial forking in failover scenarios - as original 
t_relay() automatically sends a negative reply in case of a failure 
(unresolvable URI, TCP connect refused, etc), it was impossible to 
continue with the next destination. Now, the auto-reply can be disabled.

backward compatibility is kept.

For more details (how to do it, options, etc), please see the online docs:
