When is a transaction created? Is it when any of t_relay(), t_newtran(), t_forward* functions run.
yes
If yes, then what method should we use t_newtran()?
use it for localy processed requests which you would like to process statefuly. That's particuarly meaningful if you wish to avoid repeated execution on retransmission either because the request processing logic is to heavy or for other reasons.
I'm assuming REGISTER should not get t_newtran() unless it is forwarded from a proxy to a location server, right?
I personaly don't think that REGISTER should use transaction state. Note that RFC3261 suggests stateful processing.
