Made direct transfer from ACTDEAD to USER optional. By default we do that state change via reboot. USER to ACTDEAD transfer was made optional laready earlier.
If direct transfer between USER <--> ACTDEAD is wanted then one has to define DSME_SUPPORT_DIRECT_USER_ACTDEAD while compiling. I didn't add any configuration switch to support that. Can be done when this direct transfer is wanted to get active if ever.
