If the loop is breaked, this means we've got a treatment error. We don't need to reconnect but we must exit with correct status.
This patch modifies the init of Detect threads. They are now started with a dummy function and their initialisation is done after the signatures are loaded. Just after this, the dummy function is switched to normal one. In IPS mode, this permit to route packets without waiting for the signature to start and should fix OISF#488. Offline mode such as pcap file don't use this mode to be sure to analyse all packets in the file. The patch introduces a "delayed-detect" configuration variable which can be use to restore previous behavior (set to "no" to have signature loaded first).
This patch add a early exit condition to the body handling callback. This permits to avoid to avoid a complex system to handle htp object change.
This patch converts the series of variable to an atomic. Furthermore, as the callbacks are now always run, it is not necessary anymore to refuse a ruleswap if HTP parameters are changing.

We come to this case when a SMTP session contains at least 2 mails
and then the ending of the first is not correctly detected. In that
case, switching to a new tx seems a good solution. This way we still
have partial logging.
