Non-deterministic behavior when encountering duplicated SIDs

Description

Long story short, because suricata-update reads commented-out rules in addition to normal rules, things get really weird if you have one .rules file with a SID commented out and a separate .rules file without it commented out, and doubly so if you're trying to threshold those rules using threshold.in.

I was doing this as a way to enable rules that were commented-out by default in rulesets that I downloaded, rather than by modifying the files each time they were pulled down.

We should probably fire off a warning or something if suricata-update encounters a SID that it thinks it already knows about.

  • Target version set to 1.0.0b1

I plan to add preference to the rule with the highest revision and log an info or warning message when encountered. I’ll do this sooner than later to make it deterministic before the next release.

Since you've mentioned you'd address this before the next release, I thought it'd be safe to assign it to 1.0.0.

Jason, maybe because this was done in https://github.com/OISF/suricata-update/commit/6c87a153bc1b011acdb16dbc17bd1fea07948220 ?

Ok. Works for me.
