Description

pmq has 2 arrays:

1 pattern id array
2 pattern id bitarray

1st is only used in proto detect and not at detection engine runtime. We need to remove it for efficiency.

the pattern_id_array is used by the proto detection to retrieve the id.

Maybe we can have some compromise between the detection phase that doesn't use the array, and the proto detection phase that needs it.

Probably pass some flag to the mpm.

Profiled this by removing it from ac. See no noticeable difference in perf.

I suggest we continue using this.
