Suricata

Current master situation :
app-layer data does not get logged for frames, since commit 2b4e10224eaebb613352e9b82556b60035d032a1
Before that, and in main7, app-layer data gets logged, but we log tx id 0 if no specific tx was specified.

Also, the lack of tests suggest that there are many protocols which do not set the tx id for their frames...
Which may be due to the unfriendliness of the rust API to create anew frame with a known tx id...
