Suricata

Issue 1412 described a situation with multiple buffers and byte variables.

Results are indeterminate and may cause issues when this occurs. Since there are existing rules that do this, it was decided for Suricata 8 that such usage will be
- Flagged as an error when --strict-rule-keywords is used
- Flagged with a warning message but permitted otherwise.

This ticket aims to resolve the indeterminate nature of the situation (see 1412) and provide full support for multi-buffer byte variables.
