fix: merge jcbf/add_bestguess branch with SPF best guess fallback feature

Merged the add_bestguess branch which implements SPF best guess evaluation
when no SPF record is found. This provides more robust SPF checking for
domains without explicit SPF policies.

Changes from jcbf/add_bestguess:
- Add SPF_GUESS_RECORD constant with fallback policy ("v=spf1 a/24 mx/24 ptr ?all")
- Add best_guess configuration option (default: enabled)
- Add is_best_guess flag to context struct to track when fallback was used
- Implement SPF_request_query_fallback() when SPF_RESULT_NONE and best_guess enabled
- Append "(SPF best guess)" text to Authentication-Results headers when fallback used
- Add SpfBestGuess configuration option in smf-spf.conf

Conflict resolution:
- Preserved VERSION "2.5.2" from master
- Kept all new features from master (SKIP_AUTH, SKIP_NDR, REJECT_REASON, etc.)
- Fixed typo: relaxed_locapart -> relaxed_localpart
- Integrated best_guess logic into updated SPF evaluation flow
- Used MAX_HEADER_SIZE for header buffers (from master)
- Used log_message() instead of syslog() for consistency with master

This allows administrators to optionally use SPF best guess for domains
without published SPF records, improving spam detection while maintaining
backward compatibility.
