- introduced recently in these log format changes.
- require_once 'ykval-config.php in logformat()
did not import, because it takes place in ykval-verify.php.
- hence logformat() did not have $baseParams in scope,
so we never write the log line.
- refactor and set format outside the class itself.
- Traditionally we wrote two lines for each ykval-verify.php call,
'Request:' and 'Response:'.
- This commit allows us to log both request/response values in a single line.
- For backward compatibility, the old logging is kept in place.
- To write this line to syslog, __YKVAL_VERIFY_LOGFORMAT__ needs to be set.
