This is the second part of the migration to Flogger. This change migrates all classes of the 'server' module to Flogger. Classes of the 'httpd' module have been migrated by the predecessor change. Other modules continue to use slf4j. They should be migrated by follow-up changes. During this migration we try to make the log statements more consistent: - avoid string concatenation - avoid usage of String.format(...)
