This is the next part of the migration to Flogger. This change migrates
all classes of the 'pgm' module to Flogger. Classes of most other
modules have blready een migrated by predecessor changes. Some remaining
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(...)
