Replace logging infrastructure with Log4j

Replace logging infrastructure with Log4j

- Remove the existing logging infrastructure and replace it with the
  Log4j Scala API. Log4j Scala API and Log4j API are added as
  dependencies. Log4j Core is added as a test dependency and a CLI
  dependency. Users of the Daffodil API are expected to manually add
  log4j-core or some other Log4j implementation to enable logging
- Distribute a Log4j configuration with the CLI to maintain a similar
  log outut as with the previous implementation
- The Scala/Java API logging functions are deprecated and are now
  no-ops. The functions were not thread safe and could lead to random
  test failures. Logging tests are removed--we simply use the API and
  rely on Log4j testing for correctness
- We no longer have the different log levels as before, we know just
  have error, warn, info, debug, and trace
- Modify .sh and .bat files to be consistent and add a more clear way
  to set default java options that can be overridden by the user if
  needed
- Minor refactor of UDF to improve logging and allow warn+ignore
  provider loading errors
