Logger in rgoers/log4j2-api is too complicated.

                 Key: LOG4J2-39
                 URL: https://issues.apache.org/jira/browse/LOG4J2-39
             Project: Log4j 2
          Issue Type: Improvement
          Components: API
            Reporter: Ralph Goers

Curt added a @doubt to Logger that states "interface so complicated indepenent implementation
unlikely.  Should be refactored." and in AbstractLogger "See comments on Logger, interface
is so complex that unlikely to be independently implemented."  LogMF/LogSF separates those
concerns out of Logger.

An API is for the convenience of the caller, not the implementor. The API has many variations
of the same method for that reason. In addition, many of them exist simply to make the API
perform better as varargs, while convenient, perform poorly. In addition, the observation
that the interface is "so complex that it is unlikely to be independently implemented" is
unfounded. Creating a new implementation requires extending AbstractLogger and implementing
the log method and 8 isEnabled methods. That isn't terribly hard at all.
