Migrate from log4cpp to log4cxx This change is a wholesale removal of log4cpp from source tree. log4cxx is an external library installed via RPM, or user build to default /usr/lib64 and /usr/include directories. Some of the QRLogger and CommonLogger code was changed to use the new log4cxx APIs.
Cleanup of comments in log4cpp Copyright notices in log4cpp files needed some minor changes to make them 100% correct, since the rules for their copyrights are not the same as elsewhere in Trafodion. This is preparatory work before adding the source files for log4cpp to the packaged core product. Those files have small differences from the files downloaded from http://sourceforge.net/projects/log4cpp version 1.1.1, and so they should be provided to the end user.
