This commit does two things.  Firstly it adds the first version of the source
code for the executables to help the rmcd daemon to work with Oracle ACS
compatible tape-libraries.  Secondly it refactors and cleans up some of the
rmcd daemon code.

Please note that the source code of the binaries to help the rmcd work with
Oracle ACS tape-libraries is neither compiled or packaged into rpms.  Therefore
there will be no affect on the current 2.1.14 release concerning these
executables.
