Some legacy utilities from castor were imported alongside, with some adaptations.

There will be separate rmcd and acsd daemons, therefore
removing the need for an rmcd "super-daemon" that does both
SCSI and ACS.

Added FindOracle. Added include for generated header file. Added first sub-directory include.

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.

Reverse committing 25579:25519 because the revissions from 25520 to 25579 were too detailed.  They were meant to be a single revision pushed from my git repository.  The --merge option git svn dcommit did not do what I expected.

Now ignoring mountacs, dismountacs and queryvolumeacs in the correct directory, in other words in castor/tape/rmcd

Ignoring the existence of the smc binary in the rmc directory as opposed to its old location in the tape directory

Sorted the contents of the .gitignore file and added some "stk" and "nostk" artifacts that need to be ignore, for example "tape/mounttape-nostk".
