Renamed CTA/tapeserver/castor to CTA/tapeserver/castor_checkout in preparation for the moving the sub-directory CTA/tapeserver/castor/castor up the directory tree

 The full set of packages can be compiled straight with the following sequence:
   rm -rf ../build/; mkdir ../build; (cd ../build/; cmake ../castor-git/ ); make -C ../build/ castor_rpm
 The client packages can also be build directly by adding an option at cmake time:
   rm -rf ../build/; mkdir ../build; (cd ../build/; cmake -DCOMPILE_SERVER:STRING=0 ../castor-git/ ); make -C ../build/ castor_rpm
 Finally, one can use the srpm as a first step, and use the TeamCity compatible rpmbuild switch "clientonly":
   rm -rf ../build/; mkdir ../build; (cd ../build/; cmake ../castor-git/ ); make -C ../build/ castor_srpm
   buildtree=`mktemp -d`; mkdir -p ${buildtree}/{RPMS/{i386,i586,i686,x86_64},SPECS,BUILD,SOURCES,SRPMS};
   rpmbuild --define "_topdir ${buildtree}" --define "clientonly 1" --rebuild ../build/RPM/SRPMS/castor-2.1.14-4.el6.src.rpm

Fixed incomplete variable renaming. Fixed tarball naming mish-mash in SLC6 (needed rpmbuild's %dist appended.

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

Added options to the srpm building like in TeamCity. The srpm gets compiled in SLC6 and did not compile to RPM in SLC5 (all fine in SLC6)

2 new targets are added: tape-server_rpm and tape-server_srpm
