Renamed CastorInstallSysconfig to CastorInstallSysconfigExample because the name should be based on what is installed, which in this case is an example file

I forgot to do commit -a on the previous commit.  Sorry

Fixed in the main branch.

CastorFile.nsOpenTime. Actually, the goal for next non-transparent
intervention should be to rename selectCastorFile() into
openCastorFile(), so that its scope is well defined, and the other
stager operations not needing an open() should just execute their
dedicated procedures. This should be in the scope of completing the
refactoring of the stager.

- Improved logging of the drainRunner job, and cleaned up old unused
messages.

(ORA-06550, PLS-00306)
This was due to a malformed (but legitimate) request where no argument
is given, and Oracle does not like empty buffers. Now the request
handler returns EINVAL straight away. Note that the C client API and
the stager ware already protected against such a case.

This was actually triggering deadlocks in production (CMS) with users
using non normalized paths. The deadlock was due to the autonomous
transaction in dropReusedLastKnownFileName() attempting to take a lock
on a CastorFile already locked by the main transaction, which is
forbidden.

Please not that these command-line tools will not be built unless the
following line of CASTOR/castor/tape/Imakefile is uncommented:

COMM include LOCAL_PATH/rmc/Makefile

Added compilation of the security plugins (except the apprently obsolete GSI one). Corrected the ID security plugin which was a duplicate of the KRB5 one. Correction also applied to imake system. castor-lib package is now complete. (Next in build order:  castor-transfer-manager.)

Please note that I have explicitly not ported the installing of the
tapegateway header files.  These headers files are currently installed by the
castor-build-headers rpm.  I beleive that they should not be part of the
castor-build-headers rpm in 2.1.15-x because the new tape server code will live
within the main CASTOR git repository and will therefore not need to have an
rpm such as castor-build-headers in order to construct a build environment
outside of CASTOR.

tapebridged binary.

Please note that for the time being castor/tape/CMakeLists.txt will not add
castor/tape/rmc/CMakeLists.txt as a subdirectory.  The line doing this is
currently commented out.  This is because the three following executables are
not yet part of an offcial CASTOR release:

    castor-tape-acs-dismount
    castor-tape-acs-mount
    castor-tape-acs-queryvolume

Added a manual page for the command-line tool named castor which is used to display the current CASTOR version.
