cta::exception::NotAnOwner

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

    castor::utils::SmartFd

This class should eventually replace the folowing class:

bug #92460: tapebridged should gracefully shutdown a migration tape-session when tapegatewayd reports a disabled tape

Refactored the tapebridged daemon and created the following unit-test that
recreates this bug:

castor::tape::tapebridge::BridgeProtocolEngineTest::testMigrationToDisabledTapeUsingLocalDomain

The refactoring was necessary in order to create the unit-test.  During the
refactoring I modified the logging of the tapebridged daemon so that the very
first session error detected is always logged immediately.  This will help
debug problems in the future if need be.

This commit adds the followimng class:

castor::tape::utils::SmartOcciResultSet

This class was tested by the following test program:

test/castor/tape/utils/TestUtilsMain.cpp

Another major cleanup of the castor code targetting to drop all warnings due to the -Wextra flag. On the way, many little bugs were fixed (possible core dumps in command lines, wrong or missing checks, ...), code was dropped since unused, files were converted from dos to unix end of line convention, etc, etc ...

Simplified exception messages of the smart pointers of the tape::utils package.  This will help us use the code in the mighunter.

castor::tape::aggregator::SmartFdList to the castor::tape::utils package.
This has been done to prepare for the addition of the yet to be developed
castor::tape::utils::SmartFILEPtr which will be required to implement the safe
closure of the TPCONFIG file using the "resource acquisition is resource
allocation" approach.

aggregator_non_blocking, i.e. I replaced

    #include "castor/tape/aggregator/

with

    #include "castor/tape/aggregator_non_blocking/

aggregator.  For this reason we are creating the following new svn directory:

trunk/castor/tape/aggregator_non_blocking

This directory will be merged with the aggregator directory and deleted when the
work is over (sometime next year).

package contains code which should be common to all of tape.

side of the RTCOPY protocol.

Improved logging.

session.  We are still unable to do so, it looks like we need to
count both open connections between the recaller and rtcpd and the
number of outstanding active file copies.

DriveAllocationProtocolEngine.

The code compiles, but surely will not work.  A long way to go...

and function strings to tape exceptions.  Example usage:

  TAPE_THROW_EX(castor::exception::Internal,
    ": Failed to down cast reply object to tapegateway::FileToRecall");

  TAPE_THROW_CODE(EBADMSG,
    ": Unknown reply type "
    ": Reply type = " << reply->type());

Fixed bug in RTCOPY protocol; we were sending one too many "end of file lists".

Fixed bug in message dispatch logic, there was a missing break in one of the
switch statements that was causing an IObject to get dynamic casted to two
different classes.

  castor::tape::aggregator::VdqmRequestHandlerThread::run

The function is now nearly half its orginal size.

it will close the basic file descriptor it owns.
