The exception class named castor::exception::Exception provides the same
functionality as castor::exception::Internal and therefore one of them
had to go for the sake of removing redundant code.

Added logging for the invalidation of diskCopies due to overwrites in another stager. Also fixed missing gcType in several places

Dropped more code related to compatibility mode. The configuration entry in CastorConfig stays to ensure 2.1.14 Stagers run with a 2.1.15 Nameserver

With our current understanding we see no reason for an exception from the
reactor to be used as a reason to stop the tapeserverd daemon.

In the future, one or more specific exception types could be introduced
with their own catch clauses that do in fact require the tapeserverd daemon
to be stopped.

Added a skeleton for TapeserverProxy::tapeUnmounted and tapeMountedForRead. To be completed by  Daniele and Steve

Pakcaged the new tape server in an RPM and added the option to not run the unit tests to hasten the build for development environements.

Changed 'path' of files within data pools so that they do not have the extra directory that is the fileid%100
