the file is available and we are waiting for the response from the stager_get.

        Polish some of the debug messages.

Added error for killed sessions.
Added delay to protect against races between end of process and status update.
Added coverage for the unlikely event where a session finishes on its own while we intend to kill it for shutdown of timeout.

Fixed dropping of the Advanced Queuing items : ignore PLSQL errors that DBMS_AQADM must be declared so that the dropping does not fail on DBs where Advanced Queuing is not used at all

To forcefully dismount a tape means to rewind and eject the tape
where necessary.  This modification adds the ability to force dismount
to the MediaChangerFacade and the CASTOR acsd daemon.

Temporarily added the txtype parameter to the signature block. This part should be improved to support the optional castor.pool parameter, instead of just concatenating the (repeated) values

for a d2d transfer. The way the tokens are concatenated is important and should follow
the order specified in xrootd/XrdxCastor2Acc.cpp:BuildToken.

Dropped Client.secure from the transfers as it's never used - RFIO is unsecure, GFTP and XROOT are secure in all cases

Renamed castor2fs to castor for the URL parameters and added a pfn2 parameter to URLs for disk-to-disk copies
