Implement catalogue createDiskSystem,
getAllDiskSystems, deleteDiskSystem methods.

Replaced the map of tape files with a list as the assumption that we have one copy per copyNb is no more valid with repack.

The retrieve requests now carry all the information necessary to create the archive jobs.
Retrive requests carry an isRepack boolean. The distinction between repack and non-repack behaviour
is pushed as low as possible in the api (in the object store) so that client code can be more
generic. For the same reason, the
The expand repack mode (re-creation of missing tape files) is not supported yet.
Changed the represenation of copy numbers to uint32 (as this is the smalled number supported but protocol buffers).
Added ArchiveRoute::StorageClassMap and ArchiveRoute::FullMap to store archive routing in memory.
Added repack buffer base URL support, and mechanism to compute temporary copy location in disk cache.
Fixed bug in ObjectOps<>::asyncInsert();
Inplemented the path generation for repack disk storage (<BaseURL>/<VID>/<FSeq (09%d)>).

Because ToReport queues need to construct RetrieveJob objects which are
not associated with a mount

Successful retrieve requests are asynchronously deleted as soon as they
are complete. Then from time to time (every 500), the requests get removed from
process ownership in bulk.

Removed all instances of RetrieveMount::getNextJob() and siblings.
Fixed incomplete deserialization of archive file in RetrieveRequest::asyncUpdateOwner().

... in preparation for replacement of RetrieveMount::getNextJob().

drive.
Change frontend reporting for the current stats from bytes to Mbytes and
from bytes/s to Mbytes/s.

recall tape transfer session.

TaskWatchDog pereodically update Object store information with
current values for the tape session stats.

If the drive is set to force down mode, we stop finding new jobs and let the current session drain.

This object (with thread) already reports data movement to the main process, and will
also store it in the object store (interface will be added to TapeMount.

This was used for switching between xroot and rfio in CASTOR. Rfio is not supported in CTA.

Added drive status reporting in scheduler
Added drive status reporting in OStoreDB
Added support for drive status listing in the front end
Removed virtual functions from the Scheduler, which is never overloaded.
Added DesiredDriveState structure to drive state.
Removed usage of duplicate MountType, DriveStatus and DriveState structures.
Created DriveInfo structure to allow recreation of drive register entry in all
reporting situation (potentially with partial/assumed info).

Added a configuration parameter for Xrootd timeouts in tapeserverd.

Replaced castor file header with CTA file header

Moved castor::server::
  BlockingQueue
  Semaphores
  AtomicCounter
  AtomicFlag
into cta::threading::

Completed changes so that archive and retrieves can be queued, mounts created and jobs reported done.

Removed deprecated structures from archiveNS and nameserver namespaces. Removed RetrieveToFileRequest.

Started morphing the code to accomodate both the move some data structure from OStoreDB to catalogue and shared structures modifications.
Renamed class members using underscode instead of mixed case.
Removed mount criteria from in-memory tape pool representation.
Removed support for path of archive files for in-memory representations.
Removed all but maxDrives allowed from in-memory representation of mount
policy.
Created new constructor for UserIdentity.
Switch the UserIdentity used by RemoteFileStatus.
Renamed TapePoolQueue to ArchiveQueue.
Replaced CreationLog usages with EntryLog.
Renamed TapeQueue to RetrieveQueue.
Removed support for data now gone to catalogue from RootEntry.
Removed corresponding structures from object store.
Removed corresponding calls from SchedulerDatabase and inheriting
classes (OStoreDB).

Extracted common forward definitions into a single include file.

Removed unecessary old code, including propagation of the moved port
Put inplace "make unittests" which now run the unittests through valgrind and helgrind.

The report packer should now also be referenced in the tape recall thread, so it can report the drive status.
testingMocks/MockRetrieveMount.hpp needs to be improved so it handles les end of session correctly.
Then the mechanism has to be mirrored in Archives (simpler case).

Fixed confusion between archive and retieve in logging "path" and creation of file object by file factory.

Removed mocking of classes where functions have non-copyable argumentes (unique_ptr).
Replaced NULL references to watchdogs to dummies where necessary.

Adjusted unit test to accomodate the new structure (SchedulerDatabase::RetrieveMount is now a pure virtual class).

Removed usage of the mock scheduler database that will not be updated for further modification in the scheduler database interface.

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
