Removed DataTransferSessionEmptyOnVolReq unit test which now locks (sessions now loop until they schedule).

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).

      to the SCSI metrics log lines.
    ## Changes
      * Add the line to the logs
      * Modify session test to check existence of the property in the log

  Move volume SCSI statistics inside the dtor of TapeCleaningMove volume
    SCSI statistics inside the dtor of TapeCleaning

  ## Description

  When first introduced volume SCSI Statistics (at the moment
  IBM-specific), we explicitly put the function after the unmount of the
  tape was done due to an invalid file descriptor error occurring during
  the SCSI query.

  This bug no longer occurs for IBM drives.
  This may be attributed to the update of firmware of the IBM drives

  Apart from the change of the position of the changes, there is no
  alteration in terms of the metrics reported from the drive to the logs.

  ## Testing

  The tests the new code has been through are:
    * Write/Read file on IBM lib0 drive *(older one)*
    * Write/Read file on IBM lib4 drive *(newer one)*
    * Write/Read file on Oracle T10k drive

Replaced castor file header with CTA file header

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

cta::server::ProcessCap

Ported DataTransferSessionTest unit test DataTransferSessionMissingFilesMigration and DataTransferSessionTapeFullMigration.

Also fixed tapes not being set to full when reaching end of tape.

Ported DataTransferSessionTest unit test  DataTransferSessionGooddayMigration and DataTransferSessionEmptyOnVolReq.

Ported another DataTransferSessions unit test (DataTransferSessionWrongRecall) to the new scheduler.

This commit also enforces the interdiction of empty strings being
bound as string database parameters.  Either a non-empty string is
bound or no value at all is bound (nullopt).

Re-enabled the unit test, which does not leak memory (but logs errors instead).

Fixed libraby linking which led to multiple initialization of static variable (detected by valgrind's drd).
Worked around cmake's failing dependency management for generated protocol buffer sources (double make in spec file).
Partially fixed the first data transfer session unit test (still disabled).
Fixed a typo in an error message.

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).

from castor in the exercise.

This implied removing tpconfig, tplabel and tpstat.

Removed archive and retrieve to directory requests.

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

Fixed namespace not matching other files in tests.

Added rados library version validation and cleanup.
Created a new shared library to ensure instantiation of singleton object supporting the former.
Removed several double creations of drive objects in unit tests.
Added cleanup for potentially unused drive objects in unit tests.

Added url style conversion of checksums
Added support for checksums in mockNs
Fixed support for checksums in the scheduler
Re-instated several ASSERT_NO_THROW which were commented out during debugging.
