Corrected helgrind errors by adding mutexes for multithread access to RecallReportPacker attributes.

Added files and bytes count for Retrieved files from User or Repack in the "tape session finished" message
Made the Repack system test clearer by printing steps and by adding folders for the reports

or write.

Implements setTapeMounted in the scheduler interface for RetrieveMount
and ArchiveMount.

Moved disk-operations-related code into the new "disk" directory

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)>).

of VO and Density"

This prevented the passing of exceptions as output.
Also integrated the promise in the reporter class.

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().

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.

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).

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).

Completed support for tape density and add usage of at() in a vector access to prevent segfault in unit test.
Removed some throw() specifications which led to segfaults.

The SchedulerDB provides a TapeMountDecisionInfo object, which contains all that the schduler needs to decide what
tape mount to start. The tape mount decision info then creates an archive or a retrieve mount with 2 separate methods.
The schedulerDB does not have a bare TapeMount class any more. On the scheduler itself will.

The bottom line is the Mount and Job classes shall be passed around the
tapeserverd daemon for two purposes, to carry all the information about
the file copy to be transfered and to provide the notification interface
to the scheduler on which the tapeserverd daemon needs to call methods
to indicate the ends of transfers and mounts.

Improved the readbility of the Scheduler code by replacing dynamic casts with the addition of a simple getMountType() method to the TapeMount, ArchiveMount and RetrieveMount classes

Moved mock scheduler DB in a separate directory to reduce the number of files per directory.
