Remove the common TapeJob class as there is little to share between the ArchiveJob and the RetriveJob.
Their similarities are more in concept than implmentation.
Added an ArchiveFileInfo class to hold the location an properties of the archive file we are working on.
Add an ArchiveFileInfo member to the ArchiveJob.

Added to RetrieveJob the fields used by tapeserverd in castor::tape::tapegateway::FileToRecallStruct.

Started the creation of the mount decision process, where the scheduler extracts the potential mounts from the database before sorting, filtering and deciding which one will be started.

Introduced the scheduler to the DataTransferSession, replacing the concept of DGN with logical library

The master process of tapeserverd now launches a transfer session process every 10 seconds whilst the corresponding drive is idle (DRIVE_STATE_UP)

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.

Removed the classes responsible for implementing the RTCOPY protocol from the CTA version of tapeserverd

Removed the classes responsible for communicating with the cupv daemon from the CTA version of tapeserverd

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

Removed the TapeSession class because it appears that Eric replaced it with the TapeMount class but forgot to delete it

Please note that you will have to install the following CASTOR rpms
in order to compile:

  castor
  castor-devel
  castor-lib
  castor-lib-server
  castor-lib-tape

Also organised common in subdirectories, and added sub directory for mockDB.
