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

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

Added a new m_moverHandlerPort member to the diskFileFactory class, so the new xroot-c2fs URLs can be implemented.
Propagated the value from castor.conf through the constructors of the DiskThreadPools and the DataTranferSessions.

Propagated references to the watchdog to disk and tape threads and tasks.
Added a maps for storing the count of all errors that occured during the session.
Added propagation of the counts to the initial process.
Added error reporting in disk and tapes threads and tasks by using a string marker
allowing to know which part went wrong in high level exception. Exceptions then
bumps up the count in the watchdog (synchronously), and the watchdog sends the
new count to the initial thread later (in the watchdog's thread).
Plus some missing logs fixed when an exception is thrown in a disk write task.

Added interface to reference the recall watchdog to the recall disk thread pool.
Next: Do same for migration. Actually store the reference. Add new error map storing in watchdog. Add error reporting in tape and disk threads.

WIP: Added missing file ID for disk write thread. Added missing error log when an exception is thrown in a disk write task.

WIP: switching to CASTOR-4839 tapeserverd: task injector should decide on closing the session earlier

WIP. Next: log unmount errors (in the RAII)

Finished error counting in data threads.

The offending message has been changed in a previous case: CASTOR-4749

Reviewed all bandwidth calculations to homogenize the statistics printing.
Fixed a bug where the total time for a session was not properly retrieved before logging, leading to NaN printouts.

CASTOR-4739: tapeserverd should support localfile, rfio, xroot and rados striper access for disk files

Moved the call to getConfEntString(XROOT, PrivateKey, /opt/xrootd/keys/key.pem one step up to allow
unit testing in environments without a castor.conf

Tapeserverd now support file://, root:// rfio:// and radosStriper:// URLs, on top of heuristic protocol guessing from the hostname:[/]path synthax.
The rados striper version is not yet fleshed out yet.
The xroot client used for this is the latest object oriented client (XrdCl::File).

Fixed unnecessary virtual declarations in classes without inheritance (only detected by the SLC5 compiler).

Removed interface classes DiskReadTaskInterface, DiskWriteTaskInterface, DiskThreadPoolInterface

Otherwise, there was a race condition between the control thread and the worker threads.
Now, the log context of the worker thread is passed and used by popAndRequestMore.

and DiskReadThreadPool

Renamed member variables to canonycal m_
Renamed TaskInjector->end to TaskInjector->finish() to match other threads conventions.
Fixed missing finish() in RecallTaskInjectorTest
Added missing finish() call in TapeReadTSingleThread.

setTaskInjector, popAndRequestMore have been created and m_maxBytesReq,m_maxFilesReq have been added to be able to call TaskInjector::requestInjection

DiskReadThreadPool::WorkerThread::run has been changed consequently

DiskReadTask -> DiskReadTaskInterface, DiskReadFileTask -> DiskReadTask, same thing for the write side. Changed the includes files accordingly

and refactor a bit of code into the interface

We are now using the matching files and classes frpm castor/tape/threading
