CASTOR-5042: The SCSI layer of the tape server overlooks SCSI errors
not coming from the target

Fixed.

Add output for all errors available for SCSI call.
The logic implemented is to go through all errors in the following
order: status, host_status, driver_status. In case of particular
error an appropriate exception generated.

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

on SCSI call TEST UNIT READY instead of st driver.

Reiplemented drive::DriveGeneric::waitUntilReady to use TEST UNIT READY
SCSI command.

Fixed inheritance from std::exception (const correctness of what()). This required declaring m_what mutable.
Created a multithreaded unit test.
Created an automatic exception thrower for unhandled errors.
Ported from previous proof of concept the threading primitves and made them production level (with error checking).
Added unit tests for threading primitives.

Removed the now duplicated backtrace and adapted the code where needed.

Removed the author list from every file and added the complete list into a single file.

Clarified the error/exception handling strategy in the manual.

Updated the contents of the test harness for SCSI device listing.
Updated the expectations of the device listing test (now passes).

Unit test does not pass yet.

Completed a first test harness based on a system wrapper, simulating sysfs and 3 generic scsi devices.
Created test using the harness.
Created SCSI::DeviceVector class, listing the devices on the system.
