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).

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

This reverts commit 97bd05cb.

This reverts commit 10b8297d.

with new IBM drives.

CASTOR start with lower case letters.

- Fixed missing allocationLength in INQUIRY commands
- Fixed misnamed struct member (typo)
- Introduced setU32 utility function to replace fromLtoB32 (retired)
- Replaced usage of ad-hoc structures with the automatically set classes
(SCSI::Structures::LinuxSGIO_t, SCSI::Structures::senseData_t).

This in particular includes fixing the remaining strict-aliasing issues.

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.

Lowercased/Upercased some namespace/class names for homogeneity.

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.

child function getSerialNumber was added.

Moved definition of compiler flags so they become active. This fixes the lack of debug info in SLC6.
Fixed superflous semicolon detected by -pedantic
Fixed sign correctness in various places.
Removed the use of LL suffix in 64 bits contants (they are not required).
Some documentation clarifications.

We use MODE SENSE(6) to query the tape information and then MODE SELECT(6)
to set parameters which we only change.

By default we only enable compression.

Added an exception launcher function to prevent repetive tests.
Clarified the error/exception handling strategy in the manual.

pretty print the meaning of the ACS/ACSQ couple.

We use READ POSTION command with data replay in SHORT FORM.

Tested with mhvtl.

We use LOCATE(10) CDB as CASTOR does.
Here we need castor.conf LOCATE_TIMEOUT environment (*to be implemented*)

Tested with mhvtl.
