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.

pretty print the meaning of the ACS/ACSQ couple.

(CASTOR way was just to fill everything with 0)

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.

As soon as mhvtl does not support LogPages 32h and 38h it is not tested.

Added senseData structure, which is polymorphic, and added unit test.

Changed all the char arrays used as storage to SCSI number into unsigned char[] (we were in a mixed situation).
Added unit test for the recently created structures.
Replaced shift and or with toU16 in log select unit test.
Added reference to st man page and txt file in documentation.
Changed signature of getTapeError.

Added sg_io_hdr_t wrapper to avoid boilerplate code.
Templated tapeAlertLog structure to make its use safer an added zeroing to it.
Minor documentation clarification.
Updated getTapeAlerts to use new SCSI structures.
Added new function signature: getTapeError.

Added support for log sense command.
Added support for tape alert log, with convertion from code to string.
Updated test harness to support ioctl overloaded.
Fixed some formatting in the doc.

Turned the inquiryCDB struct into a class, with auto setting of the opcode (which is always the same) and adapted the usage.

Changed Tape::Drive's behavior to open nst instead or st and adpated test environment.
Changed Exception::what() as it returned pointer to a destroyed stack-based objet. Introduced a setWhat function and made m_what private to adapt.

Added a few conversion utility functions for handling the strings from devices, and the 
big endianness of SCSI. Added a test to validate both.
Added a dump for all fields of the tape drive's inquery response.
