Adapted the tape code.
Moved the Errnum unit tests and covered all the throwers.

Partially added signal handling system for the single threaded daemon.
Cleaned up the local daemonize() function.
Added exception throwing helpers for standard error situations.

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.

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.

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

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 stack trace support for exceptions (with C++ name demandling).
Added more anaysis of the past code in documentation.

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.
