That way, the LogContext is no longer shared between different threads

The code was duplicated just bellow

A shared thread safe variable counts the number of failled writtings and we call reportEndOfSessionWithError at the end if needed

From void to bool : true if the file has been successfully written false otherwise

and thus changed the type to an auto_ptr into DiskWriteTask

Changed the constructor to take that into account and its calls in several files

RecallReportPacker is provided as a parameter of execute, and the opther attributes have been replaced by a FileToRecallStruct

Conflicts:
	castor/tape/tapeserver/utils/suppressUnusedVariable.hpp

Changed the constructor to take that into account, and changed the calls to the constructor where it was needed

Conflicts:
	castor/tape/tapeserver/utils/suppressUnusedVariable.hpp

Fixed the removal of #ifndef GLOBUS_DONT_DOCUMENT_INTERNAL from previous commit in security headers.

The script used to switch to #pragma once got fooled by their unusual structure.

Fixed h/rfcntl.h which missed multiple inclusion guards entirely.

Added first attempt to insert a real writting in a DiskWriteTask. CMakeList changed to add the File library to the tapeserver one

Cleaned up interfaces to removed endOfWork remains and make functions virtual pure when it was possible
