Added core dump handler code

Fixed author Doxygen tag

Added licence headers

Moved return value definition to new header

Converted all DOS line endings to Unix

Solution for CPU dependency by using CMAKE_SYSTEM_PROCESSOR cmake variable

CPU specific stuff is implemented in own implementation file for each CPU architecture

Added config file for sysctl. Fixed wrong parameters to open call for lockfile

Added mechanism to overwrite TARGET_CPU_NAME with command line option
