Doczom 85ae0c8703 Kernel: The APPDATA.debugger_slot field has been changed to APPDATA.debugger_thread 
The APPDATA.debugger_slot field has been changed to APPDATA.debugger_thread. The API for the internal functions of the kernel has been changed. Mathematical expressions have been replaced with constants and the code has been cleaned up.
