45219bce2e - huge commit 
- enable the paging support
- redesign of the APIC code

TODO:
- Currently, we are not able to start user-level applications.
- The RTL8139 driver does not longer work. Perhaps, a bug in the output function.
- The APIC codes doesn't work on all systems. Therefore, the code is currently disabled.
