810b13f37e - use the function lapic_read instead of direct memory access to the apic entries

9d2b73c6cb - add a workaround to use paging and the apic at the same time 
(we don't use __attribute__((optimize(0))))

8646b56a63 - minor changes to support APIC 
(currently, we got page fault by entering apic_calibration)
- first steps to realize a loader

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.

- If an a APIC is available, the PIC timer will be disabled
- SMP is currently not supported
