c738a64d57 integration of RCCE in MetalSVM (untested version) 
Attention: currently, MetalSVM didn't support the floating point unit

=> no using of RCCE_wtime
=> no using of the data type RCCE_double
=> RCCE_init expect an integer value as frequency in MHZ

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.
