8a707cf2bd The procedure name "network_shotdown()" did indeed sound a bit too 
violent, so i renamed it to "network_shutdown()", just like the header
file says.

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.
