- Rename driver.intf.serial -> driver.io.serial (intf/ -> io/)
- Move net protocols to driver.net.proto.* (net/ -> net/proto/)
  - arp, dhcp, eth2, icmp, ipv4, tcp, udp
- Move netdev to driver.net.dev.* (netdev/ -> net/dev/)
  - e1000
- Move driver.net.pas into driver/net/
- Move driver.video.pas into driver/video/
- Rename arch.x86.faults -> arch.x86.fault, move to fault/ dir
- Move driver.storage.ctl.ahci.pas into ctl/ahci/
- Move driver.storage.ctl.ide.pas into ctl/ide/
- Move linker.script and version to toolchain/
- Update all unit references and namespace doc
