Message:

merge small NE2000 and interrupt handling improvements

• introduce new uspace interrupt controller drivers
  • i8259
  • APIC (only a non-functional stub yet)
• do not pre-enable NE2000's IRQ in kernel, but use the above drivers (solves the "spurious interrupt" issue, but breaks SMP functionality because of the non-functional APIC driver)
