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)
