Initial work towards supporting IO APICs. This cannot work for PCI interrupts

Browse Source 
though until we use ACPI for proper PCI IRQ routing through the IO APIC.
Therefore the IO APIC code path is not yet enabled and the IO APIC isn't used.
ISA interrupts would work though, as would PCI interrupts if you'd hardcode
them for your specific configuration.
Note that this change also modifies some parts in the bootloader and in the PIC
setup to make local APICs available even on non-SMP systems. This causes APIC
timers to be used instead the normal PIT if it is available (also on non-SMP
configurations).
Also fixes some general errors in SMP and PIC code as well as some code cleanup.
