Existing SMP apic code improvements
* i386/i386/apic.c (acpi_get_irq_override): New function.
(apic_get_ioapic): Make it return IoApicData* rather than IoApicData.
(apic_print_info): Manage IoApicData* rather than IoApicData.
* i386/i386/apic.h (struct ApicReg): Use uint32_t instead of unsigned.
(struct ioapic_route_entry): New structure.
(union ioapic_route_entry_union): New union.
(ApicLocalUnit): Rename base to gsi_base. Add ioapic field.
(APIC_IRQ_OVERRIDE_POLARITY_MASK, APIC_IRQ_OVERRIDE_TRIGGER_MASK): New
macros.
(acpi_get_irq_override, ): New prototype.
(apic_get_ioapic): Update prototype.
(lapic): New declaration.

LAPIC_ENABLE, LAPIC_NMI, LAPIC_DISABLE, LAPIC_TIMER_PERIODIC,
LAPIC_TIMER_DIVIDE_2, LAPIC_TIMER_DIVIDE_4, LAPIC_TIMER_DIVIDE_8,
LAPIC_TIMER_DIVIDE_16, LAPIC_TIMER_BASEDIV, NINTR, IOAPIC_FIXED,
IOAPIC_PHYSICAL, IOAPIC_LOGICAL, IOAPIC_NMI, IOAPIC_EXTINT,
IOAPIC_ACTIVE_HIGH, IOAPIC_ACTIVE_LOW, IOAPIC_EDGE_TRIGGERED,
IOAPIC_LEVEL_TRIGGERED, IOAPIC_MASK_ENABLED, IOAPIC_MASK_DISABLED): New
macros.
* i386/i386at/acpi_parse_apic.h (struct acpi_apic_ioapic): Rename base
field to gsi_base.
* i386/i386at/acpi_parse_apic.c (acpi_apic_add_ioapic): Update to
gsi_base new name. Set ioapic field.
(acpi_apic_setup): Rename lapic to lapic_unit.
