Add support for local APIC hardware-assist.
- Restructure vlapic access and register handling to support hardware-assist
for the local APIC.
- Use the 'Virtual Interrupt Delivery' and 'Posted Interrupt Processing'
feature of Intel VT-x if supported by hardware.
- Add an API to rendezvous all active vcpus in a virtual machine and use
it to support level triggered interrupts with VT-x 'Virtual Interrupt
Delivery'.
- Use a cheaper IPI handler than IPI_AST for nested page table shootdowns
and avoid doing unnecessary nested TLB invalidations.
