Subject: idt: add interruption handling

The Interruption Descriptor Table (IDT) is implemented in idt.{c,h} as
part of the core, but the setup and activation of the IDT and the
registration of specific interruption request handlers is part of
arch.{c,h}.  The request handlers are implemented in idt.s and
delegate to kernel_handle_interrupt.
