Improve cpu_idle():
o cpu_idle_hook is expected to be called with interrupts
disabled and re-enables interrupts on return.
o sync with x86: don't idle when the CPU has runnable tasks
o have callers of ia64_call_pal_static() disable interrupts
and re-enable interrupts.
o add, but compile-out, support for idle mode. This will be
enabled at some later time, after proper testing.
