Motivation: Linux's prio_heap.h is of fixed size. Litmus's binomial
heap may be overkill (and perhaps not general enough) for some applications.

Implemented in the style of linked lists.

Increment a processor-local counter whenever an interrupt is handled.
This allows Feather-Trace to include a (truncated) counter and a flag
to report interference from interrupts. This could be used to filter
samples that were disturbed by interrupts.

Preemption state tracing is only useful when debugging preemption-
and IPI-related races. Since it creates a lot of clutter in the logs,
this patch turns it off unless explicitly requested.
