- Assorted style fixes and minor changes.
- Allow multiple INTR_FAST handlers for the same source. The motivation
  for this are the on-board SCCs and UARTs that use a shared IRQ.
- Rework the interrupt counting code to account for shared interrupts.
- In case ithread_add_handler() failed in inthand_add() just return with
  the error code instead of setting up a non-fast handler regardless or
  setting up a non-fast handler instead of a fast handler. I can't think
  of a situation where the former behaviour would do the right thing.
