Drop the first argument of intr_establish().

Instead, require all callers to put the right value in the ih_pil field, and
have intr_establish() trust them rather than assigning this field again from
its first argument.

Rework vbus(4) interrupt handling to be similar to cbus(4). Expose functions
to ack and enable/disable interrupts and don't enable interrupts by default.
Also don't ack interrupts by default.

Make use of this in vcons(4) to avoid interrupt storms that may occur
because of a race between the interrupt handler and the software
interrupt handler. Don't enable the interrupt handler unless somebody
actually has the console open. Ack the interrupt at the end of the softintr
handler.

Fixes console issue on SPARC T3 machines.

If we use the cookie-based interrupt API on sun4v, whe shouldn't put the
interrupts in the lookup table. On machines like the Oracle T7-2 this
would make the code believe that there is interrupt sharing, but since
we bypass intr_list_handler() when using the cookie-based interrupt API,
we wouldn't properly acknowledge the interrupt.

This fixes the last remaining problem with interrupts on the Oracle T7-2.

Implement support for using interrupt cookies in vbus(4) and vpci(4) as
introduced in version 3.0 of the Interrupt APIs group. This makes it possible
boot OpenBSD on SPARC T7/M7 hardware (although there still may be issues with
the onboard mpii(4) controller).

Store the target CPU in "struct intrhand" and use it in intr_barrier().
Also use it wherever we configure the hardware to direct interrupts to the
right CPU.

add a size argument to free. will be used soon, but for now default to 0.

Add support for BUS_INTR_ESTABLISH_MPSAFE. This makes the previous commit
to vcons(4) actually have an effect.
