New framework for handling processor interrupts, derived in part from

Browse Source 
the hp300 port.

- Interrupts 3-6 use this immediately.  Interrupt 7 is a special case,
and the VIA interrupts (1 and 2) will be addressed when that code is
rototilled.

- Modify the zs front end to register with the appropriate interrupt
controller:  through the PSC on the AV Quadras, and direct to
interrupt 4 on the rest.  Arrange to have the appropriate zsc_softc
supplied to us at interrupt time.

- Modify the direct ADB driver (and its PowerManager cousin) to call
intr_dispatch(), rather than zshard().  XXX This is a kludge, but at
least limits the brokenness to the ADB drivers, now.

As a side effect, this should fix PR 5590.  Thanks to Bill Studenmund for
correctly determining the cause of the problem reported there.
