sys: use our nitems() macro when param.h is available.

This should cover all the remaining cases in the kernel.

Add locking to the aic(4) driver and mark it MPSAFE.
- Move 'free_scbs' into the softc rather than having it be a global list
and convert it to an SLIST instead of a hand-rolled linked-list.
- Use device_printf() and device_get_unit() instead of storing the unit
number in the softc.
- Remove use of explicit bus space handles and tags.
- Don't call device_set_desc() in the pccard attach routine, instead
set a default description during the pccard probe if the matching
product doesn't have a name.

Prepare for future integration between CAM and newbus. xpt_bus_register
now takes a device_t to be the parent of the bus that is being created.
Most SIMs have been updated with a reasonable argument, but a few exceptions
just pass NULL for now. This argument isn't used yet and the newbus
integration likely won't be ready until after 7.0-RELEASE.

o break newbus api: add a new argument of type driver_filter_t to
bus_setup_intr()

o add an int return code to all fast handlers

o retire INTR_FAST/IH_FAST

Turn on interrupt-entropy harvesting for all/any mass storage devices
I could find. I have no doubt missed a couple.

Interrupt entropy harvesting is still conditional on the
kern.random.sys.harvest_interrupt sysctl.

Add module dependencies on CAM module.

Terminate aic_ids[]

- Added PC-98 Cbus frontend.
- Move dev/aic/aic_isa.c entry from conf/files to conf/files.MACHINE
because PC-98 uses different file.
