first step to make dbdma less hackish
- dbdma_alloc gets a new parameter to return the actual address of the
buffer before being alignment-mangled so we can properly free it
- add dbdma_free which takes the pointer mentioned above
dbdma should really use bus_dma

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Make macppc compile by default with -Wall -Wmissing-prototype in addition
to its currently enabled warnings. For the lack of a better place, most
global function prototype wound up in <machine/autoconf.h> unless there
was a better place for them. ofb_* structs renamed to offb_* to avoid
conflict with ofb_softc in <dev/ofw/openfirm.h>
