Remove uneeded bus_space_barrier() calls.

- Use aprint*() instead of printf() in xxx_attach().
- Add missing aprint_naive("\n");
- KNF

KNF. No functional change.

Split device_t/softc of i82586. No crash on TME emulating sun2.

struct device * -> device_t, no functional changes intended.

struct cfdata * -> cfdata_t, no functional changes intended.

ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.

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.)
