- Split X-Surf driver from if_ne_zbus, rework, add support for clockports present on X-Surf boards.
- Add gencp(4), a driver for generic clockports (it just needs a base address).

Approved by phx.

Workaround for the fake X-Surf autoconfig entry, created by the Deneb firmware v11.

Change <machine/bus.h> to <sys/bus.h> throughout.

Remove clause 3 and 4 from TNF licenses

Split device_t and softc for the NE2000 Ethernet chip and all its variants
and attachments. Use device_t accessors, correct types, and ANSIfy when
appropriate.

Use CFATTACH_DECL().

Declare all cfattach structures const.

add __KERNEL_RCSID as suggested by Luke Mewburn

- ANSIfy
- remove some trailing spaces/tabs
- minor style nits

Adjust the way that media is initialized on DP8390-compatible
chips. The dp8390_softc now has media_init and media_fini
function pointers that do the work.

The name is X-surf, not X-serv. I'll never learn this.
Thanks to Petri Koistinen for the correction.

sync with new bus.h

Rewrite of the Amiga bus_space machinery to prepare for the support of
the generic IDE driver and the PCMCIA slots.

Address range scaling is hidden by the bus_space functions. Correct the
definitions in case we ever do bus_space accounting on Amiga.

Another RTL8019 board: X-serve by Individual Computers Jens Schoenfeld.

New driver for the Ariadne II.
