Put several fixes to ne(4) driver for better 8 bit mode support,
especially on RTL8019AS which is also used for non-ISA local bus of
embedded controllers and some m68k machines like atari and x68k.

* move RTL8019 probe and attach code from each bus attachment
to MI ne2000_detect() and ne2000_attach()
* change a method for backend and attachment to specify 8 bit mode
to use a new sc->sc_quirk member, instead of sc->sc_dmawidth
* handle more NE2000 8 bit mode specific settings, including
bus_space(9) access width and available size of buffer memory
* add a function to detect NE2000 8 bit mode
(disabled by default, but enalbed by options NE2000_DETECT_8BIT
to avoid possible regression on various ISA clones)
* fix ipkdb attachment accordingly (untested)

Tested on two NE2000 ISA variants (RTL8019AS and another clone named UL0001)
in both 8 bit and 16 bit mode on i386. "Looks good" from nonaka@.

Redefine bpf linkage through an always present op vector, i.e.
#if NBPFILTER is no longer required in the client. This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached. However, callers of bpf can
now be modularized.

Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff. ... and I'm not going to ponder the depths of unload
here.

Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

Correct return value of ne_*_match().
It's attach priority, not ne2000 model.

Delete 10 years old #if 0'd comments in intio.c, locore.s.
According to the old comment, the interrupt handler via intiotrap
should set his interrupt level again, but it's not right. And
don't set it again by interrupt hander.

Sync with other m68k ports.
- Remove PHYS_IODEV, PHYS_INTIODEV. These are real copy of INTIOBASE.
- Define IIOV() (and IIOP()) and use it, rather than INTIO_ADDR().

Change the signature of badaddr() and badbaddr() from taking a caddr_t
to taking a volatile void*. This gets rid of a number of casts to make
this compile under -Wcast-qual.
Add some volatiles and consts in other places to make this build under
-Wcast-qual.
Also rename a few variables to make this build under -Wshadow.
Also get rid of duplicated declarations of badaddr() and badbaddr()
in machdep.c, they're already there from <machine/cpu.h>.
