In lookup() however it's the other way around as we need to supply the
dev_t for the vnode, so devfs still has a copy of it stashed away.
Sourcing it from the vnode in the vnops however is useful as it makes
a lot of the code almost the same as that in specfs.

Each devfs node has (and has had fro a while) a pointer directly to
the correct cdefsw entry so just use it instead of doing the lookup.
There are several other places in the kernel that still use the tables
however, so they can't go away yet..

There is only cdevsw (which should be renamed in a later edit to deventry
or something). cdevsw contains the union of what were in both bdevsw an
cdevsw entries. The bdevsw[] table stiff exists and is a second pointer
to the cdevsw entry of the device. it's major is in d_bmaj rather than
d_maj. some cleanup still to happen (e.g. dsopen now gets two pointers
to the same cdevsw struct instead of one to a bdevsw and one to a cdevsw).
rawread()/rawwrite() went away as part of this though it's not strictly
the same patch, just that it involves all the same lines in the drivers.
cdroms no longer have write() entries (they did have rawwrite (?)).
tapes no longer have support for bdev operations.

This code will be turned on with the TWO options
DEVFS and SLICE. (see LINT)
Two labels PRE_DEVFS_SLICE and POST_DEVFS_SLICE will deliniate these changes.
/dev will be automatically mounted by init (thanks phk)
on bootup. See /sys/dev/slice/slice.4 for more info.
All code should act the same without these options enabled.

This code does not support the following:
bad144 handling.
Persistance. (My head is still hurting from the last time we discussed this)
ATAPI flopies are not handled by the SLICE code yet.
When this code is running, all major numbers are arbitrary and COULD
be dynamically assigned. (this is not done, for POLA only)
Minor numbers for disk slices ARE arbitray and dynamically assigned.

also fixes a bug I've been chasing for a LONG TIME,
due to the fact that spec_bwrite is a NOP and I didn't realise it..
old symptom:
mount -t devfs devfs /mnt
mount /mnt/wd0e /mnt/mnt2
umount /mnt2 <process hangs>
there are some pretty large structural differences internal to devfs
but outwards it should look the same.
I have not yet tested extensively but will do so and fix 3 warnings tomorrow.

it 1138 times (:-() in casts and a few more times in declarations.
This change is null for the i386.
The type has to be `typedef int vop_t(void *)' and not `typedef
int vop_t()' because `gcc -Wstrict-prototypes' warns about the
latter. Since vnode op functions are called with args of different
(struct pointer) types, neither of these function types is any use
for type checking of the arg, so it would be preferable not to use
the complete function type, especially since using the complete
type requires adding 1138 casts to avoid compiler warnings and
another 40+ casts to reverse the function pointer conversions before
calling the functions.

it was referenced from.. stops a rather annoying panic, but
introduces a rather interesting but "I can live with it" bug
`ln a b ; mv a b; echo ?`
returns a rather than b..
I know why but I need to think of the 'correct' answer. at least this is 'safe'

added prototypes for every function and
put (void *) as the args to the vop array definitions.
can now compile with:
CWARNFLAGS?= -W -Wreturn-type -Wcomment -Wredundant-decls -Wimplicit \
-Wnested-externs -Wstrict-prototypes -Wmissing-prototypes \
-Winline -Wstrict-prototypes
and only get errors for files external to this module:
namely
./vnode_if.h
../../sys/vnode.h
../../sys/buf.h
../../miscfs/specfs/specdev.h

I did a cleanup on the code..
(why didn't I do that before I checked it in? I hear you ask..)
