Closes PR # kern/1065.
While i was at it, also reject IO requests that are not an integer
multiple of the device blocksize.

workings of #error in particular. He also broke the 2.2 build with this
change, leading me to wonder whether or not the changes were ever even
tested. Folks, I'm happy to see people work directly on 2.2 like
this and will continue to encourage Nate to make direct commits, but
please TEST before committing! I think that's a more than reasonable
prerequisite, and this code could never have worked at all, leading me to
believe that Nate skipped this most basic of steps.
Don't allow people to use the 'dedicated' drivers at the same time as
the generic support code, as it can cause all sorts of problems
including kernel crashes.
[ definite 2.2 material ]
after the first found, if multiple LUNs are tried.
Change probe message to just the SCSI chip id,
similar to what the NCR driver prints.
Change the driver name to "amd" in all places.
Thanks to Nick Sayer <nsayer@quack.kfu.com> for
doing some debugging, for sending a boot message
log that shows the driver is functional, and for
pointing out there still were places that needed
the driver name to be corrected.
Broke locking on named pipes in the same way as locking on non-vnodes
(wrong errno). This will be fixed later.
The fix involves negative logic. Named pipes are now distinguished from
other types of files with vnodes, and there is additional code to handle
vnodes and named pipes in the same way only where that makes sense (not
for lseek, locking or TIOCSCTTY).
fcntl() and EOPNOTSUPP for flock(). POSIX specifies the weaker EINVAL
errno and the man page agrees.
Not fixed:
deadfs: always returns wrong EBADF
devfs, msdosfs: always return sometimes-wrong EINVAL
cd9660, fdesc, kernfs, portal: always return sometimes-wrong EOPNOTSUPP
procfs: always returns wrong EIO
mfs: panic?!
nfs: fudged
NetBSD uses a generic file system genfs to do return the sometimes-wrong
EOPNOTSUPP more consistently :-)(.

- C++ should be supported for application functions (use __BEGIN_DECLS,
etc.).
- prototypes should be sorted.
- comments on #endif's should spell identifiers the same as the code.
- comments on #endif's should have the same sense as the code (use `!'
to match ifndef, etc.).

(Note that this file has no copyright header; one should probably
be added.)
This makes unexpected faults (in an interrupt handler) more likely
to crash properly. It could be done even better (more robustly and
more efficiently) using lazy fault handling.
