format_config: code preening.
vinum_scandisk: If we find a partition in the first pass over a drive,
note the fact so we don't grab the compatibility partition as well.

the aic7890/91/96/97 cards. This could cause the system to go into
a long retry/recovery loop during probe.
Fix the alignment argument to bus_dma_tag_create().
Don't set the CACHETHEN bit in dscommand0 for Ultra2 controllers
until we know more about its behavior. The description for this
bit makes it sound like it could cause problems with certain
PCI chipsets.
goes into initialized state, not 'up'. This makes it easier to ensure
consistency in multi-plex volumes.
update_plex_state: redo transitions from empty and initialized
subdisks to up or reviving, depending on the number of plexes.

Introduce BUF_STRATEGY(struct buf *, int flag) macro, and use it throughout.
please see comment in sys/conf.h about the flag argument.
Remove strategy argument from all the diskslice/label/bad144
implementations, it should be found from the dev_t.
Remove bogus and unused strategy1 routines.
Remove open/close arguments from dssize(). Pick them up from dev_t.
Remove unused and unfinished setgeom support from diskslice/label/bad144 code.
Don't return "can't do it" when the user requests a state change to
the current state. This previously caused silly messages like "Can't
start <foo>: invalid argument", when in fact <foo> was already
started.
set_plex_state: don't set state for non-existent plexes.
update_plex_status: as long as we have initializing subdisks, we're
initializing.
Move the declaration of freerq() to request.h.
logrq: add support for lock events.
vinumstart: solve a problem where removing a plex from an active
volume could cause attempts to access non-existent plexes.
launch_requests: don't set a request group active until we're sure we
can launch it. This caused some hangs under unusual
circumstances.
bre: don't set XFR_BAD_SUBDISK if we're not going to use it.
build_read_request: correct recovery, which caused some hangs under
(other) unusual circumstances.
build_rq_buffer: don't set bp->b_dev if we don't have a dev.
sdio: clean up, remove obsolete code.
deallocrqg: unlock any locks the rqg may have.
bre5:
Shorten some lines.

If we're reading from a short plex, return EOF indication.
Always lock the stripe before starting a transfer. Hopefully the
current version will solve some data integrity problems that have
been reported with degraded RAID-5 plexes.

Tidy other comments.
open_drive: don't call set_drive_state if we decide to take it down.
This could help avoid some race conditions with the daemon.
init_drive: don't set the drive down, we'll let close_locked_drive do
that.
close_locked_drive: set drive state to down without calling
set_drive_state. This could help avoid some race conditions with the
daemon.
driveio: remove the function, it wasn't being used.
get_volume_label: remove volume dependencies so that we can return a
label for plexes and subdisks as well. What a kludge.
Remove declarations for freerq and free_rqg.
Remove DEBUG_RESID code.
freerq: check whether the request is holding a lock, free if so.
free_rqg: remove. It wasn't being used any more.
Change the Debugger calls to panics.
checkdiskconfig(): remove. It didn't make any sense to complain about
kernel keywords in user config files; it just made it more difficult
to convert. Now we ignore kernel keywords if we're not in kernel
mode.
get_empty_sd: initialize sectors.
free_drive: don't close if we don't have a vp. Maybe this will help
fix the problem that peter had, but I wouldn't count on it.
config_plex: If the plex is RAID-5, give it a rangelock structure.
start_config: Reset current drive, plex and volume so that a new
'create' command doesn't get long-dead defaults.
struct rqelement, enum rqinfo_type, struct rqinfo, union rqinfou: add
lock requests.
Add declarations for freerq and unlockrange. Since they include
request structures, they can't go in vinumext.h
a module. Also modified the code to work on FreeBSD/alpha and added
device vr0 to the alpha GENERIC config.
While I was in the neighborhood, I noticed that I was still using
#define NFPX 1 in all of the Makefiles that I'd copied from the fxp
module. I don't really use #define Nfoo X so it didn't matter, but
I decided to customize this correctly anyway.
