replaces an older attempt to silence vinum(8) when started in
single-user mode.
Add entries for vinum_raid[45].
Replace the preprocessor variable name CDEV_MAJOR with
VINUM_CDEV_MAJOR.

vinum_lvi: Change line spacing. This is still not right.
Change checks for striped or RAID-5 plexes to a macro 'isstriped',
which now also includes RAID-4.
Change checks for RAID-5 plexes to a macro 'isparity', which now also

vinum_lsi: If the subdisk is initializing or reviving, don't wait a
whole second to check whether it's advancing; wait in increments of 50
ms up to 1 second. This makes for a barely perceptible delay.

enabled and print a warning message in varous places if they are not.
Fix typos in comments.
Change some indents to approach style(9).
initvol: If init fails, place the subdisks in a "down" state.
vinum_start(): If we're starting a plex, try doing it directly. It's
possible that the state of the plex differs from that of the subdisks,
for example if somebody has used 'setupstate'.
New functions vinum_raid4 and vinum_raid5 to create RAID-4 and RAID-5
volumes, analagous to vinum_mirror and vinum_stripe.
vinum_checkparity: Don't try to check the parity of a non-parity plex,
print a rude remark instead.

VINUM_BDEV_MAJOR and VINUM_CDEV_MAJOR respectively.
Set DRIVE_MAXACTIVE and VINUM_MAXACTIVE to 30000, effectively
disabling the request limitation code. This code was added as an
attempt to escape from a bug which seems to have gone away, and it's
very likely I'll remove the code Real Soon Now, but I don't want to do
it just yet.
struct drive: Remove references to vnode pointers, including debug
output. Vinum now talks directly to the device driver. Instead, add
a dev_t.
enum plexorg: Add an instance for RAID-4.
Change checks for striped or RAID-5 plexes to a macro 'isstriped',
which now also includes RAID-4.

comes up.

start_object: Return a sensible error message when trying to revive a
subdisk whose drive is down. Previously it returned EBUSY.

vn_open. This is necessary in order to be able to open drives before
the root file system is mounted. This also involves restructuring the
drive struct, which no longer contains a vnode pointer. Instead,
open_drive sets an open flag. It's a horrible kludge, and I'll gladly
borrow a Danish axe and hack it in little pieces when devfs comes.
read_drive, write_drive, drive_io_done: Replace with driveio. The
function names are now macros.
driveio: Fix horrible, embarrassing breakage which was the reason why
read_drive and write_drive existed in the first place.

to RAID-5. peter claims that it might be faster for sequential
reading, since the drive caches don't trip over the parity blocks. I
have seen no evidence to support this, but it's a trivial change.

atoi(): Remove, nobody was talking to it.
give_sd_to_drive: If no space is available, make the subdisk down,
don't delete it.
Change the manner in which the subdisk count was maintained to avoid
cases where the count was not adjusted correctly.
config_drive: Check if we have subdisks referencing us, and add them
if so. This fixes problems which arose when a drive is replaced in a
running system.
config_sd: Add support for a keyword 'partition', whose meaning will
be revealed in the fullness of time.
Cosmetic: Shorten some console messages.

Direct blocks: 8094568 0 0 0 0 0 0 0 0 0 0 0

The problem turns out to be a program logic error in fsck. It stores
directory inodes internally in hash lists, using the number of
directories to form the hash key:
inpp = &inphead[inumber % numdirs];
Elsewhere, however, it increments numdirs when it finds unattached
directories. I've made the following fix, which solved the problem in
the case in hand.
