This was pretty harmless as netmasks on a POINTOPOINT
interface are pretty much ignored, but it looked funny.
Mention the configured netmask in ``show ipcp''.
Describe in more detail what a proxy arp entry is.
Added "options ATA_STATIC_ID" that wires ATA disks like the old wd driver.
Fixed problems:
Dont use more sectors/intr than the drive supports.
Fix announce of > 8.4G disks.
Dont call ad_interrupt/ad_transfer when no disks config'd.
Use the right page# for CDR write mode params.
Fix breakage when no PCI support in kernel.
Implement DEVFS stuff.
General code clenaup.
Higher numbers led to smaller quanta.
In discussion with BDE, change this parameter to be in uSecs
to make it machine independent,
and limit it to non zero multiples of 'tick' (rounding down).
Also make the variabel globally available so that the present function that
returns its value (used for posix scheduling I believe) can go away.

the read lock around the subyte operations in mincore. After the lock is
reacquired, use the map's timestamp to determine if we need to restart
the scan.
This produced races resulting in panics and filesystem corruptions
under some circumstances.

For whatever reason, the kernel seems to have generated SIGIOs
previously without an initial fcntl(...,F_SETOWN), but does no longer.
This caused window(1) to wait indefinitely for input.
Also, undo rev 1.3 of wwspawn.c, it was not well-thought, and
apparently not even tested at all. The blindly (even in a nonsensical
place like the comment on top of the function) applied replacement of
vfork() by fork() totally ignored that window(1) *does* abuse the
feature of vfork() where a modification of the parent's address space
is possible (in this case, to notify the parent of an erred exec*).
Also, with vfork(), it is guaranteed that the parent is only woken up
after the exec*() happened, where the replacement by fork() made the
parent to almost always become runnable again before the child, in
which case the parent simply told `subprocess died'. Unfortunately,
working around _this_ seems to be a lot more of redesign work compared
to little gained value, so i think relying on the specifics of vfork()
is the simpler way.

Describe /dev/vinum/control*
Describe drive "referenced" state.
Remove warning about kldunload; it seems to work now.
Still more descriptions of how to debug things.
Wait4 zombies.
make_devices: Don't try if the /dev directory is mounted read-only.
Create daemon superdevice /dev/vinum/controld.
Format a couple of multiline comments conformant with style(9).
for us.
Rebuild the (almost empty) /dev/vinum directory.
vinum_start: remove superflous "read" parameter when starting with no
parameters.
vinum_stop: without an argument, stop Vinum and remove the kld if
it's idle.
vinum_saveconfig: New command to save configuration.
Change VINUM_SAVECONFIG: it now requires a parameter. 0 means
"configuration updates are finished, please save", and 1 means "please
just save the config". This second meaning is invoked by the new
"saveconfig" command to vinum(8).
