c42073b2d4 Back out 1.143 and 1.144. They are no longer needed now that we start 
devd later in the boot process.  This should fix all the problems
people have had with those commits.  Diskless should be working again,
and those that mount /usr with nfs should be able to do that again too.

6d60ce9310 Start devd after the networking stuff, but before we mount the 
critical remote systems.  This lets us run commands from devd that
aren't on the / partition.  This also means we can remove some kludges
from the networking startup that I added a while ago that caused other
problems.

There's still a race in starting devd that needs to be fixed in devd
so that things present at boot will be configured by the time devd
does daemon().  That race will be fixed later.

5b3e8e8d83 Now that we don't have the NODEVFS case, we can just check to see if a 
device node exists directly to see if OLDCARD is compiled into the
kernel.  This eliminates the scary warning that people using NEWCARD
are seeing when they have pccard_enable=YES in their /etc/rc.conf
files.

f0e185d705 Implement a bio-taskqueue to reduce number of context switches in 
disk I/O processing.

        The intent is that the disk driver in its hardware interrupt
        routine will simply schedule the bio on the task queue with
        a routine to finish off whatever needs done.

        The g_up thread will then schedule this routine, the likely
        outcome of which is a biodone() which queues the bio on
        g_up's regular queue where it will be picked up and processed.

        Compared to the using the regular taskqueue, this saves one
        contextswitch.

Change our scheduling of the g_up and g_down queues to be water-tight,
at the cost of breaking the userland regression test-shims.

15c672a31d Make a mutex to stop the race coming into geom_disk's done routine. 
Cut up requests into smaller bits if they are longer than the drivers
disk->d_maxsize or dev->si_iosize_max.

Properly handle the race condition when using g_clone_bio() is used
without having the single-threadedness of g_down/g_up secure locking.

7f511526c2 Commit a nearly real man page describing the current state of devctl. 
More work likely needs to happen.  This describes things better than
the old "this man page intentionally left blank" style man page that
I'd committed previously.
