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.

I or someone else interested with smp will eventually clear this up.
