and partially r188903. Revert breaks new drives detection on reinit to the
state as it was before me, but fixes series of new bugs reported by some
people.
Unconditional queueing of ata_completed() calls can lead to deadlock if
due to timeout ata_reinit() was called at the same thread by previous
ata_completed(). Calling of ata_identify() on ata_reinit() in current
implementation opens numerous races and deadlocks.
Problems I was touching here are still exist and should be addresed, but
probably in different way.
When copying big structures, LLVM generates calls to memmove(), because
it may not be able to figure out whether structures overlap. This caused
linker errors to occur. memmove() is now implemented using bcopy().
Ideally it would be the other way around, but that can be solved in the
future. On ARM we don't do add anything, because it already has
memmove().

Increasing WARNS seems to have broken compilation of this utility.
Instead of lowering WARNS, just fix to code to compile properly.

Add softc memory deallocation on device destruction.
On FreeBSD, this is the default behaviour. According to the spec, we may
give this flag a value of zero, but I'd rather not do this. If we define
it to a non-zero value, we can always change default behaviour without
changing the ABI. This is very unlikely to happen, though.

at irq install/uninstall time, but when we vt switch, we uninstall the
irq handler. When the irq handler is reinstalled, the modeset ioctl
happens first. The modeset ioctl is supposed to tell us that we can
disable vblank interrupts if there are no active consumers. This will
fail after a vt switch until another modeset ioctl is called via dpms
or xrandr. Leading to cases where either interrupts are on and can't
be disabled, or worse, no interrupts at all.

Not sure that's a good idea, as we were moving away from it, but this
fixes the build in the mean time so we can have that discussion.
- Fix the copy, we can't do a blind copy but must transfer
the data from the old to the new.
- Fix the ACK processing so we properly stop retransmitting
the thing.
- Fix it so if we get a retran we will properly reply with
the saved response without doing anything.

Either use parameters provided by user or make them up.
The code for faking CHS params is borrowed from disklabel code.
The logic for using user-provided and auto-guessed parameters is not
perfect, so to speak.

The /dev entries are layed out as follows,
/dev/usbctl = master device
/dev/usb/0.1.0.5 = usb device, (<bus>.<dev>.<iface>.<endpoint>)
/dev/ugen0.1 -> usb/0.1.0.0 = ugen link to ctrl endpoint

net/route.h.
Remove the hidden include of opt_route.h and net/route.h from net/vnet.h.
We need to make sure that both opt_route.h and net/route.h are included
before net/vnet.h because of the way MRT figures out the number of FIBs
from the kernel option. If we do not, we end up with the default number
of 1 when including net/vnet.h and array sizes are wrong.
This does not change the list of files which depend on opt_route.h
but we can identify them now more easily.
printf() and vprintf() are exactly the same, except the way arguments
are passed. Just like we see in other pieces of code (i.e. libc's
printf()), implement printf() using vprintf().
