HEADS UP: USB4BSD is the default USB stack now

I have switched over our USB stack to USB4BSD and there are a few things
Regarding driver support, controllers (including XHCI), keyboard, mouse
and mass storage are working well enough, as are axe(4), rum(4), run(4)
and urtwn(4). I assume John will enable libusb dependent dports in the
near future too.
Regarding what works _not_ :)... Here's a list of things known to have no
support or issues still:
Network: aue(4), cue(4), kue(4), lgue(4), rue(4)
Serial: Serial is being worked on right now, it is still unstable.
Audio: USB audio needs an upgrade of the audio stack, of which a work
in progress exists, but nothing in the tree yet.
Bluetooth: This, as far as I can tell, would benefit from switching over
to the newer netgraph stack we have (but it is not default).
Regarding scanner support and some more obscure devices like F/M radio
etc., I don't know if dedicated drivers are still needed with the new
stack or if it is handled from userland via ugen(4).
In any case, to move back to old stack, you need to add "WANT_OLDUSB=yes"
to /etc/make.conf and put "device oldusb" in your kernel config and
rebuild/install world and kernel (don't forget 'make upgrade' as it does
module cleanup between the two stacks).
Please also note that those who have added "device usb4bsd" to their
kernel configurations for testing purposes in the past will need to
replace it with "device usb" again. WANT_USB4BSD can be removed from
/etc/make.conf too (it's a no-op now, so nothing will break if it is left).
