replaces it with two queues (input, output) where drivers (serial,
keyboard, video, usb) can attach.
The only things left with #ifdefs are initialization (at some point
the drivers must get a chance to register)

- no need for the client of libpayload to implement
usbdisk_{create,remove}, just because USB was compiled in.
- usb hub support compiles, and works for some trivial cases (no device
detach, trivial power management)
- usb keyboard support works in qemu, though there are reports that it
doesn't work on real hardware yet.
- usb keyboard is integrated in both libc-getchar() and curses, if
CONFIG_USB_HID is enabled

memalign implementation (eg. the one I sent yesterday).
Features:
- UHCI controller driver
- UHCI root hub driver
- USB MSC (Mass Storage Class) driver
- skeleton of a USB HID driver
(requires better interrupt transfer handling, which is TODO)
- skeleton of a USB hub driver
(needs several blank spots filled in, eg. power management.
Again: TODO)
OHCI and EHCI are not supported, though OHCI support should be rather
easy as the stack provides reasonable abstractions (or so I hope). EHCI
will probably be more complicated.
Isochronous transfers (eg. webcams, audio stuff, ...) are not supported.
They can be, but I doubt we'll have a reason for that in the boot
environment.
The MSC driver was tested against a couple of USB flash drives, and
should be reasonably tolerant by now. But I probably underestimate
the amount of bugs present in USB flash drives, so feedback is welcome.
