Replace device_init() with generalized type_init().
While at it, unify naming convention: type_init([$prefix_]register_types)
Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace.

Add a field to XHCITransfer to correctly keep track of NAK'ed usb
packets. Retry transfers when the endpoint is kicked again. Implement
wakeup_endpoint bus op so we can kick the endpoint when needed.
With this patch applied the emulated hid devices are working correctly
when hooked up to xhci. usb-tabled without polling, yay!

When some error happened we'll have to stop processing the endpoint.

With the separation of the device lookup (via usb_find_device) and
packet processing we can lookup device and endpoint before setting up
the usb packet. So we can initialize USBPacket->ep early and keep it
valid for the whole lifecycle of the USBPacket. Also the devaddr and
devep fields are not needed any more.

Switch over xHCI to use the new usb_find_device()
function for device lookup.

The USB subsystem pipes internal reset notifications through
usb_handle_packet() with a special magic PID. This indirection
is a pretty pointless excercise as it ends up being handled by
usb_generic_handle_packet anyway.
Replace the USB_MSG_RESET with a usb_device_reset() function
which can be called directly. Also rename the existing usb_reset()
function to usb_port_reset() to avoid confusion.

This was done in a mostly automated fashion. I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.
The first step was a sed-based addition of the parent type to the subclass
registration functions.
The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.
Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.
We are almost fully converted to QOM after this commit.

Based on the implementation from Hector Martin <hector@marcansoft.com>
Hectors's implementation completely sidestepped the qemu usb system and
used libusb directly for usb device pass through. So I've ripped out
the libusb bits (or left them in disabled, as reference for further
coding) and hooked up the qemu subsystem instead. That work is not
complete yet though, partly due to limitations of the qemu usb
subsystem. Nevertheless I think it is better to continue development
in-tree, especially as the qemu usb bits need a bunch of improvements
too for decent usb 3.0 support.
Current state:
- usb-storage emulation should work ok.
- Devices which need constant polling (HID emulation like usb-tablet)
are known to not work.
- ISO xfers are not implemented yet.
- superspeed ports are not implemented yet.
- usb pass-through is completely untested so far.
