Based on the ehci bits collected @ git://git.kiszka.org/qemu.git ehci

EHCI has a long out-of-tree history. Project was started by Mark
Burkley, with contributions by Niels de Vos. David S. Ahern continued...

usb: add usb_handle_packet

Add a usb_handle_packet function, put it into use everywhere.
Right now it just calls dev->info->handle_packet(), that will
change in future patches though.

usb: move cancel callback to USBDeviceInfo

Remove the cancel callback from the USBPacket struct, move it over
to USBDeviceInfo. Zap usb_defer_packet() which is obsolete now.

usb: add support for "grouped" interfaces and the Interface Association Descriptor

This is used for some devices that have multiple interfaces that form a logic
device. An example is Video Class, which has a Control interface and a
Streaming interface. There can be additional interfaces on the same (physical)...

usb: Pass the packet to the device's handle_control callback

This allows using the generic usb_generic_handle_packet function from
device code which does ASYNC control requests (such as the linux host
pass through code).

usb-linux: use usb_generic_handle_packet()

Make the linux usb host passthrough code use the usb_generic_handle_packet()
function, rather then the curent DYI code. This removes 200 lines of almost
identical code.

usb-storage: don't call usb_packet_complete twice

usb_msd_copy_data() may cause a recursive call to
usb_msd_command_complete() which in turn may complete
the packet, setting s->packet to NULL in case it does.
Recheck s->packet before calling usb_packet_complete()...
