usb-ccid: add CCID bus
A CCID device is a smart card reader. It is a USB device, defined at [1].
This patch introduces the usb-ccid device that is a ccid bus. Next patches will
introduce two card types to use it, a passthru card and an emulated card.

Comment for "return consistent self-powered state":
the Configuration Descriptor bmAttributes claims we are self powered,
but we were returning not self powered to USB_REQ_GET_STATUS control message.
In practice, this message is not sent by a linux 2.6.35.10-74.fc14.x86_64
guest (not tested on other guests), unless you issue lsusb -v as root (for
example).
