Apache license is considered by some to be not compatible
with GPLv2+. Since QEMU as combined work is GPLv2-only,
these two files should be made compatible.

Canokey core currently using 16 bytes as maximum packet size for
control endpoint, but to run the device in high-speed a 64 bytes
maximum packet size is required according to USB 2.0 specification.
Since we don't acutally need to run the device in high-speed, simply
don't assign high member in USBDesc.
When canokey-qemu is used with xhci, xhci would drive canokey
in high speed mode, since the bcdUSB in canokey-core is 2.1,
yet canokey-core set bMaxPacketSize0 to be 16, this is out
of the spec as the spec said that ``The allowable maximum
control transfer data payload sizes...for high-speed devices,
it is 64 bytes''.
In this case, usb device validation in Windows 10 LTSC 2021
as the guest would fail. It would complain
USB\DEVICE_DESCRIPTOR_VALIDATION_FAILURE.
Note that bcdUSB only identifies the spec version the device
complies, but it has no indication of its speed. So it is
allowed for the device to run in FS but comply the 2.1 spec.
To solve the issue we decided to just drop the high
speed support. This only affects usb-ehci as usb-ehci would
complain speed mismatch when FS device is attached to a HS port.
That's why the .high member was initialized in the first place.
Meanwhile, xhci is not affected as it works well with FS device.
Since everyone is now using xhci, it does no harm to most users.

CCID could send zero-length packet (ZLP)
if we invoke two data_in, two packets would be concated
and we could not distinguish them.
The CANOKEY_EMU_EP_CTAPHID is imported from canokey-qemu.h

This commit added a new emulated device called CanoKey to QEMU.
CanoKey implements platform independent features in canokey-core
https://github.com/canokeys/canokey-core, and leaves the USB implementation
to the platform.
In this commit the USB part was implemented in QEMU using QEMU's USB APIs,
therefore the emulated CanoKey can communicate with the guest OS using USB.
