d58a766556 DM USB: re-implement the data block process logic
In Windows OS, there are many non-data blocks (EVENT DATA) during the USB
data transfer process, which is very different from the Linux conterpart.
To support both OS, the data processing logic is changed with the help of
newly introduced enum usb_block_type.

patch is used to change them, no logic code are affected. The
changing included:

usb_data_xfer -> usb_xfer
usb_data_xfer_block -> usb_block

5a9627ced8 DM USB: xHCI: refine the emulation of Stop Endpoint Command
Old implementation does nothing when Stop Endpoint cmd is received,
it is not right. The new implementation will cancel all the libusb
requests in processing.

14bc961f03 DM USB: xHCI: remove old hub support code.
Previous design use bus and port(root hub port) for the identification
to the native USB device. It cannot work properly under the multi-hub
situation due to external USB hub is introduced.

This patch removes old hub implementation code, and subsequent patches
will be add support for mutiple hubs.

612037e138 DM USB: xHCI: enable Flat Mode Hub emulation support.
Flat Mode for hub emulation means DM emulates USB devices under hub but
hide hub itself. Under this design the Guest OS cannot see any emulated
hub. So in the perspective of Guest OS, all the emulated devices are
under root hub.

This patch is used to enable feature as mentioned above. And please NOTE,
it is the initial version of hub flat Mode hub emulation, there are one
limitation: only one physical hub is supported. If second physical hub is
connected, the connect and disconnect behavior in second hub may affect
the function of first emulated hub.

The USB HUB device model should be the final long term solution, but it is
very complex. Use flat mode HUB emulation as the short term solution first
to support some USB touch devices which integrated internal HUB.

2abec44e15 DM USB: introduce struct usb_native_devinfo
Current design cannot get physical USB device information without
the creation of pci_xhci_dev_emu. This brings some difficulties in
certain situations, hence struct usb_native_devinfo is introduced
to describe neccessary information to solve this trouble.
