Message:

Merge initial USB unplug support.

Support device_remove and device_gone in libusbdev.
usbhub and uhcirh try to unbind and destroy functions of attached devices.
add unplug support for usbhub driver (only works on empty hubs as there is no support in other drivers).

Drivers to go:

usbmid
usbflbk
usbhid
usbmast
usbmouse

Tested on:

qemu UHCI and emulated hub,
ICH8 hw and Alcor Micro Corp. USB Hub
