usb-host: handle guest-issued clear halt

Most important here is to update our internal endpoint state so we know
the endpoint isn't in halted state any more. Without this usb-host
tries to clear halt again with the next data transfer submitted. Doing
this twice is (a) not correct and (b) confuses some usb devices,...

usb-redir: An interface count of 0 is a valid value

An interface-count of 0 happens when a device is in unconfigured state when
it gets redirected. So we should not use 0 to detect not having received
interface info from our peer.

usb-redir: Not finding an async urb id is not an error

We clear our pending async urb list on device disconnect and we may still
receive "packet complete" packets from our peer after this, which will then
refer to packet ids no longer in our list.

usb: add serial number generator

This patch adds a function which creates unique serial numbers for usb
devices and puts it into use. Windows guests tend to become unhappy if
they find two identical usb devices in the system. Effects range from
non-functional devices (with yellow exclamation mark in device manager)...

usb-uhci: update irq line on reset

uhci_reset() clears irq mask and irq status registers, but doesn't
update the irq line. Which may result in suspious IRQs after uhci
reset. Fix it.

usb-xhci: Use PCI DMA helper functions

Shortly before 1.0, we added helper functions / wrappers for doing PCI DMA
from individual devices. This makes what's going on clearer and means that
when we add IOMMU support somewhere in the future, only the general PCI...
