xhci: drop buffering

This patch splits the xhci_xfer_data function into three.
The xhci_xfer_data function used to do does two things:

(1) copy transfer data between guest memory and a temporary buffer.
(2) report transfer results to the guest using events.

Now we three functions to handle this:

(1) xhci_xfer_map creates a scatter list for the transfer and
uses that (instead of the temporary buffer) to build a
USBPacket.
(2) xhci_xfer_unmap undoes the mapping.
(3) xhci_xfer_report sends out events.

The patch also fixes reporting of transaction errors which must be
reported unconditinally, not only in case the guest asks for it
using the ISP flag.

xhci: rip out background transfer code

original xhci code (the one which used libusb directly) used to use
'background transfers' for iso streams. In upstream qemu the iso
stream buffering is handled by usb-host & usb-redir, so we will
never ever need this. It has been left in as reference, but is dead
code anyway. Rip it out.

usb: unique packet ids

This patch adds IDs to usb packets. Those IDs are (a) supposed to be
unique for the lifecycle of a packet (from packet setup until the packet
is either completed or canceled) and (b) stable across migration.

uhci, ohci, ehci and xhci use the guest physical address of the transfer
descriptor for this.

musb needs a different approach because there is no transfer descriptor.
But musb also doesn't support pipelining, so we have never more than one
packet per endpoint in flight. So we go create an ID based on endpoint
and device address.
