Xen won't be enabled if there is no backend support available for the
host. And that also means the map cache will work. So drop the separate
config switch and move the required stubs over to xen-stub.c.

This bug was introduced in 94d3f98a3f:
scsi_cancel_io was checking if some request was pending before trying
to cancel it, while scsi_req_cancel always cancels the request.
This may lead to a crash of Qemu due to dereferencing a NULL pointer,
as exhibited by NetBSD 5.1 installer on MIPS Magnum emulation.

To use as a companion controller, use pci-ohci as device and set the
masterbus and num-ports properties, ie:
-device usb-ehci,addr=0b.1,multifunction=on,id=ehci0
-device pci-ohci,addr=0b.0,multifunction=on,masterbus=ehci0.0,num-ports=4

with the "usb-ehci: cleanup port reset handling" patch in place no callers
are calling usb_attach(port, NULL) for a port where port->dev is NULL.
Doing that makes no sense as that causes the port detach op to get called
for a port with nothing attached. Add an assert that port->dev != NULL when
dev == NULL, and remove the check for not having a port->dev in the dev == NULL
case.

Doing a usb_attach when dev is NULL will just result in the
port detach op getting called even though nothing was connected in
the first place.

Note this fixes 2 things in one go, first of all the device_destroy bus
op should be a device_detach bus op, as pending async packets from the
device should be cancelled on detach not on destroy.
Secondly having this as a bus op won't work with companion controllers, since
then there will be 1 bus driven by the ehci controller and thus 1 set of bus
ops, but the device being detached may be downstream of a handed over port.
Making the detach of a downstream device a port op allows the ehci controller
to forward this to the companion controller port for handed over ports.

This makes them consistent with the attach and detach ops, and in general
it makes sense to make portops take a port as argument. This also makes
adding support for a companion controller easier / cleaner.

Just in case there's still a way how a guest can read out buffers when it's not
supposed to, let's zero the buffers during initialisation so that we don't leak

This fixes https://bugs.launchpad.net/qemu/+bug/786209:
When the DRQ_STAT bit is set, the IDE core permits both data reads
and data writes, regardless of whether the current transfer was
initiated as a read or write.
This potentially leaks uninitialized host memory into the guest,
if, before doing anything else to an IDE device, the guest begins a
write transaction (e.g. WIN_WRITE), but then *reads* from the IO
port instead of writing to it.
