6dc06f08b3 scsi: add support for unit attention conditions
Unit attention conditions override any sense data the device already
has.  Their signaling and clearing is handled entirely by the SCSIBus
code, and they are completely transparent to the SCSIDevices.

c39ce112b6 scsi: pass cdb already to scsi_req_new
Right now the CDB is not passed to the SCSIBus until scsi_req_enqueue.
Passing it to scsi_req_new will let scsi_req_new dispatch common requests
through different reqops.

Moving the memcpy to scsi_req_new is a hack that will go away as
soon as scsi_req_new will also take care of the parsing.

b45ef674f4 scsi: move sense handling to generic code
With this patch, sense data is stored in the generic data structures
for SCSI devices and requests.  The SCSI layer takes care of storing
sense data in the SCSIDevice for the subsequent REQUEST SENSE command.

At the same time, get_sense is removed and scsi_req_get_sense can use
an entirely generic implementation.

682a9b213c scsi: pass status when completing
A small improvement in the SCSI request API.  Pass the status
at the time the request is completed, so that we can assert that
no request is completed twice.  This would have detected the
problem fixed in the previous patch.

05751d3ff7 vscsi: always use get_sense
vscsi supports autosensing by providing sense data directly in the
response.  When get_sense was added, the older state machine approach
that sent REQUEST SENSE commands separately was left in place.  Remove
it, all existing SCSIDevices do support autosensing and the next patches
will make the support come for free from the SCSIBus.

e44089c79d scsi-disk: no need to call scsi_req_data on a short read
In fact, if the HBA's transfer_data callback goes on with scsi_req_continue
the request will be completed successfully instead of showing a failure.
It can even cause a segmentation fault.

An easy way to trigger it is "eject -f cd" during installation (during media
test if the installer does something like that).

4333979e3d pc: make vgabios exit port more useful
We've always listened on port 501 for vgabios panic messages.  In the entire
time I've worked on QEMU, I've never actually seen a vgabios panic message :-)

If we change the semantics of this port a little bit, it makes it possible to
use it for more interesting use-cases.  I chose this approach instead of adding
a new I/O port because it avoids having a guest visible change.

This change allows single-byte access to port 501 and also uses the value
written to construct an exit code.

21635e121a usb/hid: add hid_pointer_activate, use it
HID reorganziation broke the usb tablet in windows xp.  The reason is
that xp activates idle before it starts polling, which creates a
chicken-and-egg issue:  We don't call hid_pointer_poll because there are
no pending events.  We don't get any events because the activation code
in hid_pointer_poll is never executed and thus all pointer events are
routed to the PS/2 mouse by qemu.

Fix this by creating a hid_pointer_activate function and call it from
usb-hid when the guest sets the idle state.
