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.

A small improvement in the SCSI request API. Pass the status

no request is completed twice. This would have detected the

vscsi: always use get_sense
vscsi supports autosensing by providing sense data directly in the

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.

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).

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.

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.
The Bare ETRAX FS board was a fictive machine that I used when
developing the CRIS system emulation. Since we support the
real AXIS-dev88 developer boards, there is no reason to
keep the fictive one around.
This commit also removes the double registration of the axis-dev88
board.
