Convert the PL061 to VMState. We choose to widen the struct members
to uint32_t rather than the other two options of breaking migration
compatibility or using vmstate hacks to read/write a 32 bit value
into an 8 bit struct field.

The Versatile Express, Realview EB, PBX A9 and PB A8 boards all
use a PL111 for their graphics, not a PL110. Now we model the
PL111, use it on these board models.
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
On the Versatile PB, PL110 graphics adaptor only natively supports
5551 pixel format; an external mux swaps bits around to allow
RGB565 and BGR565, under the control of bits [1:0] in the SYS_CLCD
system register.
Implement these SYS_CLCD register bits, and use a gpio line to
feed them out of the system register model, across the versatilepb
board and into the pl110 so we can select the right format.
This is necessary as recent Linux versatile kernels default to
programming the CLCD and mux for 16 bit BGR rather than 16 bit RGB.

Model the PL111 CLCD controller. This is a minor variation
on the PL110; the major programmer visible differences are
support for hardware cursor (unimplemented) and two new
pixel formats.
Since syborg_fb.c borrows the pl11x pixel drawing routines,
we also update it to cope with the new slightly larger array
of function pointers.

Other scsi_target_reqops commands were careful about not using r->cmd.xfer
directly, and instead always cap it to a fixed length. This was not done
for REQUEST SENSE, and this patch fixes it.

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.

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

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.

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).

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.

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.
