This patch adds support for the ExtendedKeyEvent client message.  This message
allows a client to send raw scan codes directly to the server.  If the client
and server are using the same keymap, then it's unnecessary to use the '-k'
option with QEMU when this extension is supported.

This is extension is currently only implemented by gtk-vnc based clients
(gvncviewer, virt-manager, vinagre, etc.).

While trying to make VX-3000 camera work on XP under KVM I realized that
we do not necessarily have to find original TD address. All we care about
is the token which identifies the transfer rather well (direction, endpoint,
size, etc).
This is especially important for the isochronous transfers because otherwise
they are being canceled left and right and we do not make much progress.

With this patch all devices that used bulk transfers that I've tried so
far continue to work just as well. And now my USB web cammera (isoc transfers)
is working well tool. It's not as smooth as native Windows but it's pretty
darn smooth.

The cool thing is that new USB code (both usb-uhci and usb-linux) is totaly
generic and does not need any special logic for ISOC.

When a TLB miss occurs while pre-decrement store instruction such as
"mov.l Rm, @-Rn" is executed, re-execution of such instruction cause
status confusion. Because pre Rn decrement is executed before TLB miss,
re-execution decrements Rn again.
In other words, in a translated instruction array, register status
should not modified before memory access instruction.

Some bugs on SH4 MMU are fixed.

- When a TLB entry is overwritten or invalidated, tlb_flush_page() should be
  invoked to invalidate old entry.
- When a ASID is changed, tlb_flush() should be invoke to invalidate entries
  which have old ASID.
- The check for shared bit in TLB entry causes multiple TLB hit exception.
  As SH3's MMU, shared bit is ignored.
- ASID is used when MMUCR's SV bit or SR's MD bit is zero.
  No need to check both bits are zero.

SH4 MMU's memory mapped TLB feature is implemented.
SH-Linux seems to write to memory mapped TLB to invalidate a TLB entry,
but does not to read it. So only memory write feature is implemented.

Two bugs about delay slot handlings are fixed.

- After an exception occurred in delay slot, the branch instruction
  before delay slot should be executed again. To judge such re-execution
  is necessery or not, delay slot status is kept in SH4 CPU data structure.
- When a branch instruction is placed at the end of memory segment,
  the delay slot is placed at the start of next memory segment.
  It means delay slot comes to the start of a translation block.
  In such occasion, DELAY_SLOT_CLAREME flag is used to transmit status
  between translation blocks. When an exception occurs on this kind of
  delay slot, DELAY_SLOT_CLEARME flag cause a status confusion in exception
  handling. DELAY_SLOT_CLEARME flag should be cleared on exceptions.

And some items are added to CPU status dump.

The direction bit in the control register should not be directly

set using PPWCONTROL. The kernel gives the following debug message.

    parport0 (ppdev0): use data_reverse for this!

More over setting the data pins to forward mode does not work,
perhaps a bug in the Linux PP driver. The right way to do this is
to use PPDATADIR to set the direction. The patch checks if the
user is toggling the direction bit, and invokes PPDATADIR to
do the job.

This patch makes qemu handle signals better.  It sets the request_shutdown
flag, making the main_loop exit and qemu taking the usual exit route, with
atexit handlers being called and so on, instead of qemu just being killed
by the signal.

To avoid calling vm_start() from the signal handler main_loop() got an
additional check so qemu_system_shutdown_request() works even when the
vm is in stopped state.

For some reason we were not registering save/load-vm handler for piix3
flavor of UHCI and hence save/load was broken.

Async transactions need to be canceled when we save the VM because there
is no way we can save/restore all that state. Since we do not mess the
original TD/QH the driver will simply resubmit the transfers.

This is a follow up to the async UHCI patch. Both BULK and ISOC transactions
are now fully asynchrounous. I left CONTROL synchronous for now, ideally
we want it to be async too and it should not be that hard to do now.

This patch obviously requires UHCI patch. The combo has been tested with
various devices. See the UHCI patch description for list of the devices.
Most of the testing was done with the KVM flavor of QEMU.
