This patch adds zlib encoding support for VNC. It basically runs
the raw traffic through zlib, providing a pretty good compression
ratio.

Currently the send_framebuffer_update_raw and send_framebuffer_update_hextile
respectively send a send_framebuffer_update packet themselves. We need to reuse
send_framebuffer_update_raw for zlib encoding though, so let's move it out.

We will need to use buffer functions in code that will end up being
below the current buffer functions. In order to not introduce any
function stub defines, let's just move them up.

This patch enables the vnc server to understand fundamental tight extensions.
It changes from a "Hextile or not" scheme when sending framebuffer updates to
a "preferred encoding", namely the last one set.

While this is not perfect, as actually a list of "preferred encodings" should
be kept, it's good enough for now.

Now that we have nice defines for all sorts of constants, let's
use them!

This patch also takes the "feature variables", currently called has_*
into a single feature int. This way adding new features is a lot
easier and doesn't clutter the VncState struct.

The VNC protocol contains quite some constants, some of which are
currently hardcoded in the vnc.c code. This is not exactly pretty.

Let's move all those constants out to vnc.h, so they are clearly
separated. While at it, I also included other defines that will be
used later in this patch series.

Assume that in absolute mode the guest cursor always follows host cursor
and there's no need to move host cursor.  This avoids a strange feedback
loop.

The bdrv layer uses a signed offset. Furthermore, block-raw-posix
only seeks when that offset is positive. Passing a negative offset
to block-raw-posix can result in data being written at the current
seek cursor's position.

It may be possible to exploit this to seek to the end of the disk
and extend the virtual disk by writing data to a negative sector
offset.  After a reboot, this could lead to the guest having a
larger disk than it had before.

Close the hole by sanity checking the lba against the size of the
disk.

Load and save MTRR state together with machine state.

Add support for the MTRRcap MSR which is used by the latest Bochs BIOS
and some operating systems.

Fix a typo in ext2_feature_name.

With this patch, MTRR emulation should be good enough to not trigger any
sanity checks in well behaved BIOS/kernel code.
Some corner cases for BIOS/firmware usage remain to be implemented, but
that can be deferred to another patch.
Also, MTRR accesses on hardware not supporting MTRRs should cause #GP.
That can be enforced by another patch as well.

Currently when qemu_paio_read or qemu_paio_write return an error we call
qemu_aio_release without removing the request from the list.
I know that in the current implementation qemu_paio_write\read don't return
any error, but still the behavior is wrong, especially considering
that the implementation of these two functions is likely to change in is
the future.
This patch fixes the problem adding a raw_aio_remove function that
removes the callback from the queue and also calls qemu_aio_release.
raw_aio_remove is called by raw_aio_read, raw_aio_write and
raw_aio_cancel.

Paul Brook pointed out that the number of sectors reported
by the SCSI read capacity commands needs to be divided by
s->cluster_size, because bdrv_get_geometry reports the number
of 512 byte sectors, while emulated CDROMs report 2048 byte
sectors back to the guest.

This has no consequences for emulated hard disks, which use
a cluster size of 1.

Implement SCSI READ(16), WRITE(16) and SAI READ CAPACITY(16) commands,
so SCSI disks larger than 2TB can work with guests that support these
newer SCSI commands.

The cast to (uint64_t) is needed because otherwise gcc will use a
signed int, which gets sign extended into uint64_t lba, resulting
in bad block numbers for READ 10 and READ 16 with block numbers
larger than 2^31.

Sector numbers can overflow on a virtual scsi disk of over 1TB
in size.  Qemu's bdrv_read expects an int64_t, so fix the overflow
by going to that data type.

On large disks, we clip the capacity to 2TB instead of returning
"capacity modulo 2TB".

Turn sector_count into an unsigned to prevent a signed/unsigned
overflow with SCSI transfers larger than 2TB.  We're unlikely to
ever hit this bug, but fixing it is just one line.

It seems that the conversion of the kernel-delivered eflags state into
qemu's internal split representation was once needed in an older kvm
design (register read-back may have taken place from inside cpu_exec).
Today it is plain wrong and causes incorrect cpu state reporting (gdb,
monitor) and should also corrupt its saving (savevm, migration). Drop
the related lines.

The HPET emulation can disable the i8254 when the HPET is
in legacy mode, thus emulating the i8254's behavior.

But if it does, the i8254 doesn't have to be running, so
let's check to see if the timer works and not disable it
if it's not.

This fixes a segmentation fault when running Mac OS X as
