ioemu: VNC updates should be sent only when requested.
Reading qemu code I realized that the qemu vnc server sometimes sends
framebuffer updates even if the client didn't request any. This is not
consistent with the RFB protocol spec and can break some clients.
This patch strictly enforces compliance with the RFB protocol making
sure framebuffer updates are sent only if the client requested one.
Doing so is more difficult than it seems because some framebuffer
pseudo-encoding updates cannot be discarded but must be sent anyway:
for example desktop resize and pixel format change messages. To solve
the problem I wrote a queue that stores those messages and sends them
as soon as the client asks for an update. Since 90% of the times the
queue is used to store only few elements, the queue allocates 10
elements at the beginning and every time it runs out of elements
allocates other 10 elements. This is should drastically limit the
number of malloc and free needed to maintain the queue. I did some
stress tests in the last couple of days and seems to work well.

Provide fast write emulation path to release shadow lock.
Basically we can consider shadow fault logic into two parts,
with 1st part to cover logistic work like validating guest
page table or fix shadow table, and the 2nd part for write
emulation.
However there's one scenario we can optimize to skip the
1st part. For previous successfully emulated virtual frame,
it's very likely approaching at write emulation logic again
if next adjacent shadow fault is hitting same virtual frame.
It's wasteful to re-walk 1st part which is already covered
by last shadow fault. In this case, actually we can jump to
emulation code early, without any lock acquisition until
final shadow validation for write emulation. By perfc counts
on 64bit SMP HVM guest, 89% of total shadow write emulation
are observed falling into this fast path when doing kernel
build in guest.

3. On guest linux, execute insmod:

Add stubdomain support. See stubdom/README for usage details.
- Move PAGE_SIZE and STACK_SIZE into __PAGE_SIZE and __STACK_SIZE in
arch_limits.h so as to permit getting them from there without
pulling all the internal Mini-OS defines.
- Setup a xen-elf cross-compilation environment in stubdom/cross-root
- Add a POSIX layer on top of Mini-OS by linking against the newlib C
library and lwIP, and implementing the Unixish part in mini-os/lib/sys.c
- Cross-compile zlib and libpci too.
- Add an xs.h-compatible layer on top of Mini-OS' xenbus.
- Cross-compile libxc with an additional xc_minios.c and a few things
disabled.
- Cross-compile ioemu with an additional block-vbd, but without sound,
tpm and other details. A few hacks are needed:
- Align ide and scsi buffers at least on sector size to permit
direct transmission to the block backend. While we are at it, just
page-align it to possibly save a segment. Also, limit the scsi
buffer size because of limitations of the block paravirtualization
protocol.
- Allocate big tables dynamically rather that letting them go to
bss: when Mini-OS gets installed in memory, bss is not lazily
allocated, and doing so during Mini-OS is unnecessarily trick while
we can simply use malloc.
- Had to change the Mini-OS compilation somehow, so as to export
Mini-OS compilation flags to the Makefiles of libxc and ioemu.

ioemu: Dynamic VNC colour depth.
The qemu vnc server changes its internal colour depth based on the
client request. This way just one colour conversion is done: the one
in vga_template.h, from the guest colour depth and the vnc server
internal colour depth.
This patch is meant to remove this colour conversion to improve
performances. It accomplishes the goal making the qemu internal colour
depth always the same as the guest colour depth.
The basic idea is that the vnc client is the one that should do the
colour conversion, if necessary. In general it should accept the pixel
format suggested by the server during the initial negotiation. This
behaviour can be set in most vnc clients (vncviewer included).
If the guest changes colour depth, the qemu vnc server changes colour
depth too and notifies the client. The problem is that the vnc
protocol doesn't provide a message from the server to the client to
ask for a colour depth change. So what I am doing is either:
1) quietly starting to do the conversion on vnc server (not gaining
any performance here);
2) closing the vnc connection with the client, so the client can
reconnect and choose the new pixel format.
By default I am doing 1), however the second choice can be enabled
passing the -vnc-switch-bpp command line option.
In order to do the colour conversion on the vnc server I had to
improve the colour conversion code already in place because it only
supported conversions from 32 bpp. The patch adds colour conversion
code that support conversions from any resolution to any resolution.
A last note: to get most out of this patch it is best to set Windows
to 16 bit colour depth, because the 24 bit mode is 24 bit depth and 24
bpp, meaning no alpha channel. The vnc protocol doesn't support 24
bpp, only 32 bpp, so this conversion is unavoidable.
