- 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.

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.

This patch fixes both issues, and as a side effect, removes all
integer division from the hypervisor side of the trace mechanism.

xentrace: Fix bug in logic for bytes_to_wrap in trace buffer.
Admittedly, the bug could only be manifest with much larger trace
records than are currently allowed (or equivalently, much smaller
trace buffers), but the old code was harder to read, and thus hid the
logic bug well, too.

When I rebooted a domain by xm reboot command with wait option,

The cause why the message was shown is the domain is destroyed
temporarily by processing of xm reboot command. The domain
information is not gotten from Xend by server.xend.domains()
function till recreating the domain is completed.

ioemu: avoid name clashes due to LIST_* macros
Here is what I wrote in my submission to qemu upstream:
qemu's audio subdirectory contains a copy of BSD's sys-queue.h, which
defines a bunch of LIST_ macros. This makes it difficult to build a
program made partly out of qemu and partly out of the Linux
kernel[1], since Linux has a different set of LIST_ macros. It might
also cause trouble when mixing with BSD-derived code.
Under the circumstances it's probably best to rename the versions in
qemu. The attached patch does this.
[1] You might well ask why anyone would want to do this. In Xen we
are moving our emulation of IO devices from processes which run on
the host into a dedicated VM (one per actual VM) which we call a
`stub domain'. This dedicated VM runs a very cut-down `operating
system' which uses some code from Linux.

[IA64] Fix domain refernece counting
Fix the domain refernece counting caused by allocated pages from domheap for
shared page and hyperregister page. Calling share_xen_page_with_guest() with
domain heap page is wrong so that it increments domian->xenpages which is
never decremented. Thus the domian refcount doesn't decrease to 0 so that
destroy_domain() is never called. This patch make the allocation done from
xenheap again.
The other way to fix it is to work around domain->xenheap and the page
refrence count somehow, but it would be very ugly. The right way to do so
is to enhance the xen page allocator to be aware of this kind of page in
addition to xenheap and domheap. But we don't want to touch the common code.
And given that the limitation on xenheap of xen/ia64 is much relaxed,
probably it isn't necessary to be so nervouse not to allocate those pages
from xenheap. If it happend to be necessary to allocate those pages from
domheap, we could address it at that time. For now just allocate them from
xenheap.
