Per Intel 82540EM Software Developer's Manual pp. 211, the mmio size
is 0x20000, or address overlapping occurs and causes the second card
to fail, which happened to me earlier.

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.

This is a direct port of the e1000 driver currently in Qemu CVS with
extremely minimal changes. This is useful for Xen as new OSes may not
support the old 100Mbps NICs we currently support (especially on
non-x86). Drivers for e1000 should be more readily available.

I am adding some functions for external tools to call the vTPM scripts.
It also contains a fix for the functions that previously used to be

No need to generate the correct number dynamically since
present/not-present can be determined from the MADT. What *is*
required is that we have a Processor Object for every present
processor. We statically declare 16 Objects, which should be plenty
for now.

This patch adds support for the qcow2 image format to blktap. It
consists mostly of qemu code, adapted to the blktap interfaces.
Snapshots and compressed images are supported.
The qcow2 driver may be used by either specifying tap:qcow2 or by
using tap:qcow which will detect that you have a version 2 image and
will call the qcow2 driver.

Previously a newline was forced after every call to
write_with_timestamp. This could result in some ugly logs when a
single console line stretched over multiple calls. This change carries
some extra state to determine if we ended the last call to
write_with_timestamp on a newline, and prints the timestamp as
appropriate.
This also fixes a bug where logging hv messages was dependent on the
guest timestamp flag.

Now that the qemu WMVi patch is applied we can take full advantage of
it sharing the video buffer between the vga driver and the qemu vnc
server. This saves a lot of memcpy. It's worth mentioning again that
when the guest colour depth is 24 bit we cannot share the buffer
because 24 bpp is not supported by the vnc protocol, so we still have
to do the translation 24 bpp -> 32 bpp.
