packets the guest doesn't want to see.

Add a new RX_MODE control virtqueue class with commands PROMISC and
ALLMULTI and usage documented in virtio-net.h allowing the guest to
manipulate packet receiving options. We don't export a feature for
this until we also add the MAC filter table.
Note, for compatibility with older guest drivers we need to default
to promiscuous.

This will be used for RX mode, MAC table, VLAN table control, etc...
The control transaction consists of one or more "out" sg entries and
one or more "in" sg entries. The first out entry contains a header
defining the class and command. Additional out entries may provide
data for the command. A response via the ack entry is required
and the guest will typically be waiting for it.

Memory allocation failures are a very rare condition on virtual-memory
hosts. They are also very difficult to handle correctly (especially in a
hardware emulation context). Because of this, it is better to gracefully
terminate emulation rather than executing untested or even unwritten recovery
code paths.
This patch changes the qemu memory allocation routines to terminate emulation
if an allocation failure is encountered.

As part of my ongoing effort to make nested SVM useful, I started working to get
VMware ESX run inside KVM.
VMware couples itself pretty tightly to the CPUID, so it's a good idea to emulate
a machine that officially supports SVM and should thus exploit the powers of
nested virtualization.
This patch adds a Phenom CPU identifier, that resembles a real-world phenom
CPU as closely as possible.

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.

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

used later in this patch series.
