  Hi folks,

This is the fourth version of the xen support for qemu patch series,
addressing review comments.  Also fixed some bugs and made the
backend drivers restartable (for boots via pvgrub).  New in this
submission is the domain building support.

The console and framebuffer backend drivers are largely based on the
xen code, the other bits are rewritten from scratch.  Nevertheless
the code should be functionally identical.

Overview (individual patches have longer descriptions):

  #1  -- Handle terminating signals.
  #2  -- add DisplayState->idle
  #3  -- add container_of() macro to osdep.h
  #4  -- move GUI_REFRESH_INTERVAL define from vl.c to console.h

  #5  -- groundwork: build system, cmd line options, ...
  #6  -- xen backend driver infrastructrure
  #7  -- xen console backend driver
  #8  -- xen framebuffer backend driver

  #9  -- xen block backend driver
  #10 -- xen nic backend driver
  #11 -- allow xen disks and nics being configured via qemu command
         line options.
  #12 -- set vnc password from xenstore.
  #13 -- xen: pv domain builder.

The first four patches are preparing patches.  They put some stuff in
place the other xen patches depend on.

With the next four patches in place upstream qemu can replace xen's
qemu-dm for paravirtual domains.

The last five patches add full userspace implementations of block and
nic backend drivers using the grant table device (gntdev), command
line support config support for setting up these backends and domain
building support.

xen support is implemented using another machine type.  xen's qemu-dm
already uses the machine type to switch between paravirtualized and
fully virtualized machines, so this was the natural choice.  qemu has
gets a new "xenpv" machine type additionally to the "pc" and "isapc"

The patches are also available here:

There is also a patch queue for qemu-dm, so the patches can get a
test-drive there:

There also a '-b' (no whitespace changes) version for easier review:

The qemu-dm patch series has a slightly different ordering to make the
patch queue more bisect-friendly.  Also some preparing patches are not
needed because they already there.  Some extra patches (backports) are
there due to the age of the qemu-dm tree.  The last two patches are not
present (yet).
