Rename the existing xendev 'connect' op to 'initialised' and introduce
a new 'connected' op. This new op, if defined, is called when the
backend is connected. Note that since there is no state transition this
may be called more than once.

This patch updates the libxenctrl calls in Qemu to use the new interface,
otherwise Qemu wouldn't be able to build against new versions of the
library.
We check libxenctrl version in configure, from Xen 3.3.0 to Xen
unstable.

Since version 4.4.x, gcc supports additional format attributes.
__attribute__ ((format (gnu_printf, 1, 2)))
should be used instead of
__attribute__ ((format (printf, 1, 2))
because QEMU always uses standard format strings (even with mingw32).
The patch replaces format attribute printf / __printf__ by macro
GCC_FMT_ATTR which uses gnu_printf if supported.
It also removes an #ifdef __GNUC__ (not needed any longer).

Changing block.h or blockdev.h resulted in recompiling most objects.
Move DriveInfo typedef and BlockInterfaceType enum definitions
to qemu-common.h and rearrange blockdev.h use to decrease churn.

All of these users have global state so we really don't see a benefit from
exit_notifier. However, using exit_notifier means that there's one less
justification for having global state in the first place.

Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc923584,
f40d753718,
96555a96d7 and
3990d09adf but the fixes were fragile.
Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

This adds domain building support for paravirtual domains to qemu.
This allows booting xen guests directly with qemu, without Xend
and the management stack.

This patch makes qemu create backend and frontend device entries in
xenstore for devices configured on the command line. It will use
qdisk and qnic backend names, so the qemu internal backends will
be used.
Disks can be created using -drive if=xen,file=...
Nics can be created using -net nic,macaddr=...

This patch adds a network interface backend driver to qemu. It is a pure
userspace implemention using the gntdev interface. It uses "qnet" as
backend name in xenstore so it doesn't interfere with the netback
backend (aka "vnif").
The network backend is hooked into the corrosponding qemu vlan, i.e.
vif 0 is hooked into vlan 0. To make the packages actually arrive
somewhere you additionally have to link the vlan to the outside world
using the usual qemu command line options such as "-net tap,...".

This patch adds a frsamebuffer (and kbd+mouse) backend driver. It
it based on current xen-unstable code. It has been changed to make

This patch adds infrastructure for xen backend drivers living in qemu,
