Spice deprecated this callback in 0.12.6.
It's not a problem yet, but it will cause Clang to fail in a -Werror
build due to the deprecated tag.

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h
everywhere. Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.
This commit was created with scripts/clean-includes.
NB: If this commit breaks compilation for your out-of-tree
patchseries or fork, then you need to make sure you add
#include "qemu/osdep.h" to any new .c files that you have.

Live migration with spice works like this today:
(1) client_migrate_info monitor cmd
(2) spice server notifies client, client connects to target host.
(3) qemu waits until spice client connect is finished.
(4) send over vmstate (i.e. main part of live migration).
(5) spice handover to target host.
(3) is implemented by making client_migrate_info a async monitor
command. This is the only async monitor command we have.
The original reason to implement this dance was that qemu did not accept
new tcp connections while the incoming migration was running, so (2) and
(4) could not be done in parallel. That issue was fixed long ago though.
Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp
connects while the incoming migration runs.
Time to drop step (3). This patch does exactly that, by making the
monitor command synchronous and removing the code needed to handle the
async monitor command in ui/spice-core.c

Commit 7572150 adopted QERR_DEVICE_NOT_ACTIVE for the purpose,
probably because adding another error seemed cumbersome overkill.
Produces "No spice device has been activated", which is awkward.
We've since abandoned our quest for "rich" error objects. Time to
undo the damage to this error message. Replace it by "SPICE is not in
use".
Keep the stupid DeviceNotActive ErrorClass for compatibility, even
though Libvirt doesn't use it.

This patch fixes spice display initialization to handle
multihead properly.
spice-core now keeps track of which QemuConsole has a spice
display channel attached to it and which has not. It also
manages display channel ids.
spice-display looks at all QemuConsoles and will pick up any
graphic console not yet bound to a spice channel (which in practice
are all non-qxl graphic devices).
Result is that
(a) you'll get a spice client window for each graphical device
now (first only without this patch), and
(b) mixing qxl and non-qxl vga cards works properly.

Spice has two display interface implementations: One integrated into
the qxl graphics card, and one generic which can operate with every
qemu-emulated graphics card.
The generic one is activated in case spice is used without qxl. The
logic for that only caught the "-vga qxl" case, "-device qxl-vga" goes
unnoticed. Fix that by adding a check in the spice interface
registration so we'll notice the qxl card no matter how it is created.

This patch adds 'spicevmc' and 'spiceport' support to qapi and also
switches over the spice chardev initialization to the new qapi code
path.
