include/qemu/osdep.h: Don't include qapi/error.h
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.

hw/arm/allwinner-a10: Do not use nd_table in instance_init function
The instance_init function of a device can be called at any time, even
if the device is not going to be used (i.e. not going to be realized).
So a instance_init function must not do things that could cause QEMU
to exit, like calling qemu_check_nic_model(&nd_table[0], ...) for example.
But this is what the instance_init function of the allwinner-a10 device
is currently doing - and this causes QEMU to quit unexpectedly when
you run the 'device-list-properties' QMP command for example:
$ echo "{'execute':'qmp_capabilities'}"\
"{'execute':'device-list-properties',"\
" 'arguments':{'typename':'allwinner-a10'}}" \
| arm-softmmu/qemu-system-arm -M mps2-an505,accel=qtest -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2},
"package": "build-all"}, "capabilities": []}}
{"return": {}}
Unsupported NIC model: lan9118
... and QEMU quits after printing the last line (which should not happen
just because of running 'device-list-properties' here).
And with the cubieboard, this even causes QEMU to abort():
$ echo "{'execute':'qmp_capabilities'}"\
"{'execute':'device-list-properties',"\
" 'arguments':{'typename':'allwinner-a10'}}" \
| arm-softmmu/qemu-system-arm -M cubieboard,accel=qtest -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2},
"package": "build-all"}, "capabilities": []}}
{"return": {}}
Unexpected error in error_set_from_qdev_prop_error() at hw/core/qdev-properties.c:1095:
Property 'allwinner-emac.netdev' can't take value 'hub0port0', it's in use
Aborted (core dumped)
To fix the problem we've got to move the offending code to the realize
function instead.
