Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

Now we have error_setg() we can improve the error message emitted if
you attempt to set a property of a device after the device is realized
(the previous message was "permission denied" which was not very
informative).

Add support for declaring array properties for qdev devices.
These work by defining an initial static property 'len-arrayname'
which the user of the device should set to the desired size
of the array. When this property is set, memory is allocated
for the array elements, and dynamic properties "arrayname[0]",
"arrayname[1]"... are created so the user of the device can
then set the values of the individual array elements.

Done with this script:
cd hw
for i in `find . -name '*.h' | sed 's/^..//'`; do
echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,'
done | sed -i -f - `find . -type f`
This is so that paths remain valid as files are moved.
Instead, files in hw/dataplane are referenced with the relative path.
We know they are not going to move to include/, and they are the only
include files that are in subdirectories _and_ move.

This patch adds basic multiqueue support for qemu. The idea is simple, an array
of NetClientStates were introduced in NICState, parse_netdev() were extended to
find and match all NetClientStates belongs to the backend and place their
pointers in NICConf. Then qemu_new_nic can setup a N:N mapping between NICStates
that belongs to a nic and NICStates belongs to the netdev. And a queue_index
were introduced in NetClientState to track its index. After this, each peers of
a NICState were abstracted as a queue.
After this change, all NetClientState that belongs to the same backend/nic has
the same id. When use want to change the link status, all NetClientStates that
belongs to the same backend/nic will be also changed. When user want to delete
a device or netdev, all NetClientStates that belongs to the same backend/nic
will be deleted also. Changing or deleting an specific queue is not allowed.

This separates the qdev properties code in two parts:
- qdev-properties.c, that contains most of the qdev properties code;
- qdev-properties-system.c for code specific for qemu-system-*,
containing:
- Property types: drive, chr, netdev, vlan, that depend on code that
won't be included on *-user
- qemu_add_globals(), that depends on qemu-config.o.
This change should help on two things:
- Allowing DeviceState to be used by *-user without pulling
dependencies that are specific for qemu-system-*;
- Writing qdev unit tests without pulling too many dependencies.
The copyright/license of qdev-properties.c isn't explicitly stated at
the file, so add a simple copyright/license header pointing to the
commit ID of the original file.

Header file dependency is a frickin' nightmare right now. cpu.h tends
to get included in our 'include everything' header files but qdev also
needs to include those headers mainly for qdev-properties since it knows
about CharDriverState and friends.
We can solve this for now by splitting out qdev.h along the same lines
that we previously split the C file. Then cpu.h just needs to include
qdev-core.h.
hw/qdev.h is split into following new headers:
hw/qdev-core.h
hw/qdev-properties.h
hw/qdev-monitor.h

[ehabkost: re-add DEFINE_PROP_PCI_HOST_DEVADDR, that was removed on the
original patch (by mistake, I guess)]
[ehabkost: kill qdev_prop_set_vlan() declaration]
[ehabkost: moved get_fw_dev_path() comment to the original location
(I don't know why it was moved)]
[ehabkost: removed qdev_exists() declaration]
[ehabkost: keep using 'QemuOpts' instead of 'struct QemuOpts', as
qdev-core.h includes qemu-option.h]
