Implement support for using the KVM in-kernel GIC for ARM.

Convert the ARM GIC classes to use init/realize rather than
SysBusDevice::init. (We have to do them all in one patch to
avoid unconverted subclasses calling a nonexistent SysBusDevice
init function in the base class and crashing.)

Add presave/postload hooks to the ARM GIC common base class.
These will be used by the KVM in-kernel GIC subclass to sync
state between kernel and userspace when migrating.

During the review of the dataplane code, the EventPoll API morphed itself
(not concidentially) into something very very similar to an AioContext.
Thus, it is trivial to convert virtio-blk-dataplane to use AioContext,
and a first baby step towards letting dataplane talk directly to the
QEMU block layer.
The only interesting note is the value-copy of EventNotifiers. At least
in my opinion this is part of the EventNotifier API and is even portable
to Windows. Of course, in this case you should not close the notifier's
underlying file descriptors or handle with event_notifier_cleanup.

virtio-blk registers a vmstate change handler. Unfortunately this
handler is not unregistered on unplug, leading to some random
crashes if the system is restarted, e.g. via virsh reboot.
Lets unregister the vmstate change handler if the device is removed.

in the initialisation of the second macio DMA device which could cause some

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.

qdev-monitor.c is the only "core qdev" file that is not used in
user-mode emulation, and it does not define anything that is used
by hardware models. Remove it from the hw/ directory and
remove hw/qdev-monitor.h from hw/qdev.h too; this requires
some files to have some new explicitly includes.

Currently, M25P80 uses an object property to differentiate between flash parts.
Changed this over to use QOM sub-classes - the actual names of the different parts
are used to create a set of dynamic classes which passes the part info as class
data. The object no longer needs to search the known_devices table for itself,
instead it just gets its info from its own class.
Kept the intermediate class definition private to m25p80.c for the moment, as
the expectation is parts will only be added as new entries in the table. We can
factor out the TYPE_M25P80 abstraction into a header on a demand basis.

In QEMU emulation, there is no functional difference between the ARM mpcore
private timers and watchdogs. Removed all the distinction between the two from
arm_mptimer.c and converted it to be just the mptimer. a9mpcore and arm11mpcore
just instantiate the same mptimer object twice to get both timer and WDT.
If in the future we want to make the WDT functionally different then we can use
either QOM hierarchy to derive WDT from from mptimer, or we can add a property
"is-wdt" or some such.

The code for handling the default "unknown command state" case in
pflash_read in pflash_cfi01.c comments "reset state & treat it as
a read". However the code doesn't actually do this. Moving the
default case to the top of the switch so it can fall through into
the read case brings this file into line with pflash_cfi02 and
makes the code behave as the comments suggest.
The pflash_cfi01 code has always had this bug -- it was presumably
introduced when the original author copied the cfi02 code and
rearranged the order of the switch statement without noticing
that the default case relied on the fall-through.

The Intel flash command set requires that a read operation after
doing a 'single byte write' command returns the status register;
add this case to pflash_read() so we return the correct information.
Similarly, the case for the 0x28 flavour of block erase was missing.

This patch addresses the issue fully described here:
http://lists.nongnu.org/archive/html/qemu-devel/2013-02/msg01804.html
Linux kernels prior to 2.6.36 do not disable the PCI device during
enumeration process. Since lower and higher parts of a 64bit BAR
are programmed separately this leads to qemu receiving a request to occupy
a completely wrong address region for a short period of time.
We have found that the boot process screws up completely if kvm-apic range
is overlapped even for a short period of time (it is fine for other
regions though).
This patch raises the priority of the kvm-apic memory region, so it is
never pushed out by PCI devices. The patch is quite safe as it does not
touch memory manager.

Edivaldo reports a problem that the array of NetClientState in NICState is too
large - MAX_QUEUE_NUM(1024) which will wastes memory even if multiqueue is not
used.
Instead of static arrays, solving this issue by allocating the queues on demand
for both the NetClientState array in NICState and VirtIONetQueue array in
VirtIONet.
Tested by myself, with single virtio-net-pci device. The memory allocation is
almost the same as when multiqueue is not merged.

This fixes two bugs related to memory sync during
migration:
- ram address calculation was missing the chunk
address, so the wrong page was dirtied
- one after last was used instead of the
end address of a region, which might overflow to 0
and cause us to skip the region when the region ends at
~0x0ull.
