qdev: rework device properties.
This patch is a major overhaul of the device properties. The properties
are saved directly in the device state struct now, the linked list of
property values is gone.
Advantages:
* We don't have to maintain the list with the property values.
* The value in the property list and the value actually used by
the device can't go out of sync any more (used to happen for
the pci.devfn == -1 case) because there is only one place where
the value is stored.
* A record describing the property is required now, you can't set
random properties any more.
There are bus-specific and device-specific properties. The former
should be used for properties common to all bus drivers. Typical
use case is bus addressing, i.e. pci.devfn and i2c.address.
Properties have a PropertyInfo struct attached with name, size and
function pointers to parse and print properties. A few common property
types have PropertyInfos defined in qdev-properties.c. Drivers are free
to implement their own very special property parsers if needed.
Properties can have default values. If unset they are zero-filled.

fix segfault in setting migration speed
Hi,
Whoever wrote this migrate_set_speed function is totally stupid.
Any failed or completed migration keeps its state to allow probing of
migration data, but has no associated file anymore. It is, thus,
possible to crash qemu by calling migrate_set_speed after a migration
is finished (or failed, or cancelled), but before another one starts.

ioport: use uint{32, 16, 8}_t for ioport value and pio_addr_t for ioport address.
Using int for cpu_{in, out}[bwl] is inconsistent with other part

At least, softmmu, CPU{Read, Write}MemoryFunc, pci, target_phys_addr_t

This patch removes the inconsistency.
IO port has its own address space so define pio_addr_t as uint32_t
because PCI io space width is 32bit.
And use uint{32, 16, 8}_t for ioport value.
Changing signedness of value might cause subtle issue. However
only a suspicious caller is kvm_handle_io() which is ok. And other callers
pass unsigned value in the first place.

honor -S on incoming migration
-S is not honored by qemu on incoming migration. If a domain is migrated
while paused, thus, it will start running on the remote machine; this
is wrong.
Given the trivial patch to fix this, it looks more like a thinko
than anything else, probably dating back to the qemu-kvm merge.
The interesting part is that the -S mechanism was in fact *used* when
migrating (setting autostart = 0) and the incoming migration code was
starting the VM at the end of the migration.
Since I was removing the vm_start from there, I also corrected a related
imprecision. The code was doing a vm_stop "just in case", but we can
be sure that the VM is not running---the vm_start call in vl.c has not
been reached yet. So the vm_stop is removed together with the vm_start.

register--for getting the register numbers to line up for
newer (XML-aware) and older (non-XML-aware) GDB. While this hack worked
in some cases, it didn't work in all cases, notably when the user used
`finish' or `continue': GDB would attempt to read the non-existent
register and QEMU would complain.
This patch fixes things up properly. Instead of inserting a fake
register, we explicitly declare the floating-point and SPE registers to
start at 71. This action accomplishes the same thing as the nasty hack,
except that now GDB never tries to fetch the non-existant register 70.

target-ppc: fix evmergelo and evmergelohi
For 32-bit PPC targets, we translated:
evmergelo rX, rX, rY
as:
rX-lo = rY-lo
rX-hi = rX-lo
which is wrong, because we should be transferring rX-lo first. This
problem is fixed by swapping the order in which we write the parts of
rX.
Similarly, we translated:
evmergelohi rX, rX, rY
as:
rX-lo = rY-hi
rX-hi = rX-lo
In this case, we can't swap the assignment statements, because that
would just cause problems for:
evmergelohi rX, rY, rX
Instead, we detect the first case and save rX-lo in a temporary
variable:
tmp = rX-lo
rX-lo = rY-hi
rX-hi = tmp
These problems don't occur on PPC64 targets because we don't split the
SPE registers into hi/lo parts for such targets.
