The LDST macro is used to generate ldc and stc instructions that work with a
specific register. However, the SGR register only supports stc up to SH4A,
which supports both stc and ldc. This patch creates two sub-macros named LD
and ST that handle generating ldc and stc instructions separately, and
redeclares LDST to use these sub-macro.

Intel Macs have a chip called the "AppleSMC" which they use to control
certain Apple specific parts of the hardware, like the keyboard background
light.

That chip is also used to store a key that Mac OS X uses to decrypt binaries.

This patch adds emulation for that chip, so we're getting one step further
to having Mac OS X run natively on Qemu.

Set PCI multi-function bit according to multifunction property.
PCI address, devfn ,is exported to users as addr property,
so users can populate pci function(PCIDevice in qemu)
at arbitrary devfn.
It means each function(PCIDevice) don't know whether pci device
(PCIDevice[8]) is multi function or not.
So this patch allows user to set multifunction bit via property
and checks whether multifunction bit is set correctly.

Don't overwrite pci header type.
Otherwise, multi function bit which pci_init_header_type() sets
appropriately is lost.
Anyway PCI_HEADER_TYPE_NORMAL is zero, so it is unnecessary to zero

run qemu and issue info pci to see whether a device in question is
normal device, not pci-to-pci bridge.
This is handy because guest os isn't required.

With these two pieces in place, we can start naming ramblocks.  When
the device is present and it lives on a bus that provides a device
path, we concatenate the path and the provided name.  Otherwise we
just use name.  The resulting id string must be unique.  For now we
assume an allocation for the same name and size is a device that has
been removed and reinserted and return the same block.  This will go
away once qemu_ram_free() is implemented.

For callers that pass a device we can traverse up the qdev tree and
make use of the BusInfo.get_dev_path information for creating unique
savevm id strings.  This avoids needing to rely on the instance number,
which can cause problems with device initialization order and hotplug.

For compatibility, we also store away the old id string and instance
so we can accept migrations from VMs as we add new get_dev_path
implementations.
