also make handler edge based to avoid losing events, the same as
it has been done for PCI and CPU hotplug handlers.

to make it more generic, so it could be used for memory hotplug
as well.

As reported in
http://article.gmane.org/gmane.comp.emulators.qemu/253987
Mac OSX actually requires describing all occupied slots
in ACPI - even if hotplug isn't enabled.
I didn't expect this so I dropped description of all
non hotpluggable slots from ACPI.
As a result: before
commit 99fd437dee468609de8218f0eb3b16621fb6a9c9 (enable
hotplug for pci bridges), PCI cards show up in the "device tree" of OS X
(System Information). E.g., on MountainLion users have:
Hardware -> PCI Cards:
Card Type Driver Installed Slot
*ethernet Ethernet Controller Yes PCI Slot 2
pci8086,2934 USB UHC Yes PCI Slot 29
ethernet:
Type: Ethernet Controller
Driver Installed: Yes
MSI: No
Bus: PCI

Vendor ID: 0x8086
Device ID: 0x100e

After commit 99fd437dee468609de8218f0eb3b16621fb6a9c9, users get:
Hardware -> PCI Cards:
This computer doesn't contain any PCI cards. If you installed PCI
cards, make sure they're properly installed.
Hardware -> Ethernet Cards
ethernet:
Type: Ethernet Controller
Bus: PCI
Vendor ID: 0x8086

Ethernet still works, but it's not showing up on the PCI bus, and it
no longer thinks it's plugged in to slot #2, as it used to before the
change.
To fix, append description for all occupied non hotpluggable PCI slots.
One need to be careful when doing this: VGA devices
are now described in SSDT, so we need to drop description from DSDT.
And ISA devices are used in DSDT so drop them from SSDT.

.. so that they might not be used by PCI devices.
Note:
Resort to concatenating templates with preprocessor help,
because 1.0b spec isn't supporting ConcatenateResTemplate,
as result Windows XP fails to execute PCI0._CRS method if
ConcatenateResTemplate() is used.

This enables support for device hotplug behind
pci bridges. Bridge devices themselves need
to be pre-configured on qemu command line.
Design:
- at machine init time, assign "bsel" property to bridges with
hotplug support
- dynamically (At ACPI table read) generate ACPI code to handle
hotplug events for each bridge with "bsel" property
Note: ACPI doesn't support adding or removing bridges by hotplug.
We detect and prevent removal of bridges by hotplug,
unless they were added by hotplug previously
(and so, are not described by ACPI).

AppleSMC (-device isa-applesmc) is required to boot OS X guests.
OS X expects a SMC node to be present in the ACPI DSDT. This patch
adds a SMC node to the DSDT, and dynamically patches the return value
of SMC._STA to either 0x0B if the chip is present, or otherwise to 0x00,
before booting the guest.

The ASL Optimizing Compiler version 20130823-32 [Sep 11 2013] issues the

After changing the parameter from `NotSerialized` to `Serialized`, the
remark is indeed gone and there is no size change.
The remark was added in ACPICA version 20130517 [1] and gives the
following explanation.
If a thread blocks within the method for any reason, and another thread
enters the method, the method will fail because an attempt will be
made to create the same (named) object twice.
In this case, issue a remark that the method should be marked
serialized. ACPICA BZ 909.

This adds ASL code as well as scripts for processing it,

commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd
Will be used for runtime acpi table generation.
Note:
This patch reuses some code from SeaBIOS, which was originally under
LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This
relicensing has been acked by all contributors that had contributed to the
code since the v2->v3 relicense. ACKs approving the v2+ relicensing are
listed below. The list might include ACKs from people not holding
copyright on any parts of the reused code, but it's better to err on the
side of caution and include them.
