Scenario:
- There is a non multifunction pci device A on 00:0X.0.
- Hot-plug another multifunction pci device B at 00:0X.1.
- The operation will fail of course.
- Try to hot-plug the B device 2-3 more times, qemu will crash.
Reason: The error flow leaves the B's address space into global address spaces
list, but the device object is freed. Fixed that.

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).

Add ACPI based PCI hotplug library with bridge hotplug
support.
Design
- each bus gets assigned "bsel" property.
- ACPI code writes this number
to a new BNUM register, then uses existing
UP/DOWN registers to probe slot status;
to eject, write number to BNUM register,
then slot into existing EJ.
The interface is actually backwards-compatible with
existing PIIX4 ACPI (though not migration compatible).
This is split out from PIIX4 codebase so we can
reuse it for Q35 as well.

use it in the qemu load/store routines in replacement of load/store +
bswap. Note that for 16-bit unsigned loads, movbe + movzw is basically the

P_REXW is defined has a constant at the beginning of i386/tcg-target.c,

the purpose of a constant.
Fix that by using a conditional expression operator instead of a shift.
On x86 this actually makes the code slightly smaller as GCC does in
practice (opc >> 8) & 8 instead of (opc & 0x800) >> 8 so the constants
are smaller to load.
