The ICH9 PCI device uses qemu_init_irq() in its instance_init method,
but fails to clean it up in its uninit. This results in a leak,
detected by ASAN when running the device-introspect-test:
Direct leak of 96 byte(s) in 1 object(s) allocated from:

We could call qemu_free_irq() in pci_ich9_uninit(), but
since we have a method of initializing the IRQ that doesn't
need manual freeing, use that instead: qemu_init_irq_child().

In some adhoc profiling booting Linux VMs, it's observed that ahci_irq_lower()
can be a hot path (10000+ triggers until login prompt appears). Even though the
parent device never changes, this method re-determines whether the parent device
is a PCI device or not using the rather expensive object_dynamic_cast()
function. Avoid this overhead by pushing the interrupt handling to the parent
device, essentially turning AHCIState into an "IP block".
Note that this change also frees AHCIState from the PCI dependency which wasn't
reflected in Kconfig.

In my "build everything" tree, changing hw/hw.h triggers a recompile
of some 2600 out of 6600 objects (not counting tests and objects that
don't depend on qemu/osdep.h).
The previous commits have left only the declaration of hw_error() in
hw/hw.h. This permits dropping most of its inclusions. Touching it
now recompiles less than 200 objects.

recompile of some 2700 out of 6600 objects (not counting tests and

hw/hw.h supposedly includes it for convenience. Several other headers
include it just to get VMStateDescription. The previous commit made
that unnecessary.
Include migration/vmstate.h only where it's still needed. Touching it
now recompiles only some 1600 objects.

After reviewing a patch from Philippe that removes block-backend.h
from hw/lm32/milkymist.c, I noticed that this header is included
unnecessarily in a lot of other files, too. Remove those unneeded
includes to speed up the compilation process a little bit.

Add INTERFACE_CONVENTIONAL_PCI_DEVICE to all direct subtypes of
TYPE_PCI_DEVICE, except:
1) The ones that already have INTERFACE_PCIE_DEVICE set:
* base-xhci
* e1000e
* nvme
* pvscsi
* vfio-pci
* virtio-pci
* vmxnet3
2) base-pci-bridge
Not all PCI bridges are Conventional PCI devices, so
INTERFACE_CONVENTIONAL_PCI_DEVICE is added only to the subtypes
that are actually Conventional PCI:
* dec-21154-p2p-bridge
* i82801b11-bridge
* pbm-bridge
* pci-bridge
The direct subtypes of base-pci-bridge not touched by this patch
are:
* xilinx-pcie-root: Already marked as PCIe-only.
* pcie-pci-bridge: Already marked as PCIe-only.
* pcie-port: all non-abstract subtypes of pcie-port are already
marked as PCIe-only devices.
3) megasas-base
Not all megasas devices are Conventional PCI devices, so the
interface names are added to the subclasses registered by
megasas_register_types(), according to information in the
megasas_devices[] array.
"megasas-gen2" already implements INTERFACE_PCIE_DEVICE, so add
INTERFACE_CONVENTIONAL_PCI_DEVICE only to "megasas".
