A guest user may set channel frame count via es1370_write()
such that, in es1370_transfer_audio(), total frame count
'size' is lesser than the number of frames that are processed
'cnt'.
int cnt = d->frame_cnt >> 16;
int size = d->frame_cnt & 0xffff;
if (size < cnt), it results in incorrect calculations leading
to OOB access issue(s). Add check to avoid it.

Finally add audiodev= options to audio frontends so users can specify
which backend to use when multiple backends exist. Not specifying an
audiodev= option currently causes the first audiodev to be used, this is
fixed in the next commit.
Example usage: -audiodev pa,id=foo -device AC97,audiodev=foo

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.

In my "build everything" tree, changing migration/vmstate.h triggers a
recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).
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.

I had to include an enum for audio sampling formats into qapi, but that
meant duplicating the audfmt_e enum. This patch replaces audfmt_e and
associated values with the qapi generated AudioFormat enum.
This patch is mostly a search-and-replace, except for switches where the
qapi generated AUDIO_FORMAT_MAX caused problems.

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".

After previous Peter patch, they are redundant. This way we don't
assign them except when needed. Once there, there were lots of case
where the ".fields" indentation was wrong:
.fields = (VMStateField []) {
and
.fields = (VMStateField []) {
Change all the combinations to:
.fields = (VMStateField[]){
The biggest problem (appart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.
