docs: tweak kernel-doc for QEMU coding standards
Surprisingly, QEMU does have a pretty consistent doc comment style and
it is not very different from the Linux kernel's. Of the documentation
"sigils", only "#" separates the QEMU doc comment style from Linux's,
and it has 200+ instances vs. 6 for the kernel's '&struct foo' (all in
accel/tcg/translate-all.c), so it's clear that the two standards are
different in this respect. In addition, our structs are typedefed and
recognized by CamelCase names.
Adjust kernel-doc's parser for these two aspects of the QEMU coding
standards. The patch has been valid, with hardly any change, for over
two years, so it should not be an issue to keep kernel-doc in sync with

object: Improve documentation of interfaces
QOM interfaces allow a limited form of multiple inheritance, at the
condition of being stateless. That is, they cannot be instantiated
and a pointer to an interface shouldn't be dereferenceable in any way.
This is achieved by making the QOM instance type an incomplete type,
which is, as mentioned by Markus Armbruster, the closest you can get
to abstract class in C.
Incomplete types are widely used to hide implementation details, but
people usually expect to find at least one place where the type is
fully defined. The fact that it doesn't happen with QOM interfaces is
quite disturbing, especially since it isn't documented anywhere as
recently discussed in this thread:

Devices "ivshmem-plain" and "ivshmem-doorbell" support only MSI-X.
Config space register Interrupt Pin is zero. Device "ivshmem"
additionally supported legacy INTx, but it was removed in commit 5a0e75f0a9 "hw/misc/ivshmem: Remove deprecated "ivshmem" legacy
device". The commit left ivshmem_update_irq() behind. Since the
Interrupt Pin register is zero, the function does nothing. Remove it.

pseries: disable migration-test if /dev/kvm cannot be used
On ppc64, migration-test only works with kvm_hv, and we already
have a check to verify the module is loaded.
kvm_hv module can be loaded in memory and /sys/module/kvm_hv exists,
but on some systems (like build systems) /dev/kvm can be missing
(by administrators choice).
And as kvm_hv exists test-migration is started but QEMU falls back to
TCG because it cannot be used:
Could not access KVM kernel module: No such file or directory
failed to initialize KVM: No such file or directory
Back to tcg accelerator
And as the test is done with TCG, it fails.
As for s390x, we must check for the existence and the access rights
of /dev/kvm.

Remove the core bluetooth code
It's been deprecated since QEMU v3.1. We've explicitly asked in the
deprecation message that people should speak up on qemu-devel in case
they are still actively using the bluetooth part of QEMU, but nobody
ever replied that they are really still using it.
I've tried it on my own to use this bluetooth subsystem for one of my
guests, but I was also not able to get it running anymore: When I was
trying to pass-through a real bluetooth device, either the guest did
not see the device at all, or the guest crashed.
Even worse for the emulated device: When running
qemu-system-x86_64 -bt device:keyboard
QEMU crashes once you hit a key.
So it seems like the bluetooth stack is not only neglected, it is
completely bitrotten, as far as I can tell. The only attention that
this code got during the past years were some CVEs that have been
spotted there. So this code is a burden for the developers, without
any real benefit anymore. Time to remove it.
Note: hw/bt/Kconfig only gets cleared but not removed here yet.
Otherwise there is a problem with the *-softmmu/config-devices.mak.d
dependency files - they still contain a reference to this file which
gets evaluated first on some build hosts, before the file gets
properly recreated. To avoid breaking these builders, we still need
the file around for some time. It will get removed in a couple of
weeks instead.

The XSCOM bus is implemented with a QOM interface, which is mostly
generic from a CPU type standpoint, except for the computation of
addresses on the Pervasive Connect Bus (PCB) network. This is handled
by the pnv_xscom_pcba() function with a switch statement based on
the chip_type class level attribute of the CPU chip.
This can be achieved using QOM. Also the address argument is masked with
PNV_XSCOM_SIZE - 1, which is for POWER8 only. Addresses may have different
sizes with other CPU types. Have each CPU chip type handle the appropriate
computation with a QOM xscom_pcba() method.
