Many of these are marked as "intentional/fix required" because they
just need adding a fall through comment. This is exactly what this
patch does, except for target/mips/translate.c where it is easier to
duplicate the code, and hw/audio/sb16.c where I consulted the DOSBox
sources and decide to just remove the LOG_UNIMP before the fallthrough.

Fix outgoing migration which was crashing in
vmstate_hda_audio_stream_buf_needed, I think the problem
is that we have room for upto 4 streams in the array but only
use 2, when we come to try and save the state of the unused
streams we hit st->state == NULL.

Currently, the HDA device tries to sync itself with the QEMU audio
backend by waiting for the guest driver to handle buffer completion
interrupts. This causes the backend to often read too much data from the
device, as well as running out of data whenever the guest takes too long
to handle the interrupt.
According to the HDA specification, the guest is also not required to
use interrupts, but can also sync itself by polling the LPIB registers.
This patch will introduce high frequency (1000Hz) timers that interface
with the device and allow for much smoother emulation of the LPIB
registers. Since the timing is now provided by these timers, the need
to wait for buffer completion interrupts also ceases.

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".

had an error_report/return case.

cannot_instantiate_with_device_add_yet was introduced by commit
efec3dd631 to replace no_user. It was
supposed to be a temporary measure.
When it was introduced, we had 54
cannot_instantiate_with_device_add_yet=true lines in the code.
Today (3 years later) this number has not shrunk: we now have
57 cannot_instantiate_with_device_add_yet=true lines. I think it
is safe to say it is not a temporary measure, and we won't see
the flag go away soon.
Instead of a long field name that misleads people to believe it
is temporary, replace it a shorter and less misleading field:
user_creatable.
