  xio3130_downstream: Report error if pcie_chassis_add_slot() failed

On commit f8cd1b02 ("pci: Convert to realize"), no error_set*()
call was added for the pcie_chassis_add_slot() error case.
pcie_chassis_add_slot() errors get ignored, making QEMU crash
later.  e.g.:

  $ qemu-system-x86_64 -device ioh3420 -device xio3130-downstream
  qemu-system-x86_64: memory.c:2166: memory_region_del_subregion: Assertion 
`subregion->container == mr' failed.
  Aborted (core dumped)

Fix it by reporting the error using error_setg().

  pci: Set err to errp directly rather than through error_propagate()

ioh3420_interrupts_init() pass error message to local_err, then
propagate it to errp by error_propagate(), which is not necessary.
So eliminate it and pass errp directly instead of local_err.

  fw_cfg: add write callback

Reintroduce the write callback that was removed when write support was
removed in commit 023e3148567ac898c7258138f8e86c3c2bb40d07.

Contrary to the previous callback implementation, the write_cb
callback is called whenever a write happened, so handlers must be
ready to handle partial write as necessary.

  virtio/vhost: reset dev->log after syncing

vhost_log_put() is called to decomission the dirty log between qemu and
a vhost device when stopping the device. Such a call can happen from
migration_completion().

Present code sets dev->log_size to zero too early in vhost_log_put(),
causing the sync check to always return false. As a consequence, the
last pass on the dirty bitmap never happens at the end of migration.

If a vhost device was busy (writing to guest memory) until the last
moments before vhost_virtqueue_stop(), this error will result in guest
memory corruption (at least) following migrations.

  hw/pci-bridge/pcie_pci_bridge: properly handle MSI unavailability case

QEMU with the pcie-pci-bridge device crashes if the guest board doesn't support 
MSI,
e.g. 'qemu-system-ppc64 -M prep -device pcie-pci-bridge'.
This is caused by wrong pcie-pci-bridge instantiation error handling. This 
patch fixes this issue
by falling back to legacy INTx if MSI is not available.
Also set the bridge's 'msi' property default value to 'auto' in order to 
trigger errors
only when user explicitly set msi=on.

flag and/or conditional pcie_endpoint_cap_init() calls:

* vfio-pci (is_express=1, but legacy PCI handled by
  vfio_populate_device())
* vmxnet3 (is_express=0, but PCIe handled by vmxnet3_realize())
* pvscsi (is_express=0, but PCIe handled by pvscsi_realize())
* virtio-pci (is_express=0, but PCIe handled by
  virtio_pci_dc_realize(), and additional legacy PCI code at
  virtio_pci_realize())
* base-xhci (is_express=1, but pcie_endpoint_cap_init() call
  is conditional on pci_bus_is_express(dev->bus)
  * Note that xhci does not clear QEMU_PCI_CAP_EXPRESS like the
    other hybrid devices

  pci: Add INTERFACE_CONVENTIONAL_PCI_DEVICE to Conventional PCI devices

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".

  virtio: fix descriptor counting in virtqueue_pop

While changing the s/g list allocation, commit 3b3b0628
also changed the descriptor counting to count iovec entries
as split by cpu_physical_memory_map(). Previously only the
actual descriptor entries were counted and the split into
the iovec happened afterwards in virtqueue_map().
Count the entries again instead to avoid erroneous
"Looped descriptor" errors.

  virtio-pci: Replace modern_as with direct access to modern_bar

The modern bar is accessed now via yet another address space created just
for that purpose and it does not really need FlatView and dispatch tree
as it has a single memory region so it is just a waste of memory. Things
get even worse when there are dozens or hundreds of virtio-pci devices -
since these address spaces are global, changing any of them triggers
rebuilding all address spaces.

This replaces indirect accesses to the modern BAR with a simple lookup
and direct calls to memory_region_dispatch_read/write.

This is expected to save lots of memory at boot time after applying:

  isapc: Remove unnecessary migration compatibility code

We don't touch isapc when we change guest ABI and add new entries
to PC_COMPAT_* or new PCMachineClass compat flags.  This means
isapc never guaranteed guest ABI and cross-QEMU-version live
migration compatibility.  There's no point in keeping code for
kvm-pv-eoi and APIC ID compatibility in pc_init_isa().

hot_add_cpu is set in pc_machine_class_init(), so we don't

  tests/pxe: Test more NICs when running in SPEED=slow mode

The pxe-test is a very good test to excercise NICs, thus we should use
it to test all NICs that can be used by the BIOS for booting via network.
However, to avoid that the default testing time increases too much, the
additional NICs are only tested in the "make check SPEED=slow" mode.

The virtio-net NIC on ppc64 is now also only tested in slow mode, since
the test on ppc64 is really quite slow and we've got test coverage for
virtio-net in big endian mode now on s390x, too.

A bunch of fixes all over the place.
A new vmcore device - the user interface around it is still somewhat
controversial, but I feel most of the code is fine, suggestions can be
addressed by adding patches on top.
