To support definitions of s390 pci attributes in Qemu cmdline, we have
to make current S390PCIBusDevice struct inherit DeviceState and add
three properties for it. Currently we only support definitions of uid
and fid.
'uid' is optionally defined by users, identifies a zpci device and
must be defined with a 16-bit and non-zero unique value.
'fid' ranges from 0x0 to 0xFFFFFFFF. For fid property, we introduce a
new PropertyInfo by the name of s390_pci_fid_propinfo with our special
setter and getter. As 'fid' is optional, introduce 'fid_defined' to
track whether the user specified a fid.
'target' field is to direct qemu to find the corresponding generic PCI
device. It is equal to the 'id' value of one of generic pci devices.
If the user doesn't specify 'id' parameter for a generic pci device,
its 'id' value will be generated automatically and use this value as
'target' to create an associated zpci device.
If the user did not specify 'uid' or 'fid', values are generated
automatically. 'target' is required.
In addition, if a pci device has no associated zpci device, the code
will generate a zpci device automatically for it.

Currently each zpci device holds its own DMA address space and memory
region. At the same time, all instances of zpci device are stored in
S390pciState. So duirng the initialization of S390pciState, all zpci
devices are created and then all DMA address spaces are created. Thus,
when initializing pci devices, their corresponding DMA address spaces
could be found.
But zpci qdev will be introduced later. Zpci device may be initialized
and plugged afterwards generic pci device. So we should initialize all
DMA address spaces and memory regions before initializing zpci devices.
We introduce a new struct named S390PCIIOMMU. And a new field of
S390pciState, which is an array to store all instances of S390PCIIOMMU,
is added so that qemu pci code could find the corresponding DMA
address space when initializing a generic pci device. And this should
be done before the connection of a zpci device and a generic pci
device is built.

The previous patch moved virtual css bridge and bus out from
virtio-ccw, but kept the direct reference of virtio-ccw specific
unplug function inside css-bridge.c.
To make the virtual css bus and bridge useful for non-virtio devices,
this introduces a common unplug function pointer "unplug" to call
specific virtio-ccw unplug parts. Thus, the tight coupling to
virtio-ccw can be removed.
This unplug pointer is a member of CCWDeviceClass, which is introduced
as an abstract device layer called "ccw-device". This layer is between
DeviceState and specific devices which are plugged in virtual css bus,
like virtio-ccw device. The specific unplug handlers should be assigned
to "unplug" during initialization.

Currently, common base layers virtual css bridge and bus are
defined in hw/s390x/virtio-ccw.c(h). In order to support
multiple types of devices in the virtual channel subsystem,
especially non virtio-ccw, refactoring work needs to be done.
This work is just a pure code move without any functional change
except dropping an empty function virtual_css_bridge_init() and
virtio_ccw_busdev_unplug() changing. virtio_ccw_busdev_unplug()
is specific to virtio-ccw but gets referenced from the common
virtual css bridge code. To keep the functional changes to a
minimum we export this function from virtio-ccw.c and continue
to reference it inside virtual_css_bridge_class_init()
(now living in hw/s390x/css-bridge.c). A follow-up patch will

On a reboot, QEMU will reload its own BIOS, but use the migrated start

Fix this by not relying on the migrated values anymore, but still
provide them during migration, so existing QEMUs continue to work.

Rather than making the dealloc visitor track of stack of pointers
remembered during visit_start_* in order to free them during
visit_end_*, it's a lot easier to just make all callers pass the
same pointer to visit_end_*. The generated code has access to the
same pointer, while all other users are doing virtual walks and
can pass NULL. The dealloc visitor is then greatly simplified.
All three visit_end_*() functions intentionally take a void**,
even though the visit_start_*() functions differ between void**,
GenericList**, and GenericAlternate**. This is done for several
reasons: when doing a virtual walk, passing NULL doesn't care
what the type is, but when doing a generated walk, we already
have to cast the caller's specific FOO* to call visit_start,
while using void** lets us use visit_end without a cast. Also,
an upcoming patch will add a clone visitor that wants to use
the same implementation for all three visit_end callbacks,
which is made easier if all three share the same signature.
For visitors with already track per-object state (the QMP visitors
via a stack, and the string visitors which do not allow nesting),
add an assertion that the caller is indeed passing the same
pointer to paired calls.

Sector-based limits are awkward to think about; in our on-going
quest to move to byte-based interfaces, convert max_transfer_length
and opt_transfer_length. Rename them (dropping the _length suffix)
so that the compiler will help us catch the change in semantics
across any rebased code, and improve the documentation. Use unsigned
values, so that we don't have to worry about negative values and
so that bit-twiddling is easier; however, we are still constrained
by 2^31 of signed int in most APIs.
When a value comes from an external source (iscsi and raw-posix),
sanitize the results to ensure that opt_transfer is a power of 2.

Making all callers special-case 0 as unlimited is awkward,
and we DO have a hard maximum of BDRV_REQUEST_MAX_SECTORS given
our current block layer API limits.
In the case of scsi, this means that we now always advertise a
limit to the guest, even in cases where the underlying layers
previously use 0 for no inherent limit beyond the block layer.

s->blocksize may be larger than 512, in which case our
tweaks to max_xfer_len and opt_xfer_len must be scaled
appropriately.

Internal flag msi_used is uncesessary, msi_uninit() could be called
directly, msi_enabled() is enough to check device msi state.
But for migration compatibility, keep the field in structure.

Internal big flag E1000E_USE_MSI is unnecessary, also is the helper
function: e1000e_init_msi(), e1000e_cleanup_msi(), so, remove them all.

megasas overwrites user configuration when msi_init fail to flag internal msi
state, which is unsuitable. megasa_use_msi() is unnecessary, we can call
msi_uninit() directly when unrealize, even no need to call msi_enabled() first.

msi_init() reports errors with error_report(), which is wrong
when it's used in realize().
Fix by converting it to Error.
Fix its callers to handle failure instead of ignoring it.
For those callers who don't handle the failure, it might happen:
when user want msi on, but he doesn't get what he want because of
msi_init fails silently.
