VFIOAddressSpace is a common object used by VFIOContainerBase which is
declared in "hw/vfio/vfio-container-base.h". Move the VFIOAddressSpace
related services into "container-base.c".
While at it, rename :
vfio_get_address_space -> vfio_address_space_get
vfio_put_address_space -> vfio_address_space_put
to better reflect the namespace these routines belong to.

Gather all VFIORegion related declarations and definitions into their
own files to reduce exposure of VFIO internals in "hw/vfio/vfio-common.h".
They were introduced for 'vfio-platform' support in commits
db0da029a1 ("vfio: Generalize region support") and a664477db8
("hw/vfio/pci: Introduce VFIORegion").
To be noted that the 'vfio-platform' devices have been deprecated and
will be removed in QEMU 10.2. Until then, make the declarations
available externally for 'sysbus-fdt.c'.

The migration core subsystem makes use of the VFIO migration API to
collect statistics on the number of bytes transferred. These services
are declared in "hw/vfio/vfio-common.h" which also contains VFIO
internal declarations. Move the migration declarations into a new
header file "hw/vfio/vfio-migration.h" to reduce the exposure of VFIO
internals.
While at it, use a 'vfio_migration_' prefix for these services.
To be noted, vfio_migration_add_bytes_transferred() is a VFIO
migration internal service which we will be moved in the subsequent
patches.

Targets know whether they are big-endian more than they know if
the endianness is different from the host: the former is mostly
a constant, at least in machine creation code, while the latter
has to be computed with TARGET_BIG_ENDIAN != HOST_BIG_ENDIAN or
something like that.
load_aout, however, takes a "bswap_needed" argument. Replace
it with a "big_endian" argument; even though all users are
big-endian, it is cheap enough to keep the optional swapping
functionality even for little-endian boards.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
We have some users of the PL011 struct which embed it directly into
their own state structs. This means that the Rust version of the
device must have a state struct that is the same size or smaller
than the C struct.
In commit 9b642097d6 ("rust: pl011: switch to safe chardev operation")
the Rust PL011 state struct changed from having a bindings::CharBackend
to a chardev::CharBackend, which made it grow larger than the C
version. This results in an assertion at startup when QEMU was
built with Rust enabled:
$ qemu-system-arm -M raspi2b -display none
ERROR:../../qom/object.c:562:object_initialize_with_type: assertion
failed: (size >= type->instance_size)
The long-term better approach to this problem would be to move
our C device code patterns away from "embed a struct" and (back)
to "have a pointer to the device", so we can make the C PL011State
struct a private implementation detail rather than exposed to
its users.
For the short term, add a padding field at the end of the C struct
so it's big enough that the Rust state struct can fit.

Rather than use the hardcoded define throughout the tree for the
PNOR LPC address, keep it within the PnvPnor object.
This should solve a dead code issue in the BMC HIOMAP checks where
Coverity (correctly) reported that the sanity checks are dead code.
We would like to keep the sanity checks without turning them into a
compile time assert in case we would like to make them configurable
in future.

Previously the ctrl virtqueue was handled in the AioContext where SCSI
requests are processed. When IOThread Virtqueue Mapping was added things
become more complicated because SCSI requests could run in other
AioContexts.
Simplify by handling the ctrl virtqueue in the main loop where reset
operations can be performed. Note that BHs are still used canceling SCSI
requests in their AioContexts but at least the mean loop activity
doesn't need BHs anymore.
