meson: fix build of qemu-system-microblaze with --enable-modules
A previous commit wrongly skipped including the generated modinfo in
case hw_arch dictionary ends up being empty.
Fix that by adding an empty source set in dictionary in this case.

tests/functional: Enforce sha256 as hashsum algorithm for all tests
The functional testing framework currently supports both, sha256
and sha512 as hashsums for the assets. However, all but one test
currently only use sha256, which should also be sufficient according
to the current security standards. Having two algorithms around already
caused some confusion (e.g. the clean_functional_cache.py script only
supports sha256 right now), so standardize now on enforcing sha256
before more tests use a mix of the two algorithms.

The haiku VM bitrotted in the course of time. Make sure to use the
latest version of the repositories here and install missing pieces
like "pip" and "tomli" now.
Since we nowadays also install our own version of meson in our venv,
this also requires a change to our configure script: On Haiku, the
meson binary shows up as pyvenv/non-packaged/bin/meson here, and not
in the expected location pyvenv/bin/meson. Adjust the "meson" variable
to point to that Haiku-specific location to fix this issue. See also:
https://github.com/haiku/haiku/blob/r1beta5/docs/user/storage/storageintro.dox
And finally, with the new toolchain from the beta 5, we also have to
compile with "-pie", otherwise the linker complains about bad relocations
in the object files, so allow compiling with PIE in the configure script
now.

limit the test to Linux hosts now. We already have a decorator to

qdev: add hw/core/gpio.c to libhwcore
While GPIO functionality is not used by user-mode emulation, it is
conceptually part of qdev - GPIO pins are included in DeviceState
independent of whether this is system or user-mode emulation.
For the Rust bindings, having GPIO functionality in system_ss causes
a problem because, for simplicity, all methods of DeviceState are
included in the Rust hwcore crate. On Windows, rustc is not able
to do dead code elimination as well as on other OSes and this causes
an undefined symbol error, because gpio.c is not linked into the
rust/hw/core/rust-hwcore-rs-integration test binary.
To fix it, move gpio.c out of system_ss and into libhwcore.
Alternatively, it would be possible to define some DeviceState
methods also in the system crate, using for example a separate trace
SystemDeviceMethods. For now, keep all the methods in one crate and
link 200 unused lines of code into user-mode emulators.

rust: move hwcore::sysbus to system crate
This inverts the dependency from hwcore to system, replacing it with
a dependency from system to hwcore. It also matches how hw/core/sysbus.h
is part of the system-sys crate, and hw/core/sysbus.c is part of system_ss
on the C side.
This fixes a linker error in hwcore integration tests on msys2.

Move raw FFI bindings generation to separate crates. This makes it
possible to reuse bindgen declarations for a header file in its
dependencies (this was not the case before this change), while keeping
multiple -sys crates to avoid rebuilding all the code whenever
something changes.
Because the -sys crates are generated in dependency order, this also
enforces that the crates are organized in something that resembles
the dependencies between C headers.
The meson.build for rust-safe crates becomes simpler, and it should be
possible in the future to let Meson's cargo support handle most of it.

hw/vfio/region: Create dmabuf for PCI BAR per region
Linux now provides a VFIO dmabuf exporter to expose PCI BAR memory for P2P
use cases. Create a dmabuf for each mapped BAR region after the mmap is set
up, and store the returned fd in the region’s RAMBlock. This allows QEMU to
pass the fd to dma_map_file(), enabling iommufd to import the dmabuf and map
the BAR correctly in the host IOMMU page table.
If the kernel lacks support or dmabuf setup fails, QEMU skips the setup
and continues with normal mmap handling.

Make the synchronous calls evident by not hiding the call to
migration_channel_connect_outgoing() in the transport code. Have those
functions return and call the function at the upper level.
This helps with navigation: the transport code returns the ioc,
there's no need to look into them when browsing the code.
It also allows RDMA in the source side to use the same path as the
rest of the transports.
While here, document the async calls which are the exception.

After cleanups, the qmp_migrate_finish function is now just a call to
migration_connect_outgoing(). Remove qmp_migrate_finish() and rename
the qmp_migrate_finish_cb callback.
This also allows the function's error handling to be removed as it now
receives &local_err like the rest of the callees of qmp_migrate().

Move this CPR-specific code into a cpr file. While here, give the

migration: Free cpr-transfer MigrationAddress along with gsource
When setting a callback on a Glib source and giving it a data pointer,
it's natural to also provide the destructor for the data in question.
Since migrate_hup_add() already needs to clone the MigrationAddress
when setting the qmp_migrate_finish_cb callback, also pass the
qapi_free_MigrationAddress as the GDestroyNotify callback.
With this the address doesn't need to be freed at the callback body,
making the management of that memory slightly simpler.

fd_start_migration_outgoing becomes fd_connect_outgoing, the early

qemu-options.hx: Improve formatting in colo-compare docs
The colo-compare option documentation has some formatting issues: it
uses a "@var{...}" syntax which is not used elsewhere and which is
rendered literally into the HTML documentation. The bare "@" sign
also results in an unintended 'mailto:' hyperlink.
Rewrite this into the style we seem to use most in the rest of
the command line options, where an option which takes an argument
is written as "my-option=<thing>".
We take the opportunity to make the documentation a little clearer
by splitting up the long paragraph and using preformatted-text
markup for the names of the suboptions.

qemu-options.hx: Drop uses of @var
A few entries in qemu-options.hx use the syntax "my-option=@var{name}"
(or @var{} with no name specified) when documenting an option that takes
an argument. This syntax isn't consistently used, and the documentation
generation has no support for it: it just appears literally in the
HTML output.
Switch these uses to the more common "my-option=<name>". This also
doesn't have any particular support in the documentation generation
and so appears literally in the output, but it is a little less odd
looking to the end-user.
The other common pattern we have is "my-option=name" with no marking
at all that the right hand side of the '=' is not literal text;
using <> seems preferable to me, as it makes it more distinct from
cases where the right hand side is documenting that only certain
values are permitted, as in "my-option=on|off". This patch doesn't
do anything about existing uses of this pattern (except in one case
which was so confused as to use "my-option=@var{}" in the --help
output and "my-option=" in the RST output, where we change both
for consistency), but prefers not to add more of them.
We don't change the uses of @var in the colo-compare documentation,

is better in its own commit.
