The analyze-migration script was seen failing in s390x in misterious
ways. It seems we're reaching the VMSDFieldStruct constructor without
any fields, which would indicate an empty .subsection entry, a
VMSTATE_STRUCT with no fields or a vmsd with no fields. We don't have
any of those, at least not without the unmigratable flag set, so this
should never happen.
Add some debug statements so that we can see what's going on the next
time the issue happens.

checkpatch.pl lints for spaces around operators including / (slash).
Code lines starting with #include are ignored, as slashes in those
represent path separators.
In Objective-C code, #import is often used in preference to #include,
as preprocessor-based multiple-#include defenses are considered
non-idiomatic in that language.
This change extends checkpatch.pl to treat #import lines in the same
way as #include, avoiding false positives for "missing" spaces
around path separators on those lines.

Because Ubuntu 22.04 has a very old version of bindgen, that
does not have the important option --allowlist-file, it will
not be able to use --enable-rust out of the box. Instead,
install the latest version of bindgen-cli via "cargo install"
in the container, following QEMU's own documentation.

Occasionally, we may need to silence warnings and clippy lints that
were only introduced in newer Rust compiler versions. However, this
would fail when compiling with an older rustc:
error: unknown lint: `non_local_definitions`
--> rust/qemu-api/rust-qemu-api-tests.p/structured/offset_of.rs:79:17
So by default we need to block the unknown_lints warning. To avoid
misspelled lints or other similar issues, re-enable it in the CI job
that uses nightly rust.

Some applications want to use low priority realtime signals (e.g.,
SIGRTMAX). Currently QEMU cannot map all target realtime signals to
host realtime signals, and chooses to sacrifice the end of the target
realtime signal range.
Allow users to choose how to map target realtime signals to host
realtime signals using the new -t option, the new QEMU_RTSIG_MAP
environment variable, and the new -Drtsig_map=\"...\" meson flag.
To simplify things, the meson flag is not per-target, because the
intended use case is app-specific qemu-user builds.
The mapping is specified using the "tsig hsig count[,...]" syntax.
Target realtime signals [tsig,tsig+count) are mapped to host realtime
signals [hsig,hsig+count). Care is taken to avoid double and
out-of-range mappings.

Although we're not enabling rust by default yet, we can still add
rust and bindgen to the CI package list.
This demonstrates that we're not accidentally triggering unexpected
build behaviour merely from Rust being present. When we do dev work
to enable rust by default, this will show we're building correctly
on all platforms we target.

The arguments in MESONINTROSPECT are quoted with shlex.quote() so it
must be parsed with shlex.split(). Otherwise the script will fail if
the build directory has a character like "~" in it.
Note: this fix cannot be backported directly to any stable branch
that doesn't require Meson version 1.4.0 or better; otherwise it will
work OK on Linux but will break on Windows hosts.
(Unfortunately, Meson prior to version 1.4.0 was inconsistent between
host OSes about how it quoted arguments, and used a different quoting
process on Windows hosts. Our current git trunk already requires
1.5.0 as of commit 07f0d32641 ("Require meson version 1.5.0"), but
the stable branches are still on older Meson.)

This commit adds a helper crate library, qemu-api-macros for derive (and
other procedural) macros to be used along qemu-api.
It needs to be a separate library because in Rust, procedural macros, or
macros that can generate arbitrary code, need to be special separate
compilation units.
Only one macro is introduced in this patch, #[derive(Object)]. It
generates a constructor to register a QOM TypeInfo on init and it must
be used on types that implement qemu_api::definitions::ObjectImpl trait.
