Marc-André Lureau	c899071b5a	rust: move binding generation to bindings/ 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.

Martin Kletzander	9be6962015	rust: Do not link qemuutil into Rust rlibs Commit de037ab8d83d removed qemuutil dependency from chardev and util rust crates. However it stayed in the _util_rs static library. The dependency is also defined as `link_with`, which is fine for C targets, where the resulting archive gets linked as another parameter on the command line when it is a static library. However, when a C library is linked into a Rust rlib, rustc remembers the dependency into the metadata and adds the library to the linker command line. Unfortunately, static libraries are sensitive to their position on the command line and rustc does not always get it right. Fortunately, simply removing it from dependencies of any rust libraries and instead adding them into the dependencies of executables and doctests fixes the behaviour. Without this patch the error I get is: FAILED: [code=1] rust/tests/rust-integration ... = note: rust-lld: error: unable to find library -l:libqemuutil.a rust-lld: error: unable to find library -l:libvhost-user-glib.a rust-lld: error: unable to find library -l:libvhost-user.a rust-lld: error: unable to find library -l:libqemuutil.a rust-lld: error: unable to find library -l:libvhost-user-glib.a rust-lld: error: unable to find library -l:libvhost-user.a rust-lld: error: unable to find library -l:libqemuutil.a rust-lld: error: unable to find library -l:libvhost-user-glib.a rust-lld: error: unable to find library -l:libvhost-user.a rust-lld: error: unable to find library -l:libqemuutil.a rust-lld: error: unable to find library -l:libvhost-user-glib.a rust-lld: error: unable to find library -l:libvhost-user.a rust-lld: error: unable to find library -l:libqemuutil.a rust-lld: error: unable to find library -l:libvhost-user-glib.a rust-lld: error: unable to find library -l:libvhost-user.a rust-lld: error: unable to find library -l:libqemuutil.a rust-lld: error: unable to find library -l:libvhost-user-glib.a rust-lld: error: unable to find library -l:libvhost-user.a collect2: error: ld returned 1 exit status Meson could work around it itself by never adding these static libraries to the rlibs (after all, Meson tracks the transitive dependencies already and knows how to add them to dependents of those rlibs); at least for now, do it in QEMU: never link C libraries into Rust rlibs, and add them to the final build products only.

Paolo Bonzini	02d6b8cfd3	rust: do not add qemuutil to Rust crates This fails due to https://github.com/mesonbuild/meson/pull/15076. The config-host.h file from the qemuutil dependency ends up on the rustc command line for targets that do not use structured sources. It will be reverted once Meson 1.9.2 is released.

Martin Kletzander	80a3c9c01a	rust: remove useless glib_sys bindings The definition of types needed for g_autolist(), g_autoslist(), g_autoqueue() need the imports for GList, GSList and GQueue to appear everything. Rust code is never going to see those, since they are not used in structs. Block the types from appearing in the bindings.
