meson: specify minimal target meson version for rust subprojects Silences several meson warnings like: ``` ../subprojects/equivalent-1.0.1/meson.build:9: WARNING: Project does not target a minimum version but uses feature introduced in '1.3.0': rust_abi arg in static_library. ``` The target of 1.7.0 was chosen since that's the minimal required meson version of the rust components in mesa anyway.

meson: rename Rust subprojects to NAME-SEMVER-rs Use the convention for Rust subprojects that was adopted by Meson 1.5.0 and newer. Distros would prefer to avoid vendored crate sources, and instead use local sources from e.g. /usr/share/cargo/registry. While Meson does not support a local registry, it can be emulated with MESON_PACKAGE_CACHE_DIR. However, because the distro might not be using the exact version of the package, but only one that has the same semver, packagers need to add some hacks to rewrite the wrap files. For example, in Fedora: export MESON_PACKAGE_CACHE_DIR="%{cargo_registry}/" # So... Meson can't actually find them without tweaks %define inst_crate_nameversion() %(basename %{cargo_registry}/%{1}-*) %define rewrite_wrap_file() sed -e "/source.*/d" -e "s/%{1}-.*/%{inst_crate_nameversion %{1}}/" -i subprojects/%{1}.wrap %rewrite_wrap_file proc-macro2 %rewrite_wrap_file quote %rewrite_wrap_file syn %rewrite_wrap_file unicode-ident %rewrite_wrap_file paste Having a common convention for the name of Rust wraps makes it possible to perform this transformation with a script without listing the wraps one by one, and to share the script across multiple packages (which will be useful when QEMU starts using Rust in a similar way to Mesa). For an example of such a script, see https://lore.kernel.org/r/20250722083507.678542-1-pbonzini@redhat.com/.

meson: silence warnings in rust subprojects Rust 1.91 as well as clippy show various benign warnings in our dependencies. Silence them since we can't really do much about them anyway and we want to enforce clippy complience via CI in the future. Matches cargo behavior, which also doesn't show warnings or clippy lints outside the workspace.

util: be consistent about transitive dependencies A transitive dependency is a dependency of a dependency. So if, for example, mesa3d_util does explicitly use zerocopy-derive, it should not need to a depend on it. The package that pulls in transitive should already include it has a dependency. This provides clearer methodologies in maintaining Rust code, similiar to how Cargo.toml handles it. Reviewed-by: David Gilhooley <djgilhooley.gmail.com>
