modules: Add an unstable-rust module Like other language specific modules this module is module for holding rust specific helpers. This commit adds a test() function, which simplifies using rust's internal unittest mechanism. Rust tests are generally placed in the same code files as they are testing, in contrast to languages like C/C++ and python which generally place the tests in separate translation units. For meson this is somewhat problematic from a repetition point of view, as the only changes are generally adding --test, and possibly some dependencies. The rustmod.test() method provides a mechanism to remove the repatition: it takes a rust target, copies it, and then addes the `--test` option, then creates a Test() target with the `rust` protocol. You can pass additional dependencies via the `dependencies` keyword. This all makes for a nice, DRY, test definition.

if T.TYPE_CHECKING:
Simplify module API - ModuleState is now a real class that will have methods in the future for actions modules needs, instead of using interpreter internal API. - New ModuleObject base class, similar to InterpreterObject, that should be used by all objects returned by modules. Its methods gets the ModuleState passed as first argument. It has a `methods` dictionary to define what is public API that can be called from build definition. - Method return value is not required to be a ModuleReturnValue any more, it can be any type that interpreter can holderify, including ModuleObject. - Legacy module API is maintained until we port all modules. In the future modules should be updated: - Use methods dict. - Remove snippets. - Custom objects returned by modules should all be subclass of ModuleObject to get the state iface in their methods. - Modules should never call into interpreter directly and instead state object should have wrapper API. - Stop using ModuleReturnValue in methods that just return simple objects like strings. Possibly remove ModuleReturnValue completely since all objects that needs to be processed by interpreter (e.g. CustomTarget) should be created through ModuleState API.

Make compilers list per subproject Previously subprojects inherited languages already added by main project, or any previous subproject. This change to have a list of compilers per interpreters, which means that if a subproject does not add 'c' language it won't be able to compile .c files any more, even if main project added the 'c' language. This delays processing list of compilers until the interpreter adds the BuildTarget into its list of targets. That way the interpreter can add missing languages instead of duplicating that logic into BuildTarget for the cython case.

rust: Add a module wrapper for bindgen This has a couple of advantages over rolling it by hand: 1. it correctly handles include_directories objects, which is always handy 2. it correctly generates a depfile for you, which makes it more reliable 3. it requires less typing

modules: Add an unstable-rust module Like other language specific modules this module is module for holding rust specific helpers. This commit adds a test() function, which simplifies using rust's internal unittest mechanism. Rust tests are generally placed in the same code files as they are testing, in contrast to languages like C/C++ and python which generally place the tests in separate translation units. For meson this is somewhat problematic from a repetition point of view, as the only changes are generally adding --test, and possibly some dependencies. The rustmod.test() method provides a mechanism to remove the repatition: it takes a rust target, copies it, and then addes the `--test` option, then creates a Test() target with the `rust` protocol. You can pass additional dependencies via the `dependencies` keyword. This all makes for a nice, DRY, test definition.
