2022-12-04	rust: add `build_error` crate	Gary Guo
	The `build_error` crate provides a function `build_error` which will panic at compile-time if executed in const context and, by default, will cause a build error if not executed at compile time and the optimizer does not optimise away the call. The `CONFIG_RUST_BUILD_ASSERT_ALLOW` kernel option allows to relax the default build failure and convert it to a runtime check. If the runtime check fails, `panic!` will be called. Its functionality will be exposed to users as a couple macros in the `kernel` crate in the following patch, thus some documentation here refers to them for simplicity.

2022-09-28	rust: export generated symbols	Miguel Ojeda
	All symbols are reexported reusing the `EXPORT_SYMBOL_GPL` macro from C. The lists of symbols are generated on the fly. There are three main sets of symbols to distinguish: - The ones from the `core` and `alloc` crates (from the Rust standard library). The code is licensed as Apache/MIT. - The ones from our abstractions in the `kernel` crate. - The helpers (already exported since they are not generated). We export everything as GPL. This ensures we do not mistakenly expose GPL kernel symbols/features as non-GPL, even indirectly.
