This customizes the subset of the Rust standard library `alloc` that
was just imported as-is, mainly by:
- Adding SPDX license identifiers.
- Skipping modules (e.g. `rc` and `sync`) via new `cfg`s.
- Adding fallible (`try_*`) versions of existing infallible methods
(i.e. returning a `Result` instead of panicking).
Since the standard library requires stable/unstable attributes,
these additions are annotated with:
#[stable(feature = "kernel", since = "1.0.0")]
Using "kernel" as the feature allows to have the additions
clearly marked. The "1.0.0" version is just a placeholder.
(At the moment, only one is needed, but in the future more
fallible methods will be added).
