rust: syn: add `README.md`

2025-11-24T16:15:47+00:00

Originally, when the Rust upstream `alloc` standard library crate was vendored in commit 057b8d257107 ("rust: adapt `alloc` crate to the kernel"), a `README.md` file was added to explain the provenance and licensing of the source files. Thus do the same for the `syn` crate.

rust: syn: remove `unicode-ident` dependency

2025-11-24T16:15:46+00:00

The `syn` crate depends on the `unicode-ident` crate to determine whether characters have the XID_Start or XID_Continue properties according to Unicode Standard Annex #31. However, we only need ASCII identifiers in the kernel, thus we can simplify the check and remove completely that dependency.

rust: syn: add SPDX License Identifiers

2025-11-24T16:15:45+00:00

Originally, when the Rust upstream `alloc` standard library crate was vendored in commit 057b8d257107 ("rust: adapt `alloc` crate to the kernel"), the SPDX License Identifiers were added to every file so that the license on those was clear. Thus do the same for the `syn` crate. This makes `scripts/spdxcheck.py` pass.
