userdiff: add built-in pattern for rust
This adds xfuncname and word_regex patterns for Rust, a quite popular programming language. It also includes test cases for the xfuncname regex (t4018) and updated documentation. The word_regex pattern finds identifiers, integers, floats and operators, according to the Rust Reference Book.
