rs_bindings_from_cc: Map cc_library targets named 'core' to 'core_<last_package_path_component>'. So that `::core` in generated bindings correctly resolves to Rust's 'core' crate. While adding more integration tests for escaping core, I realized that Crubit's code generation needs to be made aware of the renaming of cc_library targets named 'core' AND mapping of invalid characters to underscore as well, so I added logic for this.

Crubit is a bidirectional bindings generator for C++ and Rust.
Please don‘t use, this is an experiment and we don’t yet know where will it take us. There will be breaking changes without warning. Unfortunately, we can't take contributions at this point.
Crubit allows for C++ code and Rust code to call each other without manually wrapping the APIs in an FFI-friendly interop layer. For example, a C++ function like this:
bool IsAbsPath(std::string_view path);
... becomes callable from Rust as if it were defined as:
pub fn IsAbsPath(path: std::string_view) -> bool {...}
Crubit automatically generates ABI-compatible bindings for structs (which can be passed both by value and by reference), functions, and methods, for a large variety of types. (Trivial types, nontrivial types, templated types, etc.)
