Macro rusty_fork_test_name

macro_rules! rusty_fork_test_name {
    ($function_name:ident) => { ... };
}

Given the unqualified name of a #[test] function, produce a &'static str corresponding to the name of the test as filtered by the standard test harness.

This is internally used by rusty_fork_test! but is made available since other test wrapping implementations will likely need it too.

This does not currently produce a constant expression.
