Subject: [Rust] Simplify usage surrounding c strings

`cstring.as_ref().as_ptr() as *const c_char` -> `cstring.as_ptr()`
`cstring.as_ref().as_ptr() as *mut _` -> `cstring.as_ptr()`
`cstring.as_ptr() as *const c_char` -> `cstring.as_ptr()`

With a few fixes for cstrings that might be dropped prematurely.
