annotate src/libpam/conversation.rs @ 98:b87100c5eed4

Start on environment variables, and make pointers nicer. This starts work on the PAM environment handling, and in so doing, introduces the CHeapBox and CHeapString structs. These are analogous to Box and CString, but they're located on the C heap rather than being Rust-managed memory. This is because environment variables deal with even more pointers and it turns out we can lose a lot of manual freeing using homemade smart pointers.
