Handle more conversions between Rust types and C types. #11

Currently does not handle any pointers.
- Do we force the programmers to use pointers or do we do some magic behind the scenes with references?
How do we handle strings?
Should we warn (or even error) on any types?

zsiciarz/rust-ffi-stringtools might come in handy.

Also this.

We can't do anything behind the scenes now that we use a drop-in so error on references.

How do we handle strings?

Error, note that you should be using *u8 or *mut u8.

52a98fc170836b3be00a7b2b1faf4ab5a9efa3bb means that the only thing left is to warn/error on incompatible type.

The best thing to do would be to warn/error on types which aren't pointers, fn pointers, or paths and warn/error on non-libc paths which have multiple components.
