Simplified the first examples to demonstrate callbacks without other threads involved and shortened the elaboration about async callbacks.

I wrote a chapter for the FFI tutorial that describes how to perform callbacks from C code to Rust and gives some hints about what to consider and synchronization. I just needed that for my own wrapper and thought it would be helpful for others.
