C-Side Tourism: Using C libraries from Rust

There's a wild world of C software out there just waiting to serve a
Rustacean's needs, but the terrain can be rocky and unfamiliar.
Even if you're already comfortable with Rust, C, or both, wrapping C
libraries with FFI can be tricky to navigate.

This month, Owen Nelson (@theomn) will recall some of the sights he
saw on his recent visits to the C-Side. Hopefully, once you've seen
some snapshots of the local landmarks, you'll be encouraged to take a
trip of your own!
