Move freetype binding to separate module.

This makes it more like the others, and will keep it cleaner when we go and bind the other functions in this module.

This looks fine to me and I like the cleanup. The only issue here is that the new file is missing a license header. I understand that there are many files missing headers, but that's another issue we will need to fix. :)

Can I just add them all at once in something separate?

I think adding the license header now and cleaning up the rest of the files later makes more sense. It's not great to have code without a proper license checked in.

Give me the text you want, and I'll add it.

None of the files in the harfbuzz-sys have a copyright / license header. The files in harfbuzz do. But the licenses are not the same. The harfbuzz-sys crate is MIT, while harfbuzz is MIT OR Apache 2.0.

(That's why I don't want to do it here: It is likely to be bikeshedded and no files in this crate have one.)

The header refers to both licenses. I assume that MIT is included here because that is what HarfBuzz uses, but the rust code itself is specifically licensed under Apache as well.

Okay, added here, and the rest of the files and such updated in #225.

Thanks!
