Floris Bruynooghe 4c646dc1e0 Rename dc_chat_t to Chat
This clears the way to start working on making the functions safe.
But small PRs are good PRs so let's get this rename out of the way and
have future PRs less noisy.

Also stop making this #[repr(C)] and start making fields that are not
used private. Lastly clean up some comments by moving them or
deleting them, so they make sense again after the translation.
