While working on #7345, I grew dissatisfied with how Geary.Attachment was implemented. It knew too much about imap-db's internal workings, so I've broken it up a little bit. It's now an abstract base class completed by ImapDB.Attachment, a private implementation class. This corresponds with the coding patterns used throughout the Geary API.
