SQLite loading can't be interrupted by ctrl+c

[rgwood]

Describe the bug

If you open foo.db on a large SQLite database, it will take a very long time and can't be interrupted by ctrl+c.

It's tricky to fix this because the SQLiteDatabase struct implements CustomValue, and CustomValue impls must derive Serialize+Deserialize because CustomValue uses typetag. And so we can't just add a ctrlc: Option<Arc<AtomicBool>> field to SQLiteDatabase because that can't be serialized...

This is getting into some rather complicated areas of Rust, hopefully someone can find a good solution.

How to reproduce

1. open foo.db
2. press ctrl+c, it does nothing

Expected behavior

ctrl+c should interrupt opening a database.
