Many headers don't really need to include database.hh, the include can be replaced by forward declarations and/or including the actually needed headers directly. Some headers don't need this include at all. Each header was verified to be compilable on its own after the change, by including it into an empty `.cc` file and compiling it. `.cc` files that used to get `database.hh` through headers that no longer include it were changed to include it themselves.
