//! \brief A CrashReportDatabase that uses HFS+ extended attributes to store
//! report metadata.
//!
//! The database maintains three directories of reports: `"new"` to hold crash
//! reports that are in the process of being written, `"completed"` to hold
//! reports that have been written and are awaiting upload, and `"uploaded"` to
//! hold reports successfully uploaded to a collection server. If the user has
//! opted out of report collection, reports will still be written and moved
//! to the completed directory, but they just will not be uploaded.
//!
//! The database stores its metadata in extended filesystem attributes. To
//! ensure safe access, the report file is locked using `O_EXLOCK` during all
//! extended attribute operations. The lock should be obtained using
//! ObtainReportLock().
