/* Open an existing notmuch database located at 'path'.
 *
 * The database should have been created at some time in the past,
 * (not necessarily by this process), by calling
 * notmuch_database_create with 'path'. By default the database should be
 * opened for reading only. In order to write to the database you need to
 * pass the NOTMUCH_DATABASE_MODE_READ_WRITE mode.
 *
 * An existing notmuch database can be identified by the presence of a
 * directory named ".notmuch" below 'path'.
 *
 * The caller should call notmuch_database_destroy when finished with
 * this database.
 *
 * In case of any failure, this function returns NULL, (after printing
 * an error message on stderr).
