27 * ASL Database VERSION 1 (LEGACY)
28 *
29 * Log messages are stored in 80 byte records of the form:
30 *
31 * | 1    | 4    | 8  | 4    | 4    | 8    | 8    | 8      | 8        | 4     | 4   | 4   | 4   | 8       | 2     | 1    | (80 bytes)
32 * | Type | Next | ID | RUID | RGID | Time | Host | Sender | Facility | LEVEL | PID | UID | GID | Message | Flags | Zero |
33 *
34 * If there are no additional key/value pairs in the message, Next will be zero.  If there are additional
35 * key/value pairs in the database, Next is a record number for a record with the format:
36 *
37 * | 1    | 4    | 4      | 8    | 8    | 8    | 8    | 8    | 8    | 8    | 8    | 7    | (80 bytes)
38 * | Type | Next | Count  | Key1 | Val1 | Key2 | Val2 | Key3 | Val3 | Key4 | Val4 | Zero |
39 *
40 * Additional records will be chained using the Next field, with the count field left zero.
41 *
42 * Strings stored in records of the form:
43 *
44 * | 1    | 4    | 8  | 4        | 4    | 4      | 55     | (80 bytes)
45 * | Type | Next | ID | Refcount | Hash | Length | String |
46 *
47 * If the string is longer than 55 bytes, Next is a record number for a record with the format:
48 *
49 * | 1    | 4    | 75     | (80 bytes)
50 * | Type | Next | String |
51 *
52 * The first record (header) in the database has the format:
53 *
54 * | 12     | 4    | 8      | 56   | (80 bytes)
55 * | Cookie | Vers | Max ID | Zero |
