**   Log files are read using the "vfslog" virtual table implementation
**   in this file. To register the virtual table with SQLite, use:
**
**       int sqlite3_vfslog_register(sqlite3 *db);
**
................................................................................
**         event    TEXT,             // "xOpen", "xRead" etc.
**         file     TEXT,             // Name of file this call applies to
**         clicks   INTEGER,          // Time spent in call
**         rc       INTEGER,          // Return value
**         size     INTEGER,          // Bytes read or written
**         offset   INTEGER           // File offset read or written
**       );
